12.1. Amazon Web Services Compatible Interface

CloudStack can translate Amazon Web Services (AWS) API calls to native CloudStack API calls so that users can continue using existing AWS-compatible tools. This translation service runs as a separate web application in the same tomcat server as the management server of CloudStack, listening on a different port. The Amazon Web Services (AWS) compatible interface provides the EC2 SOAP and Query APIs as well as the S3 REST API.

Note

This service was previously enabled by separate software called CloudBridge. It is now fully integrated with the CloudStack management server.

Warning

The compatible interface for the EC2 Query API and the S3 API are Work In Progress. The S3 compatible API offers a way to store data on the management server file system, it is not an implementation of the S3 backend.

Limitations

Supported only in zones that use basic networking.
Available in fresh installations of CloudStack. Not available through upgrade of previous versions.
Features such as Elastic IP (EIP) and Elastic Load Balancing (ELB) are only available in an infrastructure with a Citrix NetScaler device. Users accessing a Zone with a NetScaler device will need to use a NetScaler-enabled network offering (DefaultSharedNetscalerEIP and ELBNetworkOffering).
