Definition

Amazon EventBridge is a serverless event bus service that allows applications to communicate using events. It enables the integration of AWS services, third-party SaaS applications, and custom applications by routing events from sources to targets. EventBridge simplifies event-driven architectures by providing a centralized hub for event ingestion and processing, supporting both predefined and custom event patterns.
