Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that makes it easy to decouple and scale microservices, distributed systems, and serverless applications. It allows secure, reliable communication between software components by storing messages in queues, offers at-least-once delivery with multiple redundancy across availability zones, and supports standard or FIFO queues to accommodate different messaging patterns.
