Windows Server + Virtualisation = Licensing Confusion
Conclusion: In spite of changes over the last decade the Microsoft Windows Server licensing is still rooted in the physical machine era of the ’90s. However, most organisations run the majority of their x86 workloads in virtual machines. Microsoft’s disconnect with the virtualisation realities of the last five years can result in licensing confusion. Organisations that choose the wrong licensing approach will either greatly over-spend on Microsoft licences or, more likely, not be compliant.
