I didn't feel like making a complete overview of the whole landscape, since this news is about VMware workstation in specific. Therefore any VMWare product in use by server hosts would in all likelihood not be VMWare Workstation/Fusion.
Aside from your personal attack, this is besides the point, as this is about a desktop product not a server product, which is the important difference that had to be noted in response to the post I was replying to.
Please refrain from personal attacks on this forum, it's one of the last nice places on the Internet.
That, or OpenStack. I know it's a bigger deal for telcos and wraps kvm, but it's very reliable, scalable, and has all the features a hosting provider would need.
You're right that it's not a hypervisor, but it's not an AWS emulator either. It's a collection of tightly coupled management layers for other open source projects that form a new, cohesive whole that can be competitive with AWS at a medium scale.
It's the complacency trap many FOSS and non-FOSS legacy products fall into when corporate bureaucracy dominates while failing to realize their policies and practices are counterproductive.
