Amazon Elastic Compute Cloud (Amazon EC2) is a web service that enables you to launch and manage Linux/UNIX and Windows server instances in Amazon's data centers. With Amazon EC2, you can get access to infrastructure resources using APIs or web tools and utilities.

Amazon EC2 provides the ability to place instances in multiple locations. Amazon EC2 locations are composed of Availability Zones and Regions. Regions are dispersed and located in separate geographic areas (US, EU, etc.). Each Region is completely independent.

By launching instances in separate Regions, you can design your application to be closer to specific customers or to meet legal or other requirements.

If a region is unavailable, then users to that region will not be able to access the server instances launched in that region. This may, in turn, adversely impact the user experience with the cloud. To avoid such an unpleasant outcome, it is best to periodically monitor the availability of each region, so that unavailable regions can be quickly and accurately identified, and the reasons for their non-availability remedied.

This test performs periodic availability checks on the monitored region, and reports the status of that region. In addition, the test also indicates the time taken for connecting to the region so that, connectivity issues can be isolated.
