Recently an former VMware colleague of mine sent me an email. His new employer’s IT department encountered a variety of problems with the virtualized deployment of their custom application. Now they are reluctant to put business-critical applications on vSphere. The tide of virtualization is crushing them from all sides so they know that they need to figure out what has gone wrong and produce a functional virtual environment. But where to start? And how can they mitigate risk and avoid any more failures?
At my friend’s request I spent some time thinking about this. I sent him a long response and thought I would share it with you.
