During this session we will go into how each of the parts of Openstack correlate to the infrastructure pieces in your vSphere environment, and how you can make use of your current vSphere environment with Openstack. We will also deal with the limitations and caveats that need to be addressed with the current Grizzly version and its vSphere integration.TRANSCRIPT
