Do Plan Your Virtualization Based on the Facts

Before you start your virtualization project, evaluate your various applications' resource usage. Virtualizing systems without knowing their standard CPU/memory load, disk usage and network usage can lead to poor network performance and wasted resources. You want to ensure that there are not too many virtual machines running on a single host, resulting in poor performance, or too few virtual machines running on a host, which could result in wasted resources spent on unnecessary host servers.

With increasing pressures on today's IT professionals to minimize resources while maintaining a high-performing infrastructure, virtualization has become a go-to option for a low-cost, power-saving solutions. In fact, CIO Insight recently reported that 70 percent of senior executives said virtualization had a significant impact on efficiency and cost savings for their organization. However, deciding what within your network infrastructure to virtualize, and how to actually do it, can be a challenge.

The freedom provided by virtualization is undeniable, but even in an environment less constricted by hardware, it is still critical to keep an eye on resources. The cost benefits of virtualization are neutralized if loads aren't correctly balanced across virtual machines and if applications are not optimized to run on them. Additionally, virtualization is not a catch-all. There are many different types of application workloads that are not a good fit for virtualization and should remain on dedicated servers.

In this slideshow, Amanda Karkula, Paessler, has identified five dos and don'ts to consider when virtualizing your systems.
