What Is HashiCorp?

HashiCorp is a software company that builds tools to automate the management of infrastructure in the cloud and on-premises environments.

Founded in 2012, HashiCorp is widely known in the DevOps and cloud-native community for providing a modular set of open-source tools that help developers, system administrators, and operations teams provision, secure, connect, and run infrastructure efficiently.

Each tool in the HashiCorp ecosystem solves a specific problem in the infrastructure lifecycle. Terraform, one of its most popular tools, allows users to define infrastructure as code in a declarative language, making it possible to automate cloud provisioning across providers like AWS, Azure, and GCP.

Vault is a tool for securely managing secrets, credentials, tokens, and encryption keys, enabling organizations to move toward a Zero Trust security model.

Consul focuses on service discovery, health checking, and service-to-service networking, often used in dynamic microservices architectures and service meshes.

Nomad is a lightweight orchestrator that can schedule and run containers, virtual machines, or any executable workloads across clusters.

All of these tools can be used independently or together to build a fully automated, secure, and scalable infrastructure platform. What sets HashiCorp apart is its cloud-agnostic philosophy tools are designed to work across any environment, not just one vendor.

The tools follow a Unix-like approach of doing one thing well and integrating cleanly with others. HashiCorp offers both open-source versions and enterprise-grade solutions with advanced features like role-based access control, auditing, governance, and cloud-managed services.

Whether you are managing a few cloud resources or operating a complex hybrid infrastructure, HashiCorp tools help you reduce manual effort, improve reliability, and scale with confidence.

From startups to Fortune 500 companies, teams around the world rely on HashiCorp to modernize how infrastructure is delivered, secured, and operated.

The Core HashiCorp Toolchain

HashiCorp’s tools are often divided into four functional categories:

Terraform – Infrastructure as Code.

Terraform is an open-source tool developed by HashiCorp that enables users to define and manage infrastructure using code a practice known as Infrastructure as Code (IaC).

Instead of manually provisioning servers, databases, or networking components through a cloud provider’s web console, you write configuration files in a human-readable language called HCL (HashiCorp Configuration Language).

These files describe the desired state of your infrastructure, and Terraform takes care of creating, updating, or deleting resources to match that state.

It supports a wide range of providers, including AWS, Azure, GCP, and many others, allowing you to manage cloud infrastructure in a consistent way.

One of Terraform’s key advantages is its declarative approach: you tell Terraform what you want, and it figures out how to make it happen.

It uses a state file to keep track of your deployed infrastructure, which allows it to detect changes and avoid unnecessary updates.

Terraform also offers features like execution plans, so you can preview changes before applying them, and modules, which let you reuse code for repeatable patterns. Whether you’re deploying a single virtual machine or orchestrating complex cloud environments, Terraform helps teams automate, standardize, and version-control infrastructure reliably.

Vault – Secrets and Identity Management.

Vault is a powerful open-source tool by HashiCorp designed for managing secrets, identity, and encryption in modern infrastructure. In a world where applications, services, and humans all require secure access to systems, Vault provides a centralized, auditable way to manage sensitive data.

It eliminates the need to hardcode secrets like API keys, passwords, and certificates in code or config files. Instead, secrets are stored securely and accessed via API calls.

Vault supports dynamic secrets, which are generated on demand and expire after use this is ideal for short-lived database or cloud credentials. It also offers encryption as a service, allowing applications to offload data encryption without managing complex key lifecycles.

With support for various authentication backends (like AWS IAM, GitHub, LDAP, or Kubernetes), Vault helps unify identity-based access control across platforms.

All access is governed by fine-grained policies, ensuring that users and services can only access what they’re permitted to.

Vault’s audit logging capabilities add transparency and traceability to secret access. It can be self-hosted or consumed as a cloud service via Vault Cloud.

Whether you’re securing microservices, rotating credentials, or protecting sensitive data at scale, Vault provides a flexible, robust foundation for secrets and identity management in any environment.

Consul – Service Discovery and Service Mesh

Consul is a service networking tool from HashiCorp that provides service discovery, health checking, configuration management, and service mesh capabilities.

In dynamic environments like microservices or Kubernetes, services need to find and communicate with each other reliably.

Consul solves this by acting as a central registry, where services register themselves and can discover others through DNS or HTTP APIs.

It includes built-in health checks to ensure traffic is only routed to healthy instances. Consul also stores key/value data for dynamic configuration across services.

Beyond basic discovery, Consul supports a full service mesh, integrating with Envoy to provide features like secure service-to-service communication (mTLS), traffic shaping, and observability. It works in cloud, hybrid, and on-prem environments, making it highly flexible.

Consul’s architecture supports multi-datacenter deployments, enabling global scale. With Consul, teams gain visibility, reliability, and security in how their services connect without hardcoding endpoints or managing complex networking logic.

Nomad – Application Scheduling and Orchestration

Nomad is a flexible, lightweight workload orchestrator developed by HashiCorp that allows you to deploy and manage applications across clusters of machines.

Unlike more complex platforms like Kubernetes, Nomad is designed to be simple to operate, with a small binary and minimal dependencies.

It supports a wide range of workloads including containers (like Docker), virtual machines, Java JARs, binaries, and even legacy apps making it suitable for both modern and traditional environments.

Nomad uses a declarative job specification to define tasks and handles scheduling, resource allocation, scaling, and failover automatically. It integrates seamlessly with other HashiCorp tools: Consul for service discovery and Vault for secrets management.

Nomad is built with a single binary architecture, which simplifies deployment and lowers the barrier to entry compared to other orchestrators.

It supports multi-region and multi-cloud setups, enabling high availability and resilience across environments. With built-in auto-scaling, preemption, and resource isolation, Nomad is capable of running high-scale production workloads efficiently.

Its straightforward design and flexibility make it especially attractive to teams looking for a production-grade orchestrator without the operational complexity of Kubernetes.

The HashiCorp Philosophy

HashiCorp tools are built with a modular, cloud-agnostic design. This means:

• You can use just one tool (like Terraform) or combine several
• They work across all major clouds and on-prem infrastructure
• They follow the Unix philosophy: each tool does one thing well

This makes the ecosystem flexible, interoperable, and easy to adopt incrementally.

Open Source and Enterprise Options

All HashiCorp tools are available in open-source, community-driven editions. For larger organizations, enterprise versions provide:

• Governance and compliance features
• Role-based access control (RBAC)
• Multi-tenancy and team support
• Audit logging and integrations with SSO, LDAP, etc.

HashiCorp also offers cloud-managed services (e.g., Terraform Cloud, Vault Cloud) for teams that don’t want to self-host.

Conclusion.

HashiCorp offers one of the most respected and widely adopted toolchains in cloud infrastructure management.

Whether you’re just getting started with Terraform or looking to secure microservices with Vault and Consul, the HashiCorp ecosystem provides the building blocks to automate and modernize your infrastructure.

If you’re learning DevOps, HashiCorp tools are essential to know. And if you’re part of a growing engineering team, they can help you scale faster—with more control, security, and consistency.

What Is Terraform?

Terraform is an open-source Infrastructure as Code (IaC) tool created by HashiCorp that allows users to define and provision infrastructure using a high-level, declarative configuration language called HCL (HashiCorp Configuration Language).

Instead of manually setting up servers, databases, networking, and other cloud components through a web console or CLI, Terraform enables you to describe what your infrastructure should look like in code and then automatically builds and maintains it.

Terraform supports a wide range of service providers, including public clouds like AWS, Azure, and Google Cloud Platform, as well as other platforms like Kubernetes, GitHub, and even on-prem systems via third-party providers.

The key strength of Terraform lies in its declarative model, where you state the desired outcome, and Terraform figures out the steps needed to reach that state. This contrasts with imperative approaches, where you must write each action step-by-step.

Terraform configurations are idempotent, meaning you can apply them repeatedly with the same result, making it easy to manage infrastructure consistently and predictably.

At the heart of Terraform’s operation is its state file, which keeps track of the resources it manages, allowing it to detect changes, create dependency graphs, and plan updates efficiently.

The Terraform lifecycle consists of three main phases: init, which sets up the working directory; plan, which shows what changes will occur; and apply, which executes those changes.

This enables infrastructure changes to be reviewed before being made, improving safety and transparency. Terraform promotes modularity, allowing users to break infrastructure into reusable modules that can be shared across teams or projects.

It also integrates well with version control systems like Git, enabling teams to collaborate on infrastructure using pull requests and code reviews. By using remote backends such as Amazon S3 with DynamoDB for state locking, teams can safely manage infrastructure concurrently.

Additionally, Terraform can be integrated with CI/CD pipelines for automated deployment workflows. It supports input variables, output values, conditionals, loops, and even dynamic blocks, giving it powerful flexibility while remaining human-readable.

The open-source nature of Terraform means a rich ecosystem of community-contributed modules and providers exists, making it faster to build infrastructure for common use cases. For sensitive environments, Terraform can be used alongside secrets managers like Vault, AWS SSM, or environment variables to protect confidential data.

While Terraform is not a configuration management tool like Ansible or Chef (which manage software inside servers), it complements those tools by focusing on the provisioning of infrastructure resources. The growing popularity of cloud-native and DevOps practices has made Terraform a go-to tool in modern infrastructure engineering.

With its strong multi-cloud capabilities, infrastructure versioning, and emphasis on reproducibility, Terraform helps organizations treat their infrastructure as software.

This mindset reduces human error, increases deployment speed, and aligns infrastructure workflows with software development best practices. As more companies adopt cloud infrastructure at scale, Terraform becomes essential for managing complexity, standardizing environments, and enforcing compliance through code.

Whether you’re building a single VM or orchestrating thousands of resources across multiple providers, Terraform offers a powerful, consistent way to manage it all. Terraform is a versatile, cloud-agnostic infrastructure automation tool that empowers engineers to build, change, and version infrastructure safely and efficiently using code.

Why Use Terraform?

Terraform is widely used because it brings automation, consistency, and control to infrastructure management. Instead of manually provisioning resources through cloud provider dashboards or CLI tools, Terraform allows you to define infrastructure in code, making it repeatable, version-controlled, and easily auditable.

This Infrastructure as Code (IaC) approach helps teams collaborate more effectively, reduces the chance of human error, and ensures environments are always built the same way.

One of Terraform’s standout features is its declarative syntax, where you describe the desired infrastructure state and Terraform figures out the steps to achieve it. This reduces complexity and improves maintainability.

Another major advantage is multi-cloud support with providers for AWS, Azure, GCP, Kubernetes, and more, Terraform lets teams work across environments using a single tool and language.

Its execution plan (terraform plan) gives you a preview of what changes will occur before anything is applied, improving safety and confidence in deployments.

Terraform also supports modular infrastructure, encouraging best practices like reusability, separation of concerns, and easier scaling. Its ability to track infrastructure changes through a state file makes it intelligent about what needs to change, preventing unnecessary updates or redeployments.

Teams can manage shared infrastructure collaboratively using remote backends and state locking, avoiding race conditions in production.

It fits naturally into DevOps workflows, integrates easily with CI/CD pipelines, and supports infrastructure testing through tools like Terratest.

Terraform is cloud-agnostic, community-driven, and constantly evolving. Whether you’re spinning up a development environment or managing thousands of production systems, Terraform brings a reliable, codified foundation to modern infrastructure.

Core Concepts

Understanding these key Terraform concepts helps you use it effectively:

1. Providers

Terraform interacts with platforms via providers. Each provider (like aws, azurerm, or google) offers a set of resources Terraform can manage.

Example: The aws provider allows you to manage AWS services like EC2, S3, RDS, etc.

2. Resources

A resource is any piece of infrastructure you want to manage — a virtual machine, an S3 bucket, a VPC, etc.

Example:

resource "aws_instance" "web" {
  ami           = "ami-123456"
  instance_type = "t2.micro"
}

3. Variables and Outputs

• Variables allow you to reuse values and make your configurations dynamic.
• Outputs let you extract and display important information after provisioning (like an IP address).

4. State

Terraform maintains a state file that tracks what infrastructure has been deployed. This is how Terraform knows whether something needs to be added, changed, or destroyed.

This file can be local (terraform.tfstate) or stored remotely for team use (like in AWS S3 with locking via DynamoDB).

5. Plan → Apply Cycle

The Terraform lifecycle has two main phases:

• terraform plan: Shows what Terraform will do (create, destroy, change).
• terraform apply: Actually makes the changes in your infrastructure.

This makes changes predictable and reviewable before execution.

Declarative vs. Imperative

The declarative model is centered on describing the desired end state, without explicitly instructing the system how to reach that state. It answers the question: “What should the system look like?”

In this model, the responsibility of determining how to reach the desired configuration is left to the underlying tool or system.

Example in infrastructure:

A Terraform configuration might declare that an S3 bucket should exist, without any logic on how to create or manage it step by step. Terraform figures out what actions to take to match your desired outcome.

Declarative approaches are idempotent, meaning applying the same configuration repeatedly results in the same state, with no unintended side effects. This makes systems predictable, repeatable, and easier to maintain.

Common Declarative Tools:
Terraform, Kubernetes YAML, CloudFormation, Ansible (in some use cases), SQL

Imperative: Defining the How

The imperative model, in contrast, focuses on how to perform a sequence of actions to reach a desired outcome. It answers the question: “What steps should be executed?”

In imperative programming, you write a series of instructions that the system follows step by step, with full control over execution flow.

Example in infrastructure:

Using the AWS CLI, you might write a script that first checks for a bucket, creates it if it doesn’t exist, applies policies, and logs output. You define every single action.

This gives fine-grained control but shifts the burden of managing state, errors, and order of operations to the user. Imperative scripts can become complex and harder to maintain as systems scale.

Common Imperative Tools:
Bash, Python scripts, AWS CLI, Terraform’s local-exec (limited cases), Ansible playbooks (in some styles)

Comparing the Two Paradigms

Real-World Applications

• Provisioning infrastructure on any major cloud provider
• Setting up Kubernetes clusters
• Automating VPC networking and security
• Managing DNS, CDN, databases, or load balancers

Limitations to Be Aware Of.

State File Management
Terraform relies on a state file (terraform.tfstate) to track infrastructure. If this file is lost, corrupted, or out of sync, Terraform can no longer manage resources reliably. Managing state securely and consistently (especially with remote backends) is essential.

Sensitive Data Exposure
Secrets, passwords, and keys can end up in the state file, logs, or plan output. If not encrypted or stored securely, this can lead to sensitive data leaks. Extra care must be taken to use secret managers and avoid hardcoding credentials.

Lack of Fine-Grained Execution Control
Terraform applies changes to the entire plan, and you can’t easily execute a single resource in isolation (like imperative scripts can). This can make debugging or incremental changes more difficult.

Limited Error Handling
Terraform lacks native error-catching or retry mechanisms for transient failures (e.g., a temporary cloud API outage). If something fails mid-apply, manual cleanup or investigation is often required.

Drift Detection Is Passive
Terraform doesn’t automatically detect changes made outside of it (called drift) unless you run terraform plan or terraform refresh. This can lead to mismatches between your code and real-world infrastructure.

Complex Dependency Management in Large Projects
As infrastructure scales, dependency graphs between modules and resources can become complex and difficult to manage or troubleshoot. Terraform does its best to handle this, but large configurations require thoughtful design.

Slow Adoption of Provider Features
New features from cloud providers may not be immediately supported by Terraform providers. You might have to wait for community updates or contribute patches yourself, slowing down access to cutting-edge functionality.

Conclusion.

Terraform offers a powerful, consistent, and scalable way to manage infrastructure across cloud providers. By shifting from manual provisioning to Infrastructure as Code, you gain not only efficiency, but also visibility, repeatability, and collaboration across teams.

In this guide, we covered the core theoretical foundations — from what Terraform is, to how it works under the hood. Understanding key concepts like providers, resources, state, and the plan/apply lifecycle gives you a strong foundation to build on.

As you move forward, keep this in mind: Terraform isn’t just about writing code — it’s about changing the way infrastructure is built and maintained.

In our next post, we’ll put theory into practice by writing a simple Terraform configuration to deploy real cloud infrastructure.

Introduction.

In today’s digital landscape, users expect websites and applications to be lightning-fast, always available, and responsive across every device and region. Whether it’s an e-commerce platform during a flash sale, a SaaS dashboard handling global traffic, or a content-heavy blog serving millions of monthly readers, performance matters immensely.

But as applications grow more complex and audiences more geographically diverse, delivering consistent speed and reliability becomes a serious engineering challenge.

This is especially true for DevOps teams, who are tasked with maintaining performance, uptime, and scalability without compromising on development velocity or deployment frequency.

When a user accesses your application, every millisecond counts. Load times impact everything from SEO rankings to user retention and conversion rates.

Slow performance isn’t just an inconvenience it can translate into lost revenue, poor user experience, and even security vulnerabilities.

Traditionally, developers relied on monolithic servers or regional data centers to host and deliver content. But that model simply doesn’t scale for modern, global applications.

Requests from users in far-flung regions can experience high latency, packet loss, and long round-trip times to origin servers located across the world.

Enter the Content Delivery Network, or CDN a powerful infrastructure layer designed to solve exactly this problem.

A CDN is a globally distributed network of servers that cache and deliver content from locations physically closer to the end user.

Instead of every image, script, or API call being routed to a centralized origin server, a CDN offloads and serves much of that content from nearby edge nodes dramatically reducing latency, improving load times, and minimizing server strain.

In essence, CDNs bring your app closer to your users regardless of where they are.

While CDNs have traditionally been considered a “frontend” or performance optimization tool, the rise of cloud-native DevOps practices has elevated their role far beyond static asset delivery.

Today, CDNs are tightly woven into the DevOps fabric, helping teams automate deployments, secure applications at the edge, optimize CI/CD pipelines, and even run dynamic logic with edge computing platforms like Cloudflare Workers or AWS Lambda@Edge.

From cache purging after a production push to managing traffic spikes during high-availability events, CDNs enable DevOps teams to build and ship at scale faster, safer, and more efficiently.

In this post, we’ll explore what a CDN is, how it works, and why it’s such a crucial component for DevOps teams today.

We’ll break down its role in performance, scalability, security, and automation, and give you a roadmap for integrating CDN strategies into your DevOps workflows.

Whether you’re deploying globally distributed applications or just starting to scale your infrastructure, understanding how CDNs fit into your DevOps toolkit is key to building fast, resilient, and user-friendly systems. Let’s dive in.

What Is a CDN?

A Content Delivery Network (CDN) is a system of distributed servers strategically placed across multiple geographic locations to deliver digital content more efficiently and reliably to users worldwide.

The primary goal of a CDN is to reduce the distance between the user and the server hosting the requested content, thereby minimizing latency, reducing bandwidth consumption, and improving the overall user experience.

At its core, a CDN works by caching copies of your website’s static and dynamic assets such as images, videos, JavaScript files, stylesheets, and even APIs on edge servers located in data centers around the globe.

When a user makes a request, instead of routing it all the way to the origin server (which might be located halfway across the world), the request is intercepted and fulfilled by the nearest edge node.

This proximity drastically cuts down on the time it takes for content to travel over the internet, leading to faster page loads and smoother interactions.

The CDN’s distributed architecture also offloads significant traffic from your origin servers, protecting them from being overwhelmed during traffic spikes or distributed denial-of-service (DDoS) attacks.

This load distribution means your infrastructure can scale more gracefully, handling sudden surges without crashing or slowing down.

In addition to speeding up delivery, modern CDNs incorporate advanced optimizations such as content compression, image resizing, adaptive bitrate streaming, and HTTP/2 or HTTP/3 protocols all aimed at maximizing performance across devices and network conditions.

Some CDNs even offer edge computing capabilities, allowing developers to run custom code at the edge servers to handle tasks like request routing, authentication, or personalized content delivery with near-instant response times.

CDNs have evolved from simple caching networks into comprehensive platforms that provide not only speed but also security and reliability enhancements.

Features like Web Application Firewalls (WAFs), bot mitigation, SSL/TLS termination, and DDoS protection are commonly integrated into CDN offerings, making them a first line of defense against many types of cyberattacks. For DevOps teams, this means fewer security incidents, less downtime, and more control over traffic flow all while maintaining high availability.

Furthermore, CDNs often provide detailed analytics and logging capabilities, giving teams visibility into traffic patterns, geographic distribution of users, cache hit/miss ratios, and error rates.

This observability allows for continuous optimization of performance and troubleshooting, fitting seamlessly into the DevOps feedback loop.

Another important aspect is the integration of CDNs with modern CI/CD pipelines and infrastructure-as-code tools. With APIs and automation support, cache invalidation, content purging, and configuration updates can be scripted and triggered automatically during deployments.

This reduces manual overhead, prevents serving stale content, and helps maintain synchronization between application releases and cached assets.

Additionally, some CDNs enable granular traffic management through routing rules, geo-blocking, and load balancing across multiple origin servers or even multiple CDNs, offering unprecedented control over how and where your content is delivered.

This multi-CDN approach enhances resilience by eliminating single points of failure and providing failover options during outages.

In essence, a CDN transforms the traditional client-server model into a more decentralized and intelligent network that dramatically improves web performance and reliability. For DevOps practitioners, understanding and leveraging CDNs is essential not only to accelerate content delivery but also to build scalable, secure, and maintainable infrastructure.

As applications grow in complexity and user bases expand globally, CDNs will continue to be a cornerstone technology that enables faster innovation cycles, better user experiences, and stronger operational resilience.

Whether you’re running a startup launching your first website or managing an enterprise-level application serving millions daily, integrating a CDN is no longer optional it’s fundamental to delivering high-quality digital experiences at scale.

CDN in the DevOps Workflow.

1. Faster Deployments.

One of the key benefits of integrating a CDN into the DevOps workflow is the ability to achieve faster, smoother deployments.

By automating cache purging and content invalidation through APIs, DevOps teams ensure that users always receive the latest version of assets immediately after deployment.

This eliminates the common problem of stale or outdated content being served from CDN caches. Furthermore, modern CDNs support edge computing platforms, allowing teams to deploy serverless functions or custom logic at the edge in sync with application releases.

These capabilities enable rapid iteration and continuous delivery without sacrificing performance or reliability.

Automated CDN integration also reduces manual intervention, minimizes deployment errors, and accelerates the overall release cycle, helping DevOps teams maintain high velocity and consistent user experience.

2. Improved Performance & User Experience.

CDNs play a crucial role in enhancing application performance and delivering a superior user experience. By caching content at edge locations closer to users, CDNs reduce latency and speed up page load times, which directly impacts user satisfaction and engagement.

They also support advanced features like image optimization, automatic compression, and HTTP/2 or HTTP/3 protocols that further streamline content delivery.

For DevOps teams, this means fewer performance bottlenecks and smoother application behavior during peak traffic periods. Faster response times improve Core Web Vitals critical for SEO and conversion rates while edge computing enables personalized or dynamic content generation with minimal delay.

Ultimately, integrating CDNs into DevOps pipelines ensures users experience fast, reliable, and seamless interactions, regardless of their geographic location.

3. Scalability Without Extra Ops Overhead.

CDNs allow applications to scale effortlessly without requiring DevOps teams to constantly provision or manage new infrastructure.

By offloading the delivery of static assets and even dynamic content to globally distributed edge servers, CDNs handle high traffic loads automatically.

This is especially valuable during traffic spikes, product launches, or promotional events when demand can surge unpredictably. Because the majority of user requests are served from edge nodes, origin servers experience less strain, reducing the need for costly autoscaling or redundant backend setups.

This hands-off scalability minimizes operational complexity while ensuring performance remains stable under load.

DevOps teams can focus on innovation and delivery, knowing that the CDN layer will absorb much of the heavy lifting in terms of availability and performance at scale.

4. Security at the Edge.

CDNs don’t just improve speed they also enhance security by acting as a protective shield at the network edge.

Many modern CDNs include built-in security features such as Web Application Firewalls (WAFs), DDoS mitigation, bot detection, and SSL/TLS encryption all deployed at edge nodes before traffic reaches your core infrastructure.

This reduces the attack surface and offloads security concerns from your backend systems. CDNs can also enforce access controls, block malicious IPs, and apply rate limiting to prevent abuse. For DevOps teams, this means fewer security incidents, simplified compliance, and reduced reliance on additional third-party security tools.

By securing traffic closer to the user, CDNs enable faster response to threats and ensure uninterrupted service, even during targeted attacks or unusual spikes in malicious activity.

5. Monitoring and Observability.

Monitoring and observability are critical in DevOps, and CDNs provide valuable visibility into traffic, performance, and errors at the edge.

Most CDN providers offer detailed logs, real-time analytics, and metrics such as cache hit ratios, latency, geographic distribution, and HTTP status codes.

This data can be integrated with tools like Grafana, Prometheus, Datadog, or ELK Stack to build dashboards and alerting systems. With insights from the CDN layer, DevOps teams can quickly detect anomalies, troubleshoot issues, and optimize delivery paths before problems impact users.

Observability at the edge also helps correlate performance trends with deployments, regions, or client types. Ultimately, CDN-based monitoring extends your operational awareness beyond the origin, enabling proactive performance tuning and better incident response.

Real-World DevOps Use Cases

• CI/CD + CDN: Automatically purge caches and deploy edge code with GitHub Actions.
• Infrastructure as Code: Manage CDN configs with Terraform (e.g., Cloudflare, Akamai).
• Blue/Green or Canary Deployments: Use CDN routing rules to route traffic to different environments.
• Global Failover: CDNs can reroute traffic to healthy regions in the event of downtime.

CDN is No Longer Just a Frontend Concern.

For years, Content Delivery Networks (CDNs) were viewed primarily as tools for frontend performance mainly caching static files like images, JavaScript, CSS, and fonts.

They were considered the domain of frontend developers and marketing teams focused on improving page load times and SEO.

However, that narrow view is outdated. Today, CDNs have evolved into sophisticated infrastructure platforms that offer far more than just static content delivery.

They now handle dynamic content, API acceleration, edge computing, security enforcement, and traffic management all of which are deeply relevant to DevOps. Modern CDNs operate at a level of intelligence and flexibility that aligns directly with the needs of infrastructure engineers, backend developers, and SREs working in complex, cloud-native environments.

With edge logic capabilities like Cloudflare Workers, AWS Lambda@Edge, and Fastly Compute@Edge, developers can deploy code that runs directly on CDN nodes near users.

This allows for A/B testing, geographic routing, authentication handling, header rewriting, and even personalized content rendering without needing to hit the origin server.

These serverless edge functions are lightweight, fast, and scalable, and they bring application logic closer to the user reducing latency and improving performance. For DevOps, this edge layer adds a new dimension to application architecture.

It decentralizes critical functionality while reducing backend load, improving uptime, and enabling a more responsive user experience.

Security is another area where CDNs have extended their relevance. They now serve as security perimeters, stopping malicious traffic before it reaches your core infrastructure.

CDN providers offer DDoS protection, Web Application Firewalls (WAFs), bot mitigation, rate limiting, and TLS termination all managed through APIs and dashboards that integrate with your CI/CD and infrastructure-as-code workflows.

From a DevOps perspective, this means security enforcement is not just a post-deployment concern it’s a versioned, testable, and deployable part of the stack.

CDNs also support advanced DevOps workflows by providing automation and observability. Cache purging, configuration changes, and edge logic updates can be automated via CI/CD pipelines using tools like Terraform, Ansible, or custom scripts with CDN APIs.

This reduces human error, ensures consistency, and speeds up releases. Meanwhile, CDN logs and metrics give insight into request patterns, error rates, cache performance, and regional traffic, helping teams make data-driven decisions and respond quickly to issues.

These capabilities extend your monitoring and debugging processes beyond your own infrastructure to the edge of the internet.

The rise of microservices, global applications, and multi-cloud strategies further pushes CDNs into the backend domain. For example, CDNs can be used to route traffic across different backend services, balance load across regions, or serve as failover points during outages.

They can even host static frontends while connecting to backend APIs securely via mutual TLS or token-based authentication. In these scenarios, the CDN is no longer a passive layer it’s an active participant in request handling, traffic routing, and even service orchestration.

In short, CDNs have become programmable, intelligent platforms that support the goals of DevOps: speed, reliability, automation, and scalability.

They’re not just about frontend optimization anymore they’re about delivering secure, high-performing applications with minimal operational overhead. For modern DevOps teams, treating the CDN as an extension of the application infrastructure not just a delivery tool is essential for building resilient, efficient systems at scale.

Whether you’re deploying edge logic, securing APIs, or managing multi-region failover, the CDN is now squarely part of the DevOps domain.

Final Thoughts.

In DevOps, we’re always aiming to shift left, improve velocity, and ensure reliability. A CDN isn’t just a performance boost it’s a strategic infrastructure layer that brings your app closer to your users, shields your origin, and scales effortlessly with demand.

Whether you’re deploying a global SaaS app, a mobile backend, or an internal dashboard, CDNs should be part of your DevOps playbook.

Conclusion.

In the world of DevOps, where speed, automation, and reliability are non-negotiable, a CDN is far more than just a performance enhancer it’s a critical part of modern infrastructure.

By caching content closer to users, offloading traffic from origin servers, and adding layers of security and observability at the edge, CDNs help DevOps teams deliver faster, more secure, and more resilient applications.

Whether you’re deploying a static website or a complex microservices-based system, integrating a CDN into your DevOps workflow can significantly improve user experience and operational efficiency.

As the DevOps ecosystem continues to evolve, expect CDNs to play an even greater role in edge computing, serverless functions, and intelligent routing.

If you’re not already using a CDN or if you’re underutilizing the one you have now is the time to level up your stack.

Introduction.

In the early days of system administration, monitoring meant little more than a binary question: “Is the server up or down?” If the answer was “down,” someone got paged; if it was “up,” all was assumed to be well. This kind of basic status checking was sufficient for static, monolithic applications running on physical servers, where change was infrequent and infrastructure was relatively simple.

But in today’s cloud-native, distributed, and fast-moving software environments, this simplistic definition of monitoring no longer holds up.

As organizations adopt DevOps practices to ship features faster, respond to users quicker, and scale more dynamically, the demands placed on monitoring systems have evolved dramatically.

In the DevOps era, monitoring is not just about detecting downtime it’s about providing deep, real-time insight into systems that are constantly changing. Modern applications are composed of hundreds of microservices, running across clusters of ephemeral containers, deployed automatically through CI/CD pipelines, and continuously scaled based on user demand.

Monitoring now plays a central role in ensuring these complex environments remain healthy, performant, and resilient.

It’s a proactive discipline, not just a reactive safety net. From catching performance regressions before users notice, to identifying failed rollouts, to giving developers visibility into their services in production, monitoring has become the backbone of operational excellence in DevOps.

More importantly, DevOps teams don’t just care about if a service is running, but also how it’s running, who it’s impacting, and what it means to the business.

That means monitoring now spans much more than just infrastructure metrics. Teams need to track everything from application-level performance and error rates, to user experience, business KPIs, release health, and security signals.

Traditional monitoring tools focused on individual servers or databases. Modern DevOps monitoring, on the other hand, is all about end-to-end observability integrating logs, metrics, traces, and events to give a full picture of how systems behave under real-world conditions.

At the same time, the speed of modern software delivery has changed expectations. With multiple deployments per day, feature flags, canary rollouts, and auto-scaling infrastructure, the window for identifying and fixing issues has become narrower.

A single unnoticed error in a deployment can ripple across multiple services and user sessions within minutes. That’s why monitoring in DevOps must be real-time, actionable, and automated.

It needs to detect anomalies early, surface meaningful alerts without noise, and empower teams to resolve incidents before they impact customers or ideally, before they even happen.

Another key shift is that monitoring is no longer the sole responsibility of “ops” teams. In high-performing DevOps cultures, everyone shares ownership of reliability.

Developers now build instrumentation into their code, define service-level indicators (SLIs), and use dashboards to debug performance issues.

Site Reliability Engineers (SREs) collaborate with dev teams to define service-level objectives (SLOs) and error budgets. Product managers even use monitoring data to understand user behavior and measure the success of new features. In this way, monitoring has become a cross-functional enabler of better software and smarter decisions.

In this blog post, we’ll explore how monitoring has grown far beyond uptime checks to become an integral part of modern DevOps workflows.

We’ll look at what modern monitoring really involves, why it matters to every stage of the software lifecycle, what tools and metrics DevOps teams rely on, and how it supports a culture of continuous improvement, faster recovery, and higher-quality deployments.

Monitoring is no longer just a technical function it’s a strategic asset, and a critical driver of success in today’s software-driven world.

What DevOps Monitoring Really Means.

When we talk about monitoring in the context of DevOps, we’re not just referring to traditional system health checks or uptime alerts we’re talking about a holistic, data-driven approach to understanding how applications, infrastructure, and user experiences behave in real time.

In a DevOps environment, where development and operations are tightly integrated, monitoring serves as a shared feedback loop between teams. It provides the visibility needed to validate that code changes behave as expected, that infrastructure remains stable under pressure, and that users are having a reliable experience.

This kind of monitoring goes far beyond “is it up?” and ventures into “how is it performing?”, “what’s breaking?”, “who’s affected?”, and “why did this happen?” DevOps monitoring is about delivering actionable insight not just metrics, but meaning.

Unlike the past, where operations teams primarily focused on CPU usage, disk space, and server uptime, today’s DevOps teams monitor services, APIs, containers, user flows, deployments, and business metrics, all in one connected view.

Applications aren’t monoliths anymore they’re built with microservices and deployed across dynamic, containerized platforms like Kubernetes.

That complexity requires observability across layers, where logs, metrics, traces, and events work together to tell a story.

DevOps monitoring means instrumenting code to capture custom metrics, using traces to follow transactions across distributed systems, and defining alerts based on SLIs and SLOs, not just static thresholds.

More importantly, monitoring is no longer an afterthought or something tacked on after deployment. In a DevOps pipeline, it’s part of the shift-left philosophy instrumentation and observability are embedded early, often during development and testing.

Metrics are used during builds to catch regressions, synthetic monitoring runs pre- and post-deploy to detect anomalies, and live telemetry feeds into rollback logic or feature flag systems. In this model, monitoring doesn’t just observe the system it helps automate decisions, improve recovery times, and optimize future releases. It becomes a tool for learning and iteration, not just problem detection.

In a DevOps culture, monitoring also breaks down silos. Developers, SREs, QA engineers, and even product teams rely on the same dashboards to understand system behavior.

Developers can self-serve performance data to diagnose issues without waiting on ops. QA teams can correlate test failures with infrastructure metrics.

SREs can validate SLO adherence and propose capacity improvements. This shared visibility promotes accountability, faster collaboration, and smarter incident response.

By surfacing the right data at the right time to the right people, monitoring transforms from a back-end necessity to a front-line enabler of high-velocity, high-quality software delivery.

So, what does DevOps monitoring really mean? It means embracing continuous visibility as a foundational principle.

It means designing systems with observability in mind, treating telemetry as part of the application, and building feedback loops that enable teams to act quickly, recover faster, and deploy more confidently.

It’s not just a system function it’s a culture, a mindset, and an operational requirement for any team serious about delivering resilient, customer-focused software at scale.

Monitoring Enables the DevOps Pillars.

Monitoring isn’t just a supporting tool in DevOps it actively enables the core pillars that define successful DevOps practices: speed, reliability, collaboration, and continuous improvement.

Without robust, real-time visibility into systems, services, and user experience, these principles can’t function effectively. For example, DevOps is centered around delivering software faster and more frequently, but rapid deployments mean little if teams can’t measure the impact or detect problems early.

Monitoring provides the data and alerts that allow teams to move fast without breaking things. With proper instrumentation, you can instantly see if a new release has introduced latency, broken an API, or triggered an unexpected error spike long before users begin to notice.

Reliability is another pillar that depends heavily on monitoring. It’s not enough for systems to be “up” they need to be healthy, performant, and resilient under changing conditions.

Monitoring supports this by exposing real-time system health, resource usage, error rates, and saturation metrics, enabling teams to catch issues before they cause outages.

It also empowers automated remediation, such as auto-scaling or rolling back a failed deployment, based on live telemetry.

And when something does go wrong, monitoring data is critical for incident response and root cause analysis, helping teams understand what happened, why, and how to prevent it in the future.

Equally important is the collaborative value of monitoring.

In DevOps, where silos are broken down and teams share responsibility for software across the entire lifecycle, monitoring provides a common source of truth.

Developers, operations engineers, SREs, QA testers, and even product managers can all view the same dashboards and alerts, which helps unify understanding and align response.

This transparency improves communication, speeds up troubleshooting, and fosters a culture of shared ownership of performance and reliability.

Monitoring fuels the DevOps mindset of continuous improvement. By collecting and analyzing telemetry over time, teams can uncover trends, refine SLIs and SLOs, and improve both the product and the process. It’s how teams move from reactive firefighting to proactive optimization.

In this way, monitoring is far more than a set of tools it’s a force multiplier for everything DevOps stands for.

What to Monitor Beyond Servers.

In the world of DevOps, monitoring goes far beyond checking server CPU, memory, or disk space. While infrastructure metrics are still important, they only tell part of the story.

Modern systems are built on layers of abstraction, from containers and orchestration platforms to APIs, frontends, and user interactions.

That means DevOps teams must monitor a broad range of components to get a complete picture of system health and performance. For starters, application-level metrics like request rates, error rates, response times, and dependency latency are crucial to understanding how software is behaving in real time. These metrics, often referred to as the “Golden Signals” (latency, traffic, errors, and saturation), help teams quickly detect and diagnose issues that might not be visible from infrastructure alone.

Next, there’s user experience monitoring, which includes synthetic monitoring, real user monitoring (RUM), and tracking front-end performance metrics such as page load time, Core Web Vitals, or mobile responsiveness.

These insights reveal how actual users are experiencing the product and can expose problems that backend metrics might miss. On top of that, business-level metrics like sign-up conversions, cart abandonment rates, or feature adoption can help correlate technical performance with business outcomes, making monitoring valuable not just for engineers, but for product and leadership teams as well.

Additionally, deployment and CI/CD pipeline monitoring is vital. Tracking build success rates, deployment durations, failed releases, and rollback events ensures the delivery process is stable and predictable. Security and compliance monitoring like unusual login patterns, audit log changes, and runtime policy violations are also becoming critical in a DevSecOps culture.

And in containerized environments like Kubernetes, specialized metrics (e.g., pod restarts, node health, cluster state) are essential to understanding the orchestration layer.

In short, effective DevOps monitoring means capturing signals from across the entire stack from code to customer to enable faster diagnosis, smarter decisions, and a better end-user experience.

Monitoring, Observability, and SRE.

While monitoring tells you when something goes wrong, observability helps you understand why. In the DevOps and Site Reliability Engineering (SRE) world, these concepts are deeply connected but serve distinct purposes.

Monitoring typically involves collecting predefined metrics and setting up alerts based on thresholds such as CPU usage over 90% or HTTP error rates above 5%. It’s essential for early detection and response. However, as systems become more distributed and dynamic, it’s not always possible to predict every failure mode. That’s where observability comes in.

Observability focuses on giving teams the tools and telemetry to explore the unknowns, using metrics, logs, and traces to investigate behavior in real time.

SRE teams, in particular, rely on observability to uphold Service Level Objectives (SLOs) and manage error budgets quantitative limits that define how much unreliability a system can tolerate before action must be taken.

This approach shifts the focus from uptime to user experience, enabling smarter trade-offs between velocity and reliability. Tools like Prometheus, Grafana, OpenTelemetry, Jaeger, and Elastic Stack are staples in building this visibility.

In short, observability expands monitoring’s reach, turning raw data into contextual insight crucial for diagnosing issues, optimizing performance, and building systems that are not only available, but truly reliable.

Building Monitoring Into DevOps Workflows.

In modern DevOps, monitoring is not a bolt-on afterthought it’s an essential part of the software delivery lifecycle, embedded into workflows from development to production. By integrating monitoring early, teams can shift observability left, catching performance regressions or misconfigurations before they impact users.

Developers can write custom metrics into code, run synthetic checks in staging, and define alerts as code alongside application logic.

During CI/CD, telemetry data can inform canary analysis, automated rollbacks, and post-deployment validation.

This kind of feedback loop helps teams deploy faster and more safely by making monitoring part of the delivery pipeline, not a separate concern.

Infrastructure teams can manage dashboards, alert rules, and service-level objectives using tools like Terraform, PrometheusRule, or YAML-based configuration, treating them as version-controlled assets. This “Monitoring as Code” approach ensures consistency, auditability, and portability across environments.

When incidents occur, integrations with tools like Slack, PagerDuty, or Opsgenie ensure alerts reach the right people at the right time, complete with logs and trace context for fast triage. Ultimately, embedding monitoring into daily workflows reduces mean time to detection (MTTD), accelerates recovery (MTTR), and empowers all teams to take ownership of reliability.

It’s not just about knowing something went wrong it’s about building systems designed to respond and improve continuously.

• Case: Observability in Kubernetes deployments with Prometheus + Alertmanager

Conclusion

Modern DevOps demands more than just keeping systems online—it requires delivering reliable, high-performing, and user-focused software continuously. Monitoring is the foundation that enables that. By moving beyond uptime and embracing metrics, traces, logs, and user insights, DevOps teams gain the visibility they need to act quickly, deploy safely, and improve confidently.

In the DevOps lifecycle, monitoring isn’t a “post-deploy task”—it’s a first-class citizen that must be integrated from code to production. When done right, it turns data into decisions, alerts into actions, and failures into fuel for growth.

Introduction.

In the ever-evolving world of software development and operations, the way we build, deploy, and scale applications has undergone a dramatic transformation.

The age of monolithic apps, manually configured servers, and weekly releases is giving way to a faster, more flexible, and more resilient paradigm: cloud-native DevOps.

At the heart of this transformation is the Cloud Native Computing Foundation (CNCF) an organization that has become foundational to the modern tech stack.

The rise of DevOps a cultural and technical movement focused on unifying software development (Dev) and IT operations (Ops) was a response to the inefficiencies of traditional software delivery.

Teams needed to move faster, release more often, and recover from failure more reliably. But as applications became more complex, and infrastructures more distributed, it was clear that new tools, standards, and practices were required to meet this growing demand. That’s where cloud-native computing and CNCF come in.

Founded in 2015 under the umbrella of the Linux Foundation, the CNCF was created to support the adoption of cloud-native technologies by fostering open-source projects that simplify infrastructure management and accelerate software delivery.

It all started with one game-changing project: Kubernetes, the now ubiquitous container orchestration platform that Google donated to the CNCF.

Since then, CNCF has grown into a massive ecosystem of over 150 projects ranging from observability tools like Prometheus, to security enforcers like Falco, to CI/CD platforms like ArgoCD and Flux.

But CNCF isn’t just about tools it’s about creating a standardized approach to building systems that are scalable, resilient, and automated by design.

The CNCF landscape empowers DevOps teams to embrace principles like infrastructure as code, GitOps, immutable infrastructure, and declarative configuration. These practices reduce human error, improve reliability, and allow teams to deploy updates multiple times a day with confidence.

Modern DevOps pipelines those that thrive in hybrid and multi-cloud environments are increasingly built on top of CNCF projects.

Whether it’s using Helm to manage Kubernetes applications, OpenTelemetry to collect metrics and traces, or Envoy to route service traffic, CNCF projects serve as the building blocks of highly automated and observable systems.

And since all these projects are open source and vendor-neutral, teams can adopt them without fear of vendor lock-in.

CNCF’s influence extends far beyond its projects. It plays a key role in cultivating best practices through community collaboration, technical documentation, and global events like KubeCon + CloudNativeCon.

It also offers certifications like CKA (Certified Kubernetes Administrator) and CKAD (Certified Kubernetes Application Developer), which help DevOps professionals validate their cloud-native expertise.

Importantly, CNCF also governs the graduation process of its projects, ensuring that only the most mature and stable tools reach “graduated” status trusted by organizations like Netflix, Apple, Shopify, and countless others.

This rigorous maturity model gives engineering leaders confidence when choosing tools to power production systems.

In today’s software landscape, agility and reliability are no longer trade-offs they are expectations.

DevOps teams are now measured by their ability to deliver value rapidly without compromising security or stability. Achieving this balance requires a strong foundation, and CNCF offers just that: a rich, open ecosystem built to support cloud-native development at every stage of the lifecycle.

As we dive deeper into how CNCF tools support and enhance modern DevOps pipelines, keep in mind this core idea: CNCF is not just shaping the future of DevOps it’s enabling it.

What is CNCF?

The Cloud Native Computing Foundation (CNCF) is an open-source software foundation that plays a central role in shaping the future of cloud-native technologies and modern infrastructure.

Launched in 2015 as a part of the Linux Foundation, CNCF was formed with the goal of supporting the growth and adoption of cloud-native computing a new way of designing and managing software applications that are highly scalable, resilient, and adaptable to dynamic environments.

Cloud-native computing refers to an approach where applications are built using containers, organized as microservices, and managed dynamically through orchestration tools like Kubernetes.

CNCF serves as a neutral home for the open-source projects that make this possible, providing governance, funding, community engagement, and technical oversight to ensure long-term sustainability and innovation.

The foundation began with Kubernetes, which Google contributed at the time of CNCF’s inception. Since then, the CNCF has grown into a vast ecosystem of more than 150 active projects, including widely adopted tools like Prometheus for monitoring, Envoy for service proxies, ArgoCD and Flux for GitOps-based continuous delivery, Helm for Kubernetes package management, and OpenTelemetry for observability.

CNCF’s mission goes beyond just hosting code it acts as a collaborative hub for developers, enterprises, vendors, cloud providers, and academics who are committed to building interoperable cloud-native tools.

The foundation ensures that projects are developed in the open, with vendor-neutral governance, allowing for innovation without monopolization.

One of CNCF’s key contributions is the establishment of a graduation process for its projects. This process categorizes projects into three tiers sandbox, incubating, and graduated based on factors like adoption, community size, documentation quality, security practices, and production readiness.

This helps organizations assess the maturity and reliability of a project before integrating it into production systems.

A graduated project is considered stable, trustworthy, and battle-tested by a wide range of organizations in real-world environments. CNCF also offers certification programs, such as CKA (Certified Kubernetes Administrator) and CKAD (Certified Kubernetes Application Developer), which are industry-recognized standards for cloud-native expertise and widely adopted by DevOps professionals and teams.

CNCF hosts several major events and summits, most notably KubeCon + CloudNativeCon, where thousands of developers, architects, SREs, platform engineers, and decision-makers come together to share insights, learn best practices, and discuss the future of the ecosystem.

These events are vital for community-building and serve as a platform for launching and discussing key updates, initiatives, and collaborations.

CNCF also publishes regular end-user technology radars, annual reports, and landscape analyses that help guide organizations on the adoption and impact of emerging technologies.

Another unique contribution from CNCF is the CNCF Landscape, a constantly updated map of tools, platforms, and projects that exist across the cloud-native spectrum.

It categorizes solutions in areas like security, CI/CD, observability, orchestration, networking, and more helping engineers navigate the complex tooling space of cloud-native architecture.

From small startups to global enterprises like Apple, Netflix, and Spotify, organizations across the world are leveraging CNCF-hosted projects to power their cloud-native platforms and DevOps pipelines.

By promoting open standards, strong community collaboration, and high-quality documentation, CNCF lowers the barrier to entry for innovation while avoiding the pitfalls of proprietary lock-in.

As more companies adopt multi-cloud, hybrid-cloud, and microservices strategies, CNCF becomes increasingly relevant not just as a foundation, but as a strategic enabler of modern software infrastructure.

In essence, CNCF is more than just a steward of open-source projects; it’s a powerful movement that’s transforming how software is built and operated at scale.

What is Cloud-Native (and Why DevOps Cares)?

Cloud-native is more than just a buzzword it’s a fundamental shift in how modern software is designed, developed, deployed, and operated.

At its core, cloud-native is an approach to building applications that are specifically designed to run in dynamic, distributed, and scalable environments like public, private, or hybrid clouds. These applications embrace the principles of microservices architecture, where systems are broken down into smaller, independently deployable services that can scale and evolve individually.

Instead of relying on monolithic apps that are difficult to update and deploy, cloud-native systems use containers, typically orchestrated by platforms like Kubernetes, to achieve portability, flexibility, and speed. Infrastructure is declaratively defined using tools like Terraform or Helm, enabling infrastructure as code.

This means environments can be version-controlled, repeatable, and automated ideal for the speed and reliability DevOps demands. Cloud-native systems are built to be resilient, with fault tolerance, self-healing capabilities, and automated recovery baked into the architecture.

This aligns closely with DevOps goals like reducing mean time to recovery (MTTR), increasing deployment frequency, and ensuring consistent environments across development, staging, and production.

For DevOps teams, cloud-native is more than just a trend it’s a solution to many of the longstanding problems in traditional operations and software delivery.

Legacy systems often suffer from long release cycles, fragile environments, and high operational overhead.

In contrast, cloud-native architectures empower teams to automate deployments, testing, monitoring, and scaling through modern CI/CD pipelines and platform APIs.

Tools that support the cloud-native model many of which are maintained by the CNCF help teams adopt practices like GitOps, where infrastructure and application state are managed through Git repositories, ensuring greater traceability and automation.

Observability tools such as Prometheus and OpenTelemetry provide the telemetry needed to monitor highly distributed systems, making it easier to identify performance issues or failures before they impact users.

Cloud-native also promotes ephemeral infrastructure short-lived, reproducible environments that can be provisioned and torn down automatically as needed. This makes experimentation safer and scaling more predictable.

In short, DevOps cares deeply about cloud-native because it delivers the operational capabilities necessary for modern software delivery. It enables small teams to manage complex systems reliably, reduces manual toil through automation, and improves overall agility.

As businesses demand faster time to market, higher uptime, and more secure systems, DevOps teams need cloud-native tools and principles to keep up. Whether you’re deploying hundreds of services a day, running apps across multiple clouds, or building a platform for developers, cloud-native is the architecture that makes it possible and CNCF is the foundation helping bring that architecture to life.
