For the last 3+ years our company has been using VMs. But mostly for for Web and APP servers. Now with the latest hardware and memory prices, we are diving into VMimg our production SQL and Oracle servers. Now we are going from a throw it in VMWare and it works to a plan it, develop it, deploy it, test it shop. We are having to spend a lot of time on resource allocation and even more on making sure our code runs well. Before VMs sloppy code could exist because the servers could handle it. Now sloppy code on shared infrastructure can degrade several system not just the sloppy one.

I think as VM or Cloud computer expands, DBAs, system admins and developers are going to be working even tighter to get their systems lean and mean. If you are paying for clock cycles on someone else's SQL or Oracle server infrastructure, you don't want to waist your money on poor code. And as you grow your own VM farms, you will find that managing code is just as important.
