What is Amazon SQS?

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS offers two types of queues: Standard queues for maximum throughput and best-effort ordering, and FIFO queues for guaranteed ordering and exactly-once processing. It eliminates the complexity and overhead of managing message-oriented middleware. SQS provides server-side encryption, dead-letter queues for handling message processing failures, and integration with AWS services. It scales elastically and provides reliable message delivery.
