Understanding the components of a CloudWatch event

For an Amazon CloudWatch event to function, it is made up of different moving parts to achieve a goal successfully. Each of these components is inter-connected and forms the life cycle of a CloudWatch Events operation. If any of these components is missing for any reason, then the CloudWatch Events life cycle will not be complete. Due to the similarities that exist between CloudWatch Events and Amazon EventBridge, we will be interpolating both services by describing the different components of CloudWatch Events. In scenarios where the features are unique to Amazon EventBridge, they will be uniquely spelled out. For an event to work completely, these are the three major components, which we will explore in the next sections.
