To further eliminate server license management in highly virtualized environments, Microsoft introduced a data center version of its server software that provides unlimited virtualized servers in a given environment. VMware relies on the physical processors within the hardware to define licensing criteria, making server license management align with infrastructure inventory. As processor manufacturers such as Intel and AMD have released new processor technologies that combine multiple independent central processing units, commonly referred to as “cores,” on a single silicon chip, machine performance has significantly increased, which in turn allows for more virtual machines to be hosted on a single physical machine. Similarly, VMware has structured its licensing policies to reflect this shift and now defines its licensing policies through cores instead of the processor itself. “Although Microsoft treats virtualization one way and VMware treats their product another way, at the end of the day, they’re all keeping track of licenses the same way they do in the physical realm,” adds Lauria.
