Remember the hypervisor footprint debate? You know, the one where Microsoft Virtualization declares that it is nothing but VMware FUD to tout the benefits of a small-footprint hypervisor.
I just found another point of view on hypervisor footprint size — take a look at this excerpt:
Small footprint: any features not applicable to our specific … scenarios are removed. This guarantees that we do not have to worry about updating or fixing unnecessary code, meaning less churning or required reboots for the host. All critical code paths are also highly optimized for our … scenarios.
Any guesses where that came from? Must be more of that VMware FUD!
Actually, it was one of the Windows Azure design principles. Which makes sense if you think about it — vSphere, with small-footprint ESXi, is the perfect foundation for cloud computing.
