Hyper-V: Free or Licensed the Choice is Yours

Which is better Hyper-V version deploy for production environments? For a traditional server based virtualization project, it makes financial sense to deploy Datacenter, and this is most likely the case for a hybrid deployment of Server and Desktop devices. However, for raw VDI and Open source deployments, it is obviously more fiscally prudent to utilise the free version which has been available for over a year.

Virtual Disk Encryption
