Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, Software-as-a-Service (SaaS) applications, and AWS services. EventBridge delivers a stream of real-time data from event sources, such Zendesk, Datadog, or Pagerduty, and routes that data to targets like AWS Lambda. You can set up routing rules to determine where to send your data to build application architectures that react in real time to all of your data sources. EventBridge allows you to build event-driven architectures, which are loosely coupled and distributed. This improves developer agility as well as application resiliency. EventBridge makes it easy to build event-driven applications because it takes care of event ingestion and delivery, security, authorization, and error-handling for you. EventBridge leverages the CloudWatch Events API, so CloudWatch Events users can access their existing default bus, rules, and events in the new EventBridge console, as well as in the CloudWatch Events console.
