Amazon SQS: Amazon Simple Queue Service (AWS 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 middle ware and empowers developers to focus on differentiating work.
Using SQS, you can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available Get started with SQS in minutes using the AWS console, Command Line Interface or SDK of your choice, and three simple commands.
SQS offers two types of message queues. Standard queues offer maximum throughput, best-effort ordering, and at-least-once delivery. SQS FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.
Amazon SQS Benefits
Sensitive data secure
To exchange sensitive information between the applications with SSE (server-side encryption) to encrypt each message. The AWS KMS (Key Management Service) allows managing the keys to protect SQS messages along with keys that protect other AWS resources. The AWS CloudTrail is used to keep logs of AWS Key Management Service.
Scale elastically and cost-effective
The Amazon SQS allows the AWS cloud to dynamically scale. The SQS scales elastically with application no need to worry about planning and pre-provision. There is no limit to the messages in the queue and the standard queues allow unlimited messages. The cost is based on the significant cost saving vs “always-on” model for self-managed message middleware.
Reliably deliver messages
To transmit any volume of data, at any level, without losing messaging or other services to be available use Amazon SQS. The Amazon SQS allows you to decouple the application components so they can independently run or fail and increases the fault tolerance of the system.
Eliminates administrative overhead
Amazon Web Services manages all the operations, the infrastructure needed to provide highly available and scalable message queuing. Within SQS no need to acquire, install or configure messaging software and maintenance for supporting infrastructure. The SQS queues are automatically scaled and dynamically created that helps to build and grow applications efficiently and quickly.
