Learn about how first-in-first-out FIFO queues help make sure the messages you send to systems are published in the correct order.

SQS enables web service applications that help to quickly and reliably queue messages. These messages have one component in their application that generates only when to be consumed by another component. Therefore, the queue is a temporary repository for messages and these messages are awaiting processing. So, Once these messages are processed, the messages also get deleted from the queue. A queue is a place where you can store your messages until they are extracted from the queue or expired. The applications which are running in the cloud will be distributed across the different servers they need to communicate with each other. SQS standards for Simple Queue Service offer asynchronous massaged-based communication between two services.

Let's look at a website that generates a Meme. Suppose the user wants to upload a photo and wants to convert into Meme. User uploads a photo on a website and website might store a photo in s3. As soon as it finished uploads, it triggers a Lambda function. Lambda analyzes the data about this particular image to SQS, and this data can be "what the top of the meme should say", "what the bottom of the meme should say", the location of the S3 bucket, etc. The data sits inside the SQS as a message.

This post is contributed by Robin Salkeld, Sr. Software Development Engineer. Amazon SQS is a fully managed message queuing service that makes it easy to decouple and scale microservices, distributed systems, and serverless applications. Asynchronous workflows have always been the primary use case for SQS. Using queues ensures one component can keep running smoothly without losing data when another component is unavailable or slow. We were surprised, then, to discover that many customers use SQS in synchronous workflows.
