AWS EventBridge
AWS EventBridge is a serverless event bus service that enables real-time, event-driven communication between applications, AWS services, and third-party SaaS providers. It simplifies building event-driven architectures by routing events from sources to targets based on rules, without managing infrastructure. It supports events from AWS services, custom applications, and partner services like Datadog or Zendesk.
Developers should use AWS EventBridge when building decoupled, scalable applications that require real-time event processing, such as microservices architectures, serverless workflows, or integrating multiple AWS services. It's ideal for scenarios like automating responses to infrastructure changes, orchestrating multi-step processes with AWS Step Functions, or centralizing event logging and monitoring across hybrid environments.
