The two biggest players on the x86 server virtualization market recently entered the public cloud Infrastructure as a Service (IaaS) market as well.
Microsoft Windows Azure Virtual Machines went general available in April 2013. VMware vCloud Hybrid Service went general available in August 2013. Some believe the rivals for server virtualization will become rivals as well in the public and hybrid cloud space.
This post will describe why both cannot be compared.
Both Azure and VCHS provide customers the ability to create cloud based virtual machines and have control over the guest operating system and applications running on top of it. That is basically the IaaS model.
