What Amazon EventBridge is
Amazon EventBridge is a cloud-based serverless event broker for applications that respond to events from software, SaaS integrations, and AWS services. It routes events across AWS accounts, with subscriptions that can filter events, select targets, and set retry policies. Event buses support tens of thousands of subscribers, retention for up to 365 days, and JSON, Avro, Protobuf, and Cloud Events formats. EventBridge also supports ordered delivery and sharing a bus across accounts in an AWS Organization through AWS Resource Access Manager. Pipes connect endpoints point to point, with optional transformation, filtering, and enrichment. Supported SaaS events can be routed to AWS service targets; listed partners include Adobe, Datadog, MongoDB, Shopify, Stripe, and Snyk. API destinations send bus or pipe events to web applications on public or private networks. Monitoring and logging use CloudWatch metrics and several listed destinations. IAM access controls, VPC endpoints, and TLS 1.2 encryption in transit are supported. The free plan has no minimum charge for event buses; classic-bus payloads are billed in 64 KB chunks, and inter-Region transfer may add charges.
