Amazon Simple Queue Service…

Amazon Web services hold many services in its package. These services are widely used around the globe to lessen the amount of burden caused due to managing them. One such managed service is SQS, lets get a know-how of the benefits it has to render us.

What is SQS service?

Amazon SQS is a tool in the Message Queue category of a tech stack.

Amazon SQS

Amazon Simple Queue Service supports tasks that process asynchronously. Instead of one application having to invoke another application directly, the service enables an application to submit a message to a queue, which another application can then pick up at a later time.

In simple words, SQS can be defined as a service where one service sends messages in a queue and another service receives those messages. It can be used for a whole range of purposes.

Why SQS?

Queues can be used to handle malfunctions in the scalability of services. when a service depends on another service that can not scale to the same level. Having a queue between A and B is useful in such situations because the queue can handle peak demand from A, and send messages at a slower rate with which B can cope. Where A will send a message directly to B this may cause an issue if B System gets failure, corrupt, or lost data during loading data to solve this we are gone using SQS Service where this acts as Intermediator which stores data and sends to B so even B gets failure until that system set up this will be stored in SQS than sent to B.

There are two Queues in SQS Standard and FIFO SQS

Companies Using SQS

Lots of companies reportedly use Amazon SQS in their tech stacks, including Pinterest, Amazon, BMW, NASA, EMS Driving Fuel IQ, Capital One, Redbus, Lyft, and many more.

I mentioned some companies case study below,

Recently Started Integrating SQS in their companies


By implementing a serverless strategy on AWS, KreditBee has increased its monthly loan disbursement by 25 times over a two-year period.

Expedia Group

Expedia Global Payments migrated a legacy system from Microsoft SQL Server to Aurora PostgreSQL, cost-effectively scaling to meet traffic and delivering near-real-time data to its users and internal teams.

Top Companies Using SQS and their success stories


NASA Established in 1958, the National Aeronautics and Space Administration (NASA) has been working around the world — and off of it — for almost 60 years, trying to answer some basic questions: What’s out there in space? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?


Use Cases


In building the solution, ManTech International took advantage of the following AWS services:

Amazon Elastic Compute Cloud (Amazon EC2), which provides secure, resizable compute capacity in the cloud. This enables NASA to scale up under load and scale down during periods of inactivity to save money, and pay for only what it uses.

The Challenges

The Benefits

The travel agency anticipates expanding the AWS solution to include Amazon Simple Notification Service (Amazon SNS) and Amazon Simple Queue Service (Amazon SQS) for monitoring, alerts, and intercommunication. SQS helps to provide more security by securing the sensitive data of users of redBus. In addition, the increasing amount of users of redBus are benefitted from the reduction in latency provided by SQS.

Benefits and features of SQS Service

Server-side encryption (SSE): It lets you transmit sensitive data by protecting the contents of messages in queues using keys managed in AWS Key Management Service (AWS KMS).

Availability: Amazon SQS uses redundant infrastructure to provide highly-concurrent access to messages and high availability for producing and consuming messages.

Scalability: Amazon SQS can process each buffered request independently, scaling transparently to handle any load increases or spikes without any provisioning instructions.

Reliability: Amazon SQS locks your messages during processing so that multiple producers can send and multiple consumers can receive messages at the same time.
