Had to mention this one now that vSphere 5 is available on a fault tolerant platform. Just as the virtualisation stack gets better and better, so the expectation of availability increases too.

Never thought about the concept of “IT chicken” before but how true it is. Check out hard truth number 3 in this one. And I guess that’s the game. If you don’t pay for uptime upfront then when your system goes down, it costs you more than if you had spent the money in the [...]

Some great ideas in here of “re-directing budget” by deploying simple and highly-reliable technology in certain areas of your business.
