it's weird
OpenStack... from day zero, looking at their web site and such, my impression is that this thing has evolved into a vehicle to pull in supply side sponsorship to allow vendors to push product and/or services. Obviously there is a lot of supply-side interest to get on the bandwagon. AFAICT it remains to be seen whether there is actual, well, demand-side demand.
This theory can be proven wrong. Does anybody have numbers on, for example, how many VMs run under control of an OpenStack environment, vs competitors (VMware, Amazon, Microsoft, etc)?
