Amazon SQS

SQS will be helpful for usage in terms of creating a Async flow to your system with though high usage but not high importance data sent to SQS.Whereas in cases where we need to manage messages and auditing of them sent to SQS , also to monitor performance of system integrated with SQS , in such cases SQS would not be a preferred option.Best thing about SQS is that it is quite easy to implement and manage which makes it quick and hassle free.

SQS can be used when you need to create an architecture with asynchronous operations and when you are building many microservices that need to exchange messages.
It is different from SNS which allows you to broadcast messages to various targets

If you are looking to build something that just requires a simple queue service (as the name implies) this is great for it. You might look elsewhere though if you get into more complicated needs. This is also very well suited if you are already using other services with AWS and intend to fully build whatever you are building in AWS. If you are looking for a mixed environment -- SQS is not for you.

While we use AmazonSimple Queue Service (SQS) in our serverless applications, it would be a great option to handle queue management for any internet-connect application. It provides the most benefit in situations where your application or service must maintain mission-critical queue of messages or jobs. If you're already using other AWS services you will find the greatest benefit.

We needed an application where we could communicate between asynchronous modules, and we needed a reliable solution where we could upload data under the HIPPA compliance, and Amazon SQS is the best fit.

Amazon SQS is great for decoupling micro-services. Decoupling services can result in smaller services that are easier to understand and independently deployable, improving developer velocity. It is also easy to scale tiers independently. SQS is especially great if message order and exactly-once processing are not essential. If you have these requirements, you can still try FIFO queues, but their throughput is limited.

If you are trying to handle a large messaging queue to your customer base, specifically with email marketing notifications in mass quantities, this is a great tool. If you’re doing more personality, one-off messaging then this is not the ideal service.
