"How often is your hardware fucked up enough that you need to move to another machine?" VMware HA runs quite a bit IME for a variety of reasons (network failure, storage issues, etc). "The network is reliable" is a classic fallacy of distributed computing. More often used is Vmotion and DRS which transparently moves VMs around physical hosts at runtime with no downtime and very minimal performance hit . Servers, switches, and fabrics need maintenance, firmware upgrades, hypervisor OS patches, etc. in most data centers. "That would be great, right? You paid some $ to VMWare and now your servers never go down? Excuse me but, that did not happen." VMware FT is used in almost every major company on the planet that runs virtualized database instances that can't go down. It is serious technology. AWS has mopped up the IT industry to date, and this is them going hard after Microsoft which is making inroads.
