Processor.com published a short but very useful interview with Raghu Raghuram, Vice President for Products and Solutions Marketing at VMware, about common errors of virtualization newcomers:
- Not setting up a good system to track testing before deployment
- Not building enough redundancy into the hardware powering your virtual machines
- Not changing your process workflows to account for virtualization
- Failing to account for virtualization in disaster recovery preparation
Unfortunately such errors happen more frequently in small businesses where, even wanting, budget constrains limit capability to follow some of these precious advices.
So a last warning emerges: virtualization saves big money but the path towards it is not cheap. Even with free virtualization products.
