Complete Tutorial for Amazon Simple Queue Service (SQS) in AWS

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

1. Getting Started with Amazon SQS

  1. Sign in to AWS Management Console:

    • Go to the AWS Management Console and sign in with your credentials.

  2. Navigate to Amazon SQS:

    • In the AWS Management Console, search for "Amazon SQS" and select it.

  3. Create a Queue:

    • Click on "Create Queue" and provide a name for your queue.

    • Choose the appropriate queue type (Standard Queue or FIFO Queue) based on your requirements.

    • Configure additional settings such as visibility timeout, message retention period, and dead-letter queue (optional).

    • Click "Create" to create the queue.

2. Sending Messages to an SQS Queue

  1. Using AWS Management Console:

    • Go to the SQS console and select the queue you created.

    • Click on "Send Message" and enter the message body.

    • Click "Send" to send the message to the queue.

  2. Using AWS SDK:

    • Install the AWS SDK for your preferred programming language (e.g., Python, Java, C#).

    • Use the SDK to send messages to the queue.

Example (Python):

python
import boto3

# Create an SQS client
sqs = boto3.client('sqs')

# Send a message to the queue
queue_url = 'https://sqs.us-east-1.amazonaws.com/123456789012/my-queue'
response = sqs.send_message(
    QueueUrl=queue_url,
    MessageBody='Hello, World!'
)
print(response)

3. Receiving Messages from an SQS Queue

  1. Using AWS Management Console:

    • Go to the SQS console and select the queue.

    • Click on "Receive Messages" and specify the number of messages to receive.

    • Click "Receive" to retrieve the messages from the queue.

  2. Using AWS SDK:

    • Use the SDK to receive messages from the queue.

Example (Python):

python
import boto3

# Create an SQS client
sqs = boto3.client('sqs')

# Receive messages from the queue
queue_url = 'https://sqs.us-east-1.amazonaws.com/123456789012/my-queue'
response = sqs.receive_message(
    QueueUrl=queue_url,
    MaxNumberOfMessages=1
)
print(response)

4. Deleting Messages from an SQS Queue

  1. Using AWS Management Console:

    • Go to the SQS console and select the queue.

    • Click on "Delete Messages" and specify the message IDs to delete.

    • Click "Delete" to remove the messages from the queue.

  2. Using AWS SDK:

    • Use the SDK to delete messages from the queue.

Example (Python):

python
import boto3

# Create an SQS client
sqs = boto3.client('sqs')

# Delete messages from the queue
queue_url = 'https://sqs.us-east-1.amazonaws.com/123456789012/my-queue'
response = sqs.delete_message(
    QueueUrl=queue_url,
    ReceiptHandle=response['Messages'][0]['ReceiptHandle']
)
print(response)

5. Cleaning Up Resources

  1. Delete the Queue:

    • Go to the SQS console and select the queue.

    • Click on "Delete Queue" and confirm the deletion.

  2. Delete IAM Roles and Policies:

    • If you created any IAM roles or policies for SQS, delete them to avoid unnecessary costs.

Uncontrolled form input in React-JS

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
