If you maintain an application on AWS, you may have heard about Amazon CloudWatch already, the monitoring service of AWS. Amazon CloudWatch gathers metrics from your AWS resources such as CPU or memory usage, and your resources emit events to CloudWatch when their states change, such as an auto-scaling launch event.

You can define thresholds on your metrics and trigger alarms if those thresholds are exceeded. Besides, you can take actions on a specific event, for example, by triggering an AWS Lambda function. Hence, both features help you in monitoring the states of your resources and get notified or take proactive or reactive actions to protect the health of your workload.

As you start using AWS CloudFormation for bigger projects, your templates and stacks get larger. Therefore, managing them gets more difficult day by day. Then, at some point, you realize that you need a way to divide your templates into smaller ones to manage them more efficiently.
