Awesome work, Suriya! Sorry I couldn't join the live Hangout but I watched the demo and it's really nice to see Stratos running on GCE. I would like to share few things :)
Does current implementation support GCE instance type given in cartridge json? I didn't see the instanceType section in your demo video. (please ignore if I missed that). If not, you could create a support JIRA for that as well. GCE also has the concept of regions and availability zones. So I think we can easily integrate Stratos partitions and network partitions model with that of GCE. Any limitations from Jclouds API that prohibits us from doing this? Again, very nice work...thank you for all your hard work.
