Amazon SQS
Amazon Simple Queue Service (SQS) is a fully managed message queuing service provided by Amazon Web Services (AWS) that enables decoupling and scaling of microservices, distributed systems, and serverless applications. It allows applications to send, store, and receive messages between software components at any volume without losing messages or requiring other services to be available. SQS offers two types of message queues: Standard queues for maximum throughput and best-effort ordering, and FIFO queues for exactly-once processing and strict ordering.
Developers should use Amazon SQS when building distributed, decoupled applications that need reliable, asynchronous communication between components, such as in microservices architectures, event-driven systems, or batch processing workflows. It is particularly valuable for handling spikes in traffic, ensuring message durability, and improving fault tolerance by allowing services to operate independently, making it essential for scalable cloud-native applications on AWS.
