CloudTest locations define geographically separated groups of servers. This could be any of the following:
- Sets of physical appliances located in different data centers
- Different Amazon EC2 regions (e.g. U.S. And E.U.)
- Different computing cloud vendors
In addition, a location can be used to represent a "simulated" computing cloud environment, for testing purposes.
When configuring a location, one of the key considerations is whether or not servers within that location can be contacted from "outside". This decision is usually made for you by your network administrator. For example, when using physical data centers, your firewall will either allow external access to individual servers, or not.
