Amazon SQS

Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. Amazon SQS offers two types of message queues. Standard queues offer maximum throughput, best-effort ordering, and at-least-once delivery. FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.

Amazon SQS makes it simple and cost-effective to decouple the components of a cloud application. You can use Amazon SQS to transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be available. Amazon SQS lets you offload the administrative burden of operating and scaling a highly available messaging cluster, while paying a low price for only what you use.
