Amazon EC2 provides two APIs: SOAP and Query, which allow you to launch
and control instances from your own applications.
This section discusses the operations available in the Amazon EC2 APIs,
their semantics, and their required parameters. Examples of requests
and responses are also provided.
Note
The same XML body is returned in both the Query API and SOAP API.
Before using the API, we recommend that you familiarize
yourself with their conventions.
