Application Integration & Messaging

A fully managed front door for your APIs — routing, throttling, authentication, and request/response transformation, without running your own API layer.

A fully managed message queue for decoupling services — buffering work between producers and consumers so neither depends on the other being available at the same instant.

Fanning a single event out to many subscribers with SNS, and routing events between many producers and consumers based on content with EventBridge.

Real-time, ordered, replayable data streaming at massive scale — for when you need many consumers reading the same continuous flow of events, not just one-time delivery.
