Just how big will it get, however? According to the IDC, they predict that virtualization will command a massive $11.7 Billion market within the next four years. That's an awfully short time for such a big piece.
The press release details their analysis and why they are predicting this, with a lot of weight being put into the virtualization of x86 and x86-64 servers. They also claim that the evolving market is rapidly changing their mind regarding virtualized services, and seeing the benefits they could provide.
While $11.7 Billion is no small figure, it doesn't surprise me at all. All sorts of modern problems, such as space premiums at datacenters, power-hungry machines needing consolidation, redundancy and a host of others, all have virtualization as a potential solution. It isn't a magic wand, but with every major player leaning that direction it can only get big.
