Introduction

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware, and empowers developers to focus on differentiating work.

In this article, we will provide a step-by-step guide to creating an AWS SQS Queue. We will cover the necessary commands and code snippets to get you up and running quickly.

Prerequisites

Before you begin, you will need the following:

• An AWS account
• An IAM user with the necessary permissions to create an SQS queue
• The AWS CLI installed and configured

Step 1: Create an SQS Queue

The first step is to create an SQS queue. You can do this using the AWS CLI or the AWS Management Console.

Using the AWS CLI

To create an SQS queue using the AWS CLI, run the following command:

aws sqs create-queue --queue-name <QUEUE_NAME>

Replace <QUEUE_NAME> with the name of the queue you want to create.

Using the AWS Management Console

To create an SQS queue using the AWS Management Console, follow these steps:

1. Log in to the AWS Management Console and navigate to the SQS service.
2. Click the “Create Queue” button.
3. Enter a name for the queue and click “Create Queue”.

Step 2: Set Permissions

Once you have created the queue, you need to set the necessary permissions. This can be done using the AWS CLI or the AWS Management Console.

Using the AWS CLI

To set the permissions for the queue using the AWS CLI, run the following command:

aws sqs set-queue-attributes --queue-url <QUEUE_URL> --attributes '{"ReceiveMessageWaitTimeSeconds": "20"}'

Replace <QUEUE_URL> with the URL of the queue you want to set the permissions for.

Using the AWS Management Console

To set the permissions for the queue using the AWS Management Console, follow these steps:

1. Log in to the AWS Management Console and navigate to the SQS service.
2. Select the queue you want to set the permissions for.
3. Click the “Permissions” tab.
4. Click the “Add Permission” button.
5. Enter the necessary permissions and click “Save”.

Step 3: Send Messages

Once you have set the permissions for the queue, you can start sending messages. This can be done using the AWS CLI or the AWS Management Console.

Using the AWS CLI

To send a message to the queue using the AWS CLI, run the following command:

aws sqs send-message --queue-url <QUEUE_URL> --message-body '{"message": "Hello World!"}'

Replace <QUEUE_URL> with the URL of the queue you want to send the message to.

Using the AWS Management Console

To send a message to the queue using the AWS Management Console, follow these steps:

1. Log in to the AWS Management Console and navigate to the SQS service.
2. Select the queue you want to send the message to.
3. Click the “Send Message” button.
4. Enter the message and click “Send Message”.

Step 4: Receive Messages

Once you have sent the message, you can start receiving messages. This can be done using the AWS CLI or the AWS Management Console.

Using the AWS CLI

To receive a message from the queue using the AWS CLI, run the following command:

aws sqs receive-message --queue-url <QUEUE_URL>

Replace <QUEUE_URL> with the URL of the queue you want to receive the message from.

Using the AWS Management Console

To receive a message from the queue using the AWS Management Console, follow these steps:

1. Log in to the AWS Management Console and navigate to the SQS service.
2. Select the queue you want to receive the message from.
3. Click the “Receive Message” button.
4. Select the message and click “Receive Message”.

Step 5: Delete Messages

Once you have received the message, you can delete it. This can be done using the AWS CLI or the AWS Management Console.

Using the AWS CLI

To delete a message from the queue using the AWS CLI, run the following command:

aws sqs delete-message --queue-url <QUEUE_URL> --receipt-handle <RECEIPT_HANDLE>

Replace <QUEUE_URL> with the URL of the queue you want to delete the message from, and <RECEIPT_HANDLE> with the receipt handle of the message you want to delete.

Using the AWS Management Console

To delete a message from the queue using the AWS Management Console, follow these steps:

1. Log in to the AWS Management Console and navigate to the SQS service.
2. Select the queue you want to delete the message from.
3. Click the “Receive Message” button.
4. Select the message and click “Delete Message”.
