Explanation:
CloudWatch is used to monitor AWS as well as the custom services. It provides either basic or
detailed
monitoring for the supported AWS products. In basic monitoring, a service sends data points to
CloudWatch every five minutes, while in detailed monitoring a service sends data points to
CloudWatch every minute. Services, such as RDS, ELB, OpsWorks, and Route 53 can provide the
monitoring data every minute without charging the user.
