Virtualization is the practice of hosting several “virtual” servers on a few pieces of physical hardware. Along with cloud computing, virtualization is one of the most in-demand technologies in the IT field. Companies can lower their technology budgets and increase efficiency and IT flexibility through virtualization, and are doing so in growing numbers with technologies that Dell virtualization offers. There are many benefits to be realized through virtualization.
Switch and Save – Established IT departments can save real money by converting physical servers to virtual guests as renewal periods arrive. Virtual servers require less storage space and cost much less for power and cooling. A company could host, for example, 30 virtual servers across three redundant virtual hosts, cutting the number of physical servers to power, cool, and maintain by 27.
Start Virtual – Companies just starting out might find buying enough servers cost prohibitive. These smaller organizations can save money, add IT flexibility, and get the servers they need though virtualization. As an example, consider a startup company that needs five servers to get going. The cost of those five servers might be $2000 each or more. That’s a $10,000 expenditure that a new business might not be able to cover. Buying one virtual server with extra storage and hardware capability might cost $3000. That’s a $7000 savings. When just starting out, every dollar counts.
Waive Maintenance Costs – Servers cost much more than just a one time fee. The money spent on cooling physical servers, paying for data center space, and maintaining server hardware far exceeds the amount it cost to buy them. Virtualization cuts these costs dramatically. Consider the size of a data center that houses 100 servers and what rent on that space looks like. Now think about what it costs to keep these 100 servers cool and powered, and the amount spent over time to keep them functioning with regular maintenance and repair operations. Now, consider the fact that these 100 servers could be hosted on just a handful of virtual hosts. Power, cooling, space, and maintenance costs would drop dramatically.
Ease of Use – The cost benefits of virtualization definitely make management happy, but IT departments benefit, too. Virtual machines can be created with a simple “physical-to-virtual” conversion that takes less than an hour. Templates can be created so new machines can be rolled out quickly. Snapshots of existing machines can be taken for quick backup and recovery operations. Cloud computing services can even be used to supplement the virtual infrastructure, alleviating even more burden from busy IT teams. It’s easy to see how virtualization offers unparalleled ease of use, flexibility, and savings to businesses of all sizes.
