Advantages And Disadvantages Of Using Virtualization
An estimated 85% or more companies utilize virtualization at some level, and when you might not have invested in virtualization, the level of adoption means that you need to start soon. Virtualization is the process where software works and functions like a hardware. A good example is when one runs both Windows and Linux operating systems on a given computer where the computer pretends that one of the operating systems has own hardware. Virtualization has both pros and cons, just as with most tech advances.
One of the benefits that come with virtualization is server consolidation. Companies have struggled over the time to use servers computing powers. Even though raw computing has been in existence, the software setup ran only one instance at a time, and when a company wanted to expand its capacity, it would mean spending on more servers. Virtualization makes it possible for the company to take advantage of all the raw computing power through consolidation of servers, where there are multiple operating systems on the same physical server.
Virtualization will also enhance productivity. As lean methods trickle down into the basic thinking, one of the primary concerns is productivity. One of the significant principles of lean thinking is reducing waste, and one of the areas of potential waste is employee time.
The company is also set to save cash in the long run through virtualization. The business and enterprise-grade servers are very expensive for the company, as well as the cost of software licenses. The replacement costs can also be a concern for the company since most businesses settle for a 3-year to 5-year replacement cycle. By consolidating the servers, the company avoids the high cost of purchasing the servers, and the reduced number of servers also means less maintenance cost.
One of the cons of virtualization is the short term cost to the business. When the servers in your company are on the last year of the replacement cycle, they will not work for virtualization. The company not only incurs the cost of covering virtualization, but it will also pay for the software licenses that work for the virtualization. When the company has software that doesnt work for virtualization, they might need to purchase new apps, or the company will have to run a separate server that supports the one or two applications required by the company.
The company might not have hired on virtualization skills when looking for IT experts, and the use of a virtual server might be very new to the IT staff in the company. When the company considers utilizing virtualization, you might be forced to recruit new IT experts, or the current staff might need to get up to speed on the infrastructure for the company to benefit from virtualization. For example, Citrix storefront customization can be an easy task for a trained individual, but it will be slow and error-prone if handled by someone who never heard about Citrix before.
