In our last tutorial, we studied Amazon SNS. Here, in this AWS SQS Tutorial, we will explore what is Amazon SQS (Simple Queue Service). Moreover, we will discuss the benefits of Amazon Simple Queue Service and companies using Amazon SQS.

So, let’s start the AWS SQS Tutorial.

What is Amazon SQS (Simple Queue Service)?

AWS SQS (Amazon Simple Queue Service) is a service which helps to align the message. Moreover, it also helps to enable the user to separate and scale microservices, distributed system, and serverless applications.

Amazon SQS makes it easy to manage the operating message-oriented middleware and enhances the developers to focus on their work. Amazon Simple Queue Service works at any volume without losing the message or requiring other services to be available.

It helps to send, store, and receive messages between software components. AWS SQS can start with the help of the tools such as Amazon Console, command line interface, and SDK.

In Amazon SQS there are two types of queues which are Standard Queue and AWS SQS FIFO. Standard queue offers at least one delivery and maximum throughput. The FIFO queues guarantee that the processed message takes place only once in the first in first out basis.

Benefits of Amazon Simple Queue Service

These are the 4 benefits of Amazon SQS, let’s discuss them:


Amazon Simple Queue Service Tutorial – Benefits

a. Eliminate Administrative Overhead

AWS manages all in progress operations and underlying infrastructure required to produce an extremely accessible and scalable message queuing service.

With AWS SQS, there’s no direct value, no ought to acquire, install, and assemble messaging package, and no long build-out and maintenance of supporting infrastructure.

Amazon SQS queues are dynamically created and scale automatically, therefore, you’ll be able to build and grow applications quickly and with efficiency.

b. Reliably Deliver Messages

Use AWS SQS to transmit any volume of data, at any level of output, while not losing messages or requiring alternative services to be accessible. Amazon SQS helps you to decouple application parts in order that they run and fail severally, increasing the fault tolerance of the system.

Multiple copies of each message area unit hold on redundantly across multiple accessible zones in order that they’re out there whenever required.

c. Keep Sensitive Information Secure

You can use Amazon SQS to exchange sensitive data between applications using server-side secret writing (SSE) to inscribe every message body.

The AWS SQS compass point integration with AWS Key Management Service (KMS) permits you to centrally manage the keys that defend SQS messages together with keys that defend your alternative AWS resources.

AWS KMS logs each use of your encryption keys to AWS CloudTrail to assist meet your restrictive and compliance wants.

d. Scale Elastically and Cost-Effectively

AWS SQS leverages the AWS cloud to dynamically scale supported demand. Amazon SQS scales elastically together with your application. Therefore, you don’t have to worry regarding capability designing and pre-provisioning.

There’s no limit to the number of messages per queue, and commonplace queues offer nearly unlimited output. Prices area unit supported usage that provides important value saving versus the “always-on” model of self-managed electronic messaging middleware.

Companies Using AWS SQS

Following are the popular companies who use Amazon Simple Queue Service:

  • BMW
  • NASA
  • EMS Driving Fuel IQ
  • Capital One
  • Redbus
  • OyesterChange Healthcare

AWS SQS Tutorial – Queue & Functions

a. Standard Queue

  • It has a benefit of supporting an ample amount of transactions per second per API action.
  • As the message is delivered on at a time but at the same time, it delivers more than one copy of a message.
  • It may happen that the message delivered is in the different order from the source in which they were sent.

b. FIFO Queue

  • It has a high throughput which can send 300 messages per second which include 300 send, receive, and delete operation per second.
  • The message is not duplicated it is stored with the customer until and unless customer deletes it.
  • The messages are treated in first in first out order as the message sent and received is strictly preserved.

So, this was all about AWS SQS Tutorial. Hope you like our explanation.


Hence, we studied that the AWS SQS helps to send the unlimited number of messages and in any region. Message payloads consist of 256KB of text which can be in any format. If the text is of the size larger than this extended client library for Java Programming can use.

Send and read messages can be done simultaneously. Amazon SQS queries can share anonymously or with some specific AWS accounts. The sharing can restrict for some time and by the IP address.

The contents of the message of AWS SQS can secure using keys managed by the AWS Key Management Service. This helps a lot for the user to use SQS in an efficient manner. Still, have a query, feel free to ask in the comment box.
