Amazon CloudWatch

Imagine we have a large, complex machine in our factory that performs many tasks. To ensure it runs smoothly and efficiently, we hire a diligent supervisor who constantly monitors the machine's performance. The supervisor keeps track of things like the machine's speed, temperature, power usage, and any errors that might occur. If something goes wrong or needs attention, the supervisor alerts us and provides us with relevant information, so we can make informed decisions about how to address the issue.

In this analogy, Amazon CloudWatch is like the diligent supervisor, and our AWS resources (such as Lambda functions or other services) are the complex machine. CloudWatch continuously monitors our AWS resources, gathering data on various performance metrics and operational health. This data is then made available to us in the form of detailed graphs, dashboards, and reports, giving us a comprehensive view of our resources' performance and health.
