Pros and Cons of Virtualization

Virtualization has been the focus of much data center and enterprise technology over the past few years. In fact, the majority of enterprises are now implementing some form of virtualization or cloud computing now. Even small businesses, especially those that have a significant need to process data, are finding the benefits that can come from virtualization.

Yet, virtualization isn’t all sunny days and lemonade. There are some specific challenges that virtualization poses to businesses. Understanding exactly what virtualization can do for your organization is the first step in understanding whether these pros and cons apply to your organization.

Here are some of the most common benefits of virtualization offered up by both organizations as well as vendors:

  • Lower overall capital expenditures. Virtualization means that you don’t need to purchase a server for every single application that you want to implement in your organization. By hosting multiple virtual servers on a single physical machine, you dramatically reduce your cost overhead.
  • Automated tasks. Virtualization lets you automate a number of significant routine IT tasks. Something as simple as Operating System patches become much simpler and quicker.
  • Greater redundancy. Virtualization should improve your uptime. Virtualization technologies allow greater safety and security while reducing the points of contact.
  • Faster deployment. In an virtualized environment, provisioning becomes quick and simple. Deploying a virtual machine is overwhelmingly simpler than deploying a physical machine.

There can be some downsides to virtualization, as well:

  • High upfront expenditures. When you’re implementing a virtualization strategy from the ground up, chances are you’re going to have to sink more money into hardware in the immediate future. While you’ll save in the long run, implementation can get pricey.
  • Not all applications are ready for virtualization. There are still vendors not fully supporting virtualized environments.
  • The danger of server sprawl. Because servers are so easy to deploy in a virtualized environment, there’s always the danger that new servers will be added even when they’re not needed. Instead of the 10 or 20 virtual servers you really need, you might have 30 or 40.

Virtualization is, on balance, a boon to organizations that can implement it well and that are aware of the potential downsides.
