Feature Specifications

Feature Objective

  • EC2 Query API support:
    Currently in AWSAPI, Query API implementation is not well tested. Aim is to fix Query API to have the exact fidelity as the current SOAP implementation.
  • Support for AWS Java SDK and AWS PHP SDK:
    Both AWS Java SDK and AWS PHP SDK need to be supported by AWSAPI Rest interface.
  • Support for the latest EC2 API version:
    The present SOAP implementation is against EC2 API version 2010-11-15. Goal is to upgrade the supported version from 2010-11-15 to the latest EC2 API version i.e. 2012-08-15.

API Changes

  • API's that will be supported by the Query interface are the ones that are at present supported by the SOAP interface in AWSAPI. 
  • Support will NOT be provided for any new EC2 API’s (API’s present in the latest version that were added after 2010-11-15).

After investigation of all the supported API's, the functionality of the following was found to be broken and hence will be fixed as part of this feature,
