Virtualization: Top 10 Virtualization Best Practices

Virtualization has gone from being a test lab technology to a mainstream component in datacenters and virtual desktop infrastructures. Along the way, virtualization has occasionally received a “get out of jail free” card, and has not had the same degree of efficient IT practices applied to virtual deployments as would be expected of actual physical machines. This is a mistake.

If you had an unlimited budget, would you let everyone in your organization order a new system or two and hook it up to the network? Probably not. When virtualization first appeared on the scene, unlimited and unmanaged proliferation was kept in check by the fact that there was actually a cost associated with hypervisor applications. This provided some line of defense against rogue virtual machines in your infrastructure. That is no longer the case.

There are several free hypervisor technologies available, for both Type 1 and Type 2 hypervisors. Anyone in your organization with Windows installation media and a little free time can put up a new system on your network. When virtual machines are deployed without the right team members knowing about it, that means a new system can become an unwelcome honeypot for new zero-day vulnerabilities, ready to take down other systems on your network that are business critical.

Virtual systems should never be underappreciated or taken for granted. Virtual infrastructures need to have the same best practices applied as actual physical systems. Here, we will discuss 10 key best practices that should always be on your mind when working with virtual systems.
