SQS queue concept in AWS - Mini Project: Build & Apply

Create and Configure an AWS SQS Queue

📖 Scenario: You are setting up a simple messaging system in AWS to decouple parts of an application. You will create an SQS queue, configure its visibility timeout, and enable dead-letter queue support.

🎯 Goal: Build an AWS CloudFormation template that creates an SQS queue named MyQueue, sets its visibility timeout to 30 seconds, and configures a dead-letter queue named MyDeadLetterQueue with a max receive count of 5.

📋 What You'll Learn

Create an SQS queue named MyQueue

Create a dead-letter SQS queue named MyDeadLetterQueue

Set the visibility timeout of MyQueue to 30 seconds

Configure MyQueue to use MyDeadLetterQueue as its dead-letter queue with a max receive count of 5

💡 Why This Matters

🌍 Real World

SQS queues are used to decouple microservices and handle asynchronous message processing reliably.

💼 Career

Cloud engineers and DevOps professionals often create and configure SQS queues to build scalable, fault-tolerant systems.

1

Create the main SQS queue resource

Create an AWS CloudFormation resource named MyQueue of type AWS::SQS::Queue with no properties yet.

AWS

# Your code here to create the MyQueue resource

Need a hint?

Use the Resources section and define MyQueue with the correct type.

2

Create the dead-letter queue resource

Add an AWS CloudFormation resource named MyDeadLetterQueue of type AWS::SQS::Queue below MyQueue.

AWS

Resources:
  MyQueue:
    Type: AWS::SQS::Queue
  # Your code here to create MyDeadLetterQueue resource

Need a hint?

Define MyDeadLetterQueue as another SQS queue resource.

3

Set visibility timeout for MyQueue

Add a Properties section to MyQueue and set VisibilityTimeout to 30 seconds.

AWS

Resources:
  MyQueue:
    Type: AWS::SQS::Queue
    # Your code here to add Properties with VisibilityTimeout 30
  MyDeadLetterQueue:
    Type: AWS::SQS::Queue

Need a hint?

Use the Properties key under MyQueue to set the timeout.

4

Configure dead-letter queue for MyQueue

Add a RedrivePolicy property under MyQueue Properties that references MyDeadLetterQueue ARN and sets maxReceiveCount to 5.

AWS

Resources:
  MyQueue:
    Type: AWS::SQS::Queue
    Properties:
      VisibilityTimeout: 30
      # Your code here to add RedrivePolicy
  MyDeadLetterQueue:
    Type: AWS::SQS::Queue

Need a hint?

Use !GetAtt MyDeadLetterQueue.Arn to get the ARN of the dead-letter queue.
