Amazon SQS

Amazon Simple Queue Service (SQS) is a fully managed message queue that decouples the components of a distributed system. Producers send messages to a queue and consumers process them independently, so a spike or failure in one component does not overwhelm another — the canonical example of a loosely coupled, resilient architecture.
