AWS serverless event bus service for connecting applications using events. Like a central message router that delivers events to the right destinations.
When a customer places an order, EventBridge routes the event to inventory, shipping, and billing systems automatically.
All are managed event routing services that match events against rules and deliver them to targets (functions, queues, workflows, HTTP endpoints). AWS EventBridge also supports SaaS partner event sources and a schema registry; Azure Event Grid and GCP Eventarc provide similar eventing patterns with their native integrations.
