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 deliver events from producers to consumers using rules/filters. AWS EventBridge and Azure Event Grid are general-purpose event buses/routers; GCP Eventarc focuses on routing events to services like Cloud Run and GKE; OCI Events routes events from OCI services to targets like Functions, Streaming, and Notifications.
