Curtis, thank you. I still have few questions, if you don't mind… These probably the last on the subject :) thanks again. See below:

This is interesting - definitely gives you better resource use in a large environment (but also brings up some ownership issues in an enterprise environment). By putting it in large cloud, do you mean physically move/join all compute nodes to a large OpenStack cloud (with VCL tenant as one of many others) or *bursting* into a different cloud when you run out of resource on VCL OpenStack cloud? My main interest with OpenStack (or any other private cloud solution) is if it can provide resource sharing between multiple OpenStack private clouds. Let's say I had the same configuration of VCL&OpenStack, could we configure our both OpenStack private clouds to share resources if needed? I.e. - I don't have available resources to create new reservations, could those reservations be hosted in your private OpenStack cloud temporarily? without end user get involved? > > > I think the image management systems, glance, is also beneficial.

By HA I meant if there is any redundancy on KVM/VMs side of OpenStack, i.e. if one of your KVM hosts went offline would VMs restart automatically on another host? Can you move VMs between hosts on OpenStack side? > > Thanks, > Curtis. > > > > > > > On Feb 14, 2013, at 16:16 , Curtis <[email protected] > > (mailto:[email protected])> wrote: > > > > > Hi All, > > > > > > I just put up a blog post on how we are using OpenStack and Apache VCL on > > > the Canadian OpenStack Users Group (CanStack) blog here: > > > > > > http://blog.canstack.ca/2013/02/14/vcl-openstack-reference-architecture.html > > > > > > Though I didn't put in much information about the OpenStack VLC module we > > > are using, but it's at least an idea of what we have in terms of > > > hardware, networking gear, and a few OpenStack tidbits for a small > > > private cloud. > > > > > > Thanks, > > > Curtis. > > > > > > PS.
