Re: [RFC] OpenStack API



I just read the EasyAPI BP and, from a technical perspective, seems rational and sound. The challenge, of course, are the implications for the business side of the house. I realize it doesn't make sense to strive for backward compatibility to EC2/RS API's from EasyAPI, but perhaps the BP should discuss what an API Bridge might look like so we can pull out the existing API services and map them to EasyAPI?

Another point of consideration might be unimplemented features at the hypervisor level being reflected in the public API. For example, we have already added several features on the XenServer side that don't currently have sister operations on the KVM side. Should these operations appear in the public API? Or, should the choice of hypervisor cause the public API WADL to change? Perhaps it's fine to simply tell a "stack" user "<Blah> feature is not implemented for <Foo> hypervisor"?

Just some thoughts.

Hey ksankar,

We already have a blueprint to cover the Openstack API efforts for teh
Bexar release at:


See previous threads in that list: The Openstack API (1.0) support
already exists in the code, it is currently the Rackspace Cloud API.
Version 1.1 of that API (in Cactus) should have an Openstack namespace
and extensibility.

As part of the above spec, Sandy Walsh has a new python-cloudservers
library (and accompanying cloudservers CLI tool) that, with adequate
rebranding, should just be what you're looking for.
