Amazon EventBridge

Amazon EventBridge is a serverless event bus that connects applications using events. While SNS provides pub/sub messaging and SQS provides point-to-point queuing, EventBridge adds intelligent event routing with content-based rules, schema discovery, and native integration with over 200 AWS services and third-party SaaS applications.
