Avoiding Common Virtualization Mistakes

Avoiding Common Virtualization Mistakes

November 6

Virtualization is the new buzz word for expanding businesses. However, if you aren’t familiar with virtualization and its optimization, you can do your network performance more harm than good.

Virtualized Machine Optimization

Virtualized machines run on one physical machine. Each virtualized environment needs different, scaled resources. A plan should be made that identifies each virtual machine and its resource requirements. As the virtual environments are created, scale the hardware resources for each machine. For instance, an application server might need fewer resources than a database server.

Retire Virtualized Machines that are No Longer Used

It’s easy to forget about a virtual machine that’s no longer used. Corporations spend hundreds of dollars to support machines that are no longer used. To preserve costs, retire virtual machines that are no longer used. This frees up hardware resources for newer machines or other environments on the server.

Recognize Systems that are Better Suited for Virtualization

Before you decide to virtualize everything, make sure the systems you want to move to a virtual environment are best suited for that environment. Conversely, some IT managers avoid moving certain systems to a virtualized environment for fear that the systems won’t fully support virtualization. However, Linux and Windows systems are fully functional on a virtualized machine, and these systems can be even more powerful on a virtualized machine.

Licensing Agreements

Most IT shops have some sort of autonomy when it comes to building new virtualized environments. However, what these shops forget is licensing agreements for operating systems and other software. Make sure your organization has full licensing for every environment built to avoid licensing fees. This means that a license for software such as an operating system must be purchased for each virtualized machine.

Software Development Must Support Virtualized Environments

Software developers are used to a physical machine for development and staging environments. This means that software is written to support whole physical machines instead of implementing steps to support a virtualized environment and saving resources. It helps to make developers understand that their environment has been provisioned on a virtualized machine. In some cases, it might be better to train software developers who are unfamiliar with virtualized machines.

Understand Virtualized Limits

Not all systems are best in a virtualized environment. For instance, big data queries and reports don’t work well on a virtualized machine. Make sure you keep servers that need all physical resources on a separate environment.

While these are some of the biggest issues when moving to a virtualized environment, there are more issues that can hurt an organization. The best way to avoid pitfalls is to plan out provisioning and understand the limitations and scaling necessary for a secure virtualized network.
