I attended NYLUG event today and with 3 speakers for CloudStack, Eucalyptus and OpenStack.
I tried to be unbias and give a second chance to EU and OS (i thought maybe i missed something and perhaps EU and OS would be a better fit in my environment). I can honestly state based on Joe's presentation - CloudStack was a clear winner in terms of ease of implementation, hypervisor support and features in general. For 30 minute crammed presentation, Joe did an awesome job.
