Amazon CloudWatch Event Event Based Icon

Amazon CloudWatch Events, also known as EventBridge, is a serverless event bus that makes it easy to build event-driven applications. It lets you react to state changes in other AWS services or your own applications by creating rules that trigger actions based on those events. For example, you can automatically start an EC2 instance when a new object is uploaded to S3, or send an email when a specific metric crosses a threshold. Essentially, it simplifies the process of connecting different parts of your system and automating responses to significant happenings.
