AWS EventBridge

A serverless event bus that connects application data from your own apps, SaaS, and AWS services to streamline event-driven architectures.

EventBridge eliminates the friction of point-to-point integrations by using a central bus to route data between sources like Zendesk, Shopify, or custom microservices. It handles ingestion, delivery, security, and authorization without requiring you to manage infrastructure. You define declarative rules to filter events and route them to over 28 AWS targets (including Lambda, SQS, and Step Functions). Features like the Schema Registry and Pipe support ensure your decoupled systems communicate with strict type safety and minimal glue code.
