EventBridge used to be called CloudWatch Events, which helps explain why it is featured in this section.
From AWS documentation:
"Amazon EventBridge is a serverless event bus service that you can use to connect your applications with data from a variety of sources. EventBridge delivers a stream of real-time data from your applications, software as a service (SaaS) applications, and AWS services to targets such as AWS Lambda functions, HTTP invocation endpoints using API destinations, or event buses in other AWS accounts."
EventBridge receives an event, an indicator of a change in environment, and applies a rule to route the event to a target. Rules match events to targets based on either the structure of the event, called an event pattern, or on a schedule. For example, when an Amazon EC2 instance changes from pending to running, you can have a rule that sends the event to a Lambda function.
We will encounter EventBridge in a lab on day 5 when we look at Step Functions and serverless workflows.
