"Moving complex legacy apps to the cloud is gaining momentum in the enterprise. appzero’s zapp migration is the right tool at the right time to speed movement to the cloud."
How is AppZero “OS-free application deployment”? Doesn’t the application require an OS?
We separate the application from the OS, packaging it into a single VAA/file for distribution – making it easy to copy and run at the destination machine. However, when the VAA arrives at the destination server (physical or virtual) the application will require a working OS in order to run. However, because the app can move among differently configured OSs in different environments, it can also easily move between Amazon and Rackspace without change.
