We defined the meaning of CloudWatch Events and talked about the components that make up a CloudWatch event. We further explained the importance of CloudWatch Events and gave real-life scenarios. We created an example of an automated start and stop of an EC2 instance based on a specific time of day. This was done using the scheduled expression feature in Amazon CloudWatch Events. We explained CloudWatch alarms and why it is important to integrate an alarm system into your monitoring infrastructure. Then, we implemented a basic alarm solution that sends an email when the estimated AWS bill gets to a specific amount for that particular month.

These scenarios used for CloudWatch Events and CloudWatch alarms are the criteria for understanding the basics. In subsequent chapters, the alarms will be tied to more specific and...
