Microsoft's Cloud Computing Patent Application

Windows Azure at Cloud Expo

Today, Alexander Wolfe has been speculating about Microsoft's patent application regarding data migration between cloud services.

Although on the face of it, a patent for Cloud migration would appear to be aimed at removing the lock-in associated with a single vendor, the patent application is in fact aimed within a single vendor system.

So, it doesn't address the Cloud lock-in problem which has been identified by ENISA as the #1 risk of cloud computing

Lock-in to a single vendor can be addressed using a Cloud Service Broker solution which mitigates against the use of a single Cloud service by brokering the connection up to the Cloud service, allowing a switch-over at the interface level to a back-up Cloud service in the event of service failure.
