Of course you do. We all do. But that sometimes comes at a cost. And by cost, I mean actual money. Dollars and cents. Do-rey-mi. $$$
But Microsoft gives you the ability to patch your virtualization foundation for FREE. (That’s another big zero, folks.) So, even in a Windows Failover cluster of 64 virtualization host-nodes running up to 8000 virtual machines, you easily launch a Cluster-Aware Update.
“Wow.. And am I right in assuming that this update will automatically move VMs around so that there is no downtime?”
Right you are.
“And how does that work?”
So to summarize; using Hyper-V for virtualization results in this:
Zero downtime + Zero additional Cost = PRICELESS
