Real Checkpoints - not VM Images
Checkpoints, as they are in Hyper-V and NOT VM Images as announced at Teched and already in production.
VM Images are not really the solution:
1. Amazon stores only the bits that have changed since the last snapshot, not again the whole machine.
If a have a server with TBs of data and checkpoint the virtual machine, why should I have to pay for the storage twice?
2. For a quick restore of the checkpoint, we would have to deploy the VM Image - no real solution in relation to how normal Hyper-V checkpoints work.
We will look at this as a direct Azure compute option. In the meantime, this may help: http://msdn.microsoft.com/en-us/library/azure/hh488361.aspx
