Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, integrated Software-as-a-Service (SaaS) applications, and AWS services. EventBridge provides a stream of real time data from event sources like Pagerduty, Datadog, and Zendesk. It routes that data to AWS Lambda. To build applications that respond in real-time to all your data sources, you can set up routing rules. EventBridge makes it easy for you to create event-driven apps. It handles event ingestion, delivery, authorization, security, and error handling. Your applications will become more interconnected by events. You need to spend more time finding and understanding the structure of events in order to write code that reacts to them.
