Amazon EventBridge relaunches event buses for enterprise scale

Amazon EventBridge relaunches with an enhanced Custom event bus designed for enterprise-scale event-driven applications that decouple teams and scale with organizations.

• Share custom event buses across accounts using AWS Resource Access Manager for centralized event routing
• Publish events in popular JSON formats like CloudEvents while preserving schema without modification
• Built-in 24-hour retention extendable up to one year for error recovery and historical data hydration
• Native support for strict event ordering and automatic content-based deduplication
• New Subscriber resource filters events and delivers to over 250 AWS services
• Available in 14 AWS Regions across US, Europe, and Asia Pacific
• New pricing model charges for data transferred rather than events, reducing costs at scale

The enhanced Custom event bus enables scalable, decoupled event-driven architectures with enterprise features while the existing bus is renamed to Custom event bus - classic.
