Monitor, Alert, and Auto scale
Windows Azure provides a number of capabilities that help you to better understand the health of your applications. You can now monitor the health and availability of your applications, receive notifications when your service availability is degraded, perform actions based on events of interest, and automatically scale to match the current demands. Availability monitoring, auto scaling, and alerting are available in preview for Windows Azure Web Sites, Cloud Services, and Virtual Machines. Availability monitoring and alerting are available in preview for Windows Azure Mobile Services. There is no additional cost for these features while in preview.
