Unfortunately, virtualization will not…
- instantly cool your data center
- instantly reduce operating expense
- instantly reduce server counts
- instantly increase availability
The sad reality is, implementing virtualization is a project (and there’s usually already a huge IT project backog), which must drag in resources from almost every functional area (e.g., server administration, DBAs, networking: all of who are working on other projects), will probably require more servers and storage, which increases heat and power consumption. (And decommissioning those servers is yet another project.)
And because virtualization changes how changes are made, it requires changing SOPs and processes. Until those are mastered, virtualization will probably increase the number of accidents and outages, generating more unplanned work for everyone, and create more reactive work for security.
