Along with image and object storage these make the whole of OpenStack today. The goal is to see where we are at wrt the OpenStack API (compute/network/volume/image) and coverage of the underlying implementation as well as what is available through the EC2 API today.<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>I would propose that volume and network API’s be exposed not through the core compute API, but as extensions. Once we create separate services and factor network and volume services out of nova these API’s will form the core API’s for these services. We may also need to up-version these service API’s between Cactus and Diablo as they are currently under heavy discussion and design.<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>John<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Erik Carlin [mailto:erik.carlin@rackspace.com] <br><b>Sent:</b> Monday, February 28, 2011 3:16 PM<br><b>To:</b> John Purrier; openstack@lists.launchpad.net<br><b>Subject:</b> Re: [Openstack] OpenStack Compute API for Cactus (critical!)<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal><span style='font-size:10.5pt;color:black'>John -<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;color:black'>Are we just talking about compute aspects? IMO, we should NOT be exposing block functionality in the OS compute API. In Diablo, we will break out block into a separate service with it's own OS block API.
