Microsoft slapped Azure Stack with a Hyper Converged Infrastructure (HCI) moniker today to tempt those not ready to go full cloud.

Accepting that some customers might not be quite ready for the on-premises cloudy world of Azure Stack, Microsoft has unveiled Azure Stack HCI. The new product is aimed squarely at users who want something familiar in the form of virtualised applications replete with the same Hyper-V based software-defined compute, storage, and networking technologies as Azure Stack.
