   **About Amazon EventBridge**
 
 
-  {ADD YOUR DESCRIPTION HERE}
+  EventBridge is a serverless service that uses events to connect application components together, making it easier for 
+  you to build scalable event-driven applications. Use it to route events from sources such as home-grown applications, 
+  AWS services, and third- party software to consumer applications across your organization. EventBridge provides a simple
+  and consistent way to ingest, filter, transform, and deliver events so you can build new applications quickly.
