Chapter 2: CloudWatch Events and Alarms

We spent the whole of the previous chapter talking a lot about the fundamental principles of monitoring. We also spent time talking about the components that make up monitoring. There are other components of monitoring systems and ways of understanding system behaviors that were not discussed. These components will be discussed as we progress, and practical demonstrations will be done. We will be exploring these components and the principles that guide how they are applied. The goal is to explain as much as possible how day-to-day scenarios connect with the Amazon CloudWatch services and architecture in ensuring high availability and better system performance.

CloudWatch has various components that make up the service. Two of the major components are the events that are converting every metric into an actionable item and the alarms configured based on a specific metric or threshold. Alarms send notifications when that threshold is met and...
