Standardizing your virtual machines with templates saves time, effort, and money in both deployment and management.

Virtualization aims to maximize savings through consolidation and standardization. Although the largest savings come from consolidating many virtual machines (VMs) onto fewer physical servers, standardizing your installations can save significant costs in provisioning and managing virtual machines.

Maximizing virtualization benefits means getting the best match of virtualized and physical resources.

In theory, you can put any virtualized workload on any server. In practice, it’s more complicated than that. First, you want to use as few servers as possible to support virtualized applications and servers. (That’s one place you get cost savings, after all.) Second, you want to avoid single points of failure and improve overall efficiency. It takes a fair amount of planning to do server virtualization right. READ MORE

Server virtualization saves money and power, but that doesn’t mean you should virtualize everything. Some resources should be left alone.

“Because we can” is a lousy reason to virtualize a server.

Yet in a surprising number of cases that’s what the argument for virtualizing a particular server boils down to. The company has a virtualization initiative under way and that server is just sitting there, so . . .

While the advantages of server virtualization are undeniable, that doesn’t mean it’s a good idea to virtualize every application and every server in the data center. In fact, in some cases, using virtualization is asking for trouble. A “virtualize everything” policy can cause many problems, including degraded performance, support headaches, increased licensing fees, and sudden lack of support from software vendors.
