Amazon Simple Queue Service Queue Icon

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that makes it easy to decouple and scale microservices, distributed systems, and serverless applications. It allows different parts of your application to communicate asynchronously, making it more robust and scalable. Think of it like a mailbox: one part of your application puts messages (tasks) into the queue, and another part picks them up and processes them at its own pace. This prevents bottlenecks and allows independent scaling of different components.
