Alan just coined WholeSale HA. The idea of rebooting a whole virtual machine rather than just failing over 1 service.
He wants to have the best of both worlds in 1 framework, he however doesn't specify what parts he likes from the WholeSale HA setup
Yes you want to use it coupled with hardware predictive failure analysis tools. In order to achieve Higher Availabilty, but I don't think the WholeSale HA part is real HA.
WholeSale HA isn't going to be fast enough for most of the business critical environments.
You simply cannot afford to reboot or even boot a full machine and the related downtime that brings for your service.
So yes a best effort combination, but with a strong focus on the application state would be preferred. WholeSale is a good start .. but it's definitely not where you want to stop.
