Organizations are looking for ways to scale their services, systems and applications, thanks to the increasing use of technology and services. AWS offers a Simple Queue Service (SQS) to assist these organizations. Amazon Simple Queue Service (Amazon SQS), which provides a hosted queue that is secure, reliable, and accessible, facilitates the integration and decoupling of distributed software systems and components. You find that interesting? Let’s make it even more interesting by learning about Amazon Simple Queue Services features and how to get started. So, let’s begin!
Amazon QS Overview
Amazon SQS is a message queuing system that can be used to decouple and scale microservices, distributed systems and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented midware and allows developers to focus on differentiating work. This service allows you to send, store, or receive messages between software components at any volume without any message loss. It also does not require other services to be available.
Amazon SQS also provides common constructs such as dead-letter queues or cost allocation tags. It offers a web services API that can easily be accessed with any programming language that supports the AWS SDK. There are two types of message queues available in SQS.
First, standard queues. This allows for maximum throughput, best-effort order placement, and at most one delivery.
Secondly, SQS FIFO queues. This ensures that messages are processed in the exact same order as they were sent.
Amazon SQS: Benefits
First, you can control who can send and receive messages in SQS.
The Server-side encryption feature (SSE) allows you to transmit sensitive data using the queue protection feature. This is done with keys managed in AWS Key Management Service.
For safety, Amazon SQS stores send messages to multiple servers. It also has redundant infrastructure to provide highly-concurrent access and high availability for creating and consuming messages.
Fourth, Amazon SQS is able to process each buffered request separately, scaling transparently for handling load increases without any provisioning.
It also has the ability to lock messages during processing. This allows multiple users to receive and send messages simultaneously.
SQS has:
Second, you don’t need to install, configure, or acquire messaging software.
Finally, there is no need to spend time on maintenance and build-out.

You can then use Amazon SQS to transmit any volume of data at any throughput without losing messages or requiring that other services be available. It allows you to decouple application components so that they can run independently, thus increasing the overall fault tolerance of your system.
Amazon SQS also supports AWS cloud to dynamically scale according to demand. It scales elastically with your applications and can store unlimited messages per queue.
Amazon SQS, Amazon MQ and Amazon SNS are different
Amazon SQS, Amazon SNS are queue and topic services that can be scaled easily, do not require the creation of message brokers, and are highly scalable. These services are ideal for new applications that have access to simple APIs and almost unlimited scalability. Amazon MQ is a message broker service that provides compatibility with many message brokers. This service is ideal for migrating applications from existing messaging brokers based on compatibility with protocols or APIs.
What are the main features of Amazin QS?
This service has many unique features. Some of these features include:
1. Queue types
Amazon SQS provides two queue types for different application requirements:
1. Standard Queues
Standard queues can support unlimited transactions per second (TPS), per API action. This means that the message is delivered only once. Sometimes, however, more than one copy of the message is delivered. The message must be delivered in a different order than the original.
Further, you can use standard message queues in scenarios like:
First, decoupling live user request from intensive background work.
Second, assigning tasks to multiple worker nodes. This allows for processing large numbers of credit card validation requests.
Batching messages for future processing is another option. Multiple entries can be added to a single database by scheduling.
2. FIFO Queues
FIFO queues can handle up to 300 messages per minute. FIFO queues can handle up to 3,000 messages per minute if there is batching of 10 messages. You can also enable high throughput mode on Amazon SQS console to allow for higher throughput. This will allow you to process up to 30,000 messages per minute with batching. This means that the message is sent once and remains accessible until the consumer deletes it. The order in which messages are received and sent is First-In, First-Out.
FIFO queues can be used to enhance messaging between applications in cases where the order of operations or events is crucial or where duplicates are prohibited. Take this example:
Firstly, ensure that commands entered by the user are executed in the correct order.
Secondly, you can display the correct product price by submitting price modifications in the right place.
Finally, students cannot enroll in a course without registering for an account.
2. Functionality
1. Unlimited messages and queues
You can create unlimited Amazon SQS queues and send unlimited messages to any region.
2. Payload size
Message payloads may contain up to 256KB text in any format. Each 64KB chunk of the payload is charged as 1 r
