INTRODUCTION

Amazon SQS (Simple Queue Service) Dead Letter Queues (DLQs) are a feature that helps manage message processing failures in your messaging workflows. When messages in a standard SQS queue fail to be processed successfully after a certain number of attempts, they can be automatically sent to a DLQ.

DLQs can also be monitored for metrics like the number of messages and errors, which can help you maintain the health of your messaging system.

How To Works

For this task, we will establish a primary testing queue along with a Dead-Letter Queue.

1. Navigate the SQS service , and Click on the Create queue button.

2. Click the standard and , enter the queue name.

3.Message retenation period : Enter 14 Days.

4. Then next , click on create Queue button.

5. Once you click on Create Queue, you will get a success message. 

6. Next, we’ll set up a Primary Queue using all default options and link it to the previously created queue.

7. Click on Create queue button and , Select the standard and , enter some other queue name.

9. Select the Dead-letter queue and click on enable.

10. Choose queue : Select My queue arn , and select the Maximum receives : Enter 1

11. Click on the Create queue button. 

12. We are now going to send a message from our Testing Queue.Click on Send and receive messages button.

3. Send message 

• Message body : Enter ” Hellow my first message”

Now click on Send message .Once you have sent a message, you get an acknowledgment .Now we can see that Messages available changes to 1.

Now, to get all the messages we have sent, click on Poll for messages in the Receive messages section.We can now see the message column has been filled with the messages .

Now, click the message to open and read its body. 

Now, click on poll for messages again. You will see the messages available will become 0.

we received the message once and added the received count to 1 limit to the Queue 2 this time the message we polled has been moved into the My -queue. Now, let’s navigate to the Queue Dashboard and check the message available count in both queues. 

You might find the message availability in My-Queue is 1 and Queue-2nis 0.

Now click on My-Queue to check the message and click on Send and receive messages.

Now, to get the message, click on Poll for messages in the Receive messages section. Additionally, take note of the receive count which is 2 that means it is same message which we received on Queue-2.

Click on the message to view its body and confirm that it is identical to what we sent earlier.

CONCLUSION

You have successfully set up a dead-letter queue.

Its features, such as message queuing, FIFO (First-In-First-Out) ordering, and the ability to integrate with other AWS services, make SQS a versatile tool for managing workloads in cloud environments. However, organizations should consider best practices for message handling, monitoring, and cost management to fully leverage SQS’s capabilities. As businesses increasingly move towards cloud-native solutions, SQS stands out as a key component for efficient and scalable application development.

Amazon Route 53 is a powerful Domain Name System (DNS) web service that helps route users to applications by translating domain names into IP addresses. One of its fundamental features is the concept of hosted zones, which are essential for managing DNS records for your domains.

What is a Hosted Zone?

A hosted zone is a container for records that define how you want to route traffic for a domain and its subdomains. It serves as a place to manage DNS records for your domain. There are two types of hosted zones:

1. Public Hosted Zones: Used for domains that need to be accessible on the internet. They contain DNS records that can be queried by anyone on the internet.
2. Private Hosted Zones: Used for domains that should only be accessible within an Amazon Virtual Private Cloud (VPC). They contain records that are only visible to resources within that VPC.

In this guide, I will show you how to create Route 53 hosted zones.

STEP1:Navigate the Route 53 and select the Create hosted zones.

Create a public Hosted Zone .

STEP2: Create a Hosted Zone, Enter the Domain name and select the public hosted zone.

STEP3:Now click the create hosted zone button.

STEP4:You will see the 2 record sets have been already created. One is NS type another is SOA type. From here you can create the hosts of your domain.  

Create a Private Hosted Zone.

STEP5:Select the create hosted zone button, Enter the domain name and select the Private hosted zone.

STEP6:Then, select the Region and VPC (default).

STEP7:Click the Create hosted zone.

STEP8:You can see 2 record sets have been already created. One is NS type another is SOA type. From here you can create the hosts of your domain.  

CONCLUSION

Finally, you create the Route53 Hosted zone. Creating a hosted zone in Amazon Route 53 is an essential step in managing DNS for your domains, whether they are publicly accessible or used within private networks. By following this guide, you’ve learned how to create both public and private hosted zones, configure DNS records, and update your domain registrar to route traffic through AWS.

A Brief Explanation of IAM

IAM, or Identity and Access Management, serves as the guardian of access within the AWS ecosystem. IAM is a framework of policies and technologies that ensures the right individuals have the appropriate access to technology resources within an organization. It involves managing user identities, roles, and permissions to secure access to systems, applications, and data.

Crucial IAM Elements:

• User.
• Groups.
• Roles.
• Policies.

USER: IAM users help manage access to AWS resources securely, and you can set permissions for them individually or in groups.

GROUPS: Collections of users, streamlining permission management by assigning policies to a group rather than individual users.

ROLES:IAM roles are a feature of AWS Identity and Access Management (IAM) that allow you to grant specific permissions to entities (like users, applications, or services) without needing to create permanent IAM users.

POLICIES: Access control rules that define what actions are allowed or denied. These can be attached to users, groups, or roles.

Step-by-Step Instructions

Use this sequential guide to create IAM groups and users.

STEP1:Log in to AWS Console as a root user, Navigate to the IAM Dash board.

STEP2: Go to the left navigation pane click on user and select the “create user“

STEP3:Next, enter the user name and tick the Provide user access to the AWS management console.

STEP4:select the IAM user and also autogenerated password.

STEP5:Then click on next button.

STEP6:select the add user to the group.

STEP7:Next you will create the user group.

STEP8:Enter the user group name and click the any permission policies (For example : I select the S3 policies.

STEP9:Then , next select create user group.

STEP10:Next , you will see this page, Copy the link and paste the browser.

STEP11:You see this following page. click the sign in.

STEP12:Then it will ask to create new password as we autogenerated password.

STEP13:Then open the AWS IAM Console.

STEP14:Now you will use only S3 bucket in IAM console. because, permission polices only allowed to S3 bucket.

If you try some other services. You will see the this type of page.
