Microsoft's Cloud Migration Patent Application

Today in InformationWeek, Alexander Wolfe speculates 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.
