Application and system alerts

It is important to monitor AWS resources over various parameters (that is, CPUUtilization, MemoryUtilization, NetworkIn, NetworkOut, and so on) to avoid bottlenecks and to deliver consistent web application performance to the end user. As resource consumption crosses the defined threshold, the administrator should get an alert. This alert can be in the form of an SMS and/or email to the system, network, or a database administrator, based on the resource type. Other AWS services also use SNS to send notifications on certain events. For example, an autoscaling group can also optionally inform the administrator upon scale-out and scale-in using SNS notifications. Subsequent points describe mobile device push notifications, push emails, and text messaging.
