Some will describe server virtualization as a big game-changer and revolutionary. However, it is not new or a trend. Nevertheless, businesses and organizations of all sizes can benefit from virtualization technology, providing them with efficiency when they need it. Regrettably, very few companies are taking advantage of being virtualized.
Essentially, server virtualization masks server resources, like the number of physical servers, their identity, operating systems and processors, from users. This can occur when an administrator makes use of software that divides a physical server into multiple virtual environments. Sometimes, these virtual environments are called virtual private servers, but may be named instances, emulations, or other terms. Regardless, server virtualization can lead to many positive benefits.
1. Server Virtualization Can Reduce Hardware Costs
Have you ever heard the idea that humans only use roughly 10 percent of their brain’s capacity? Similarly, in a strictly physical environment, a server will typically use only an estimated 5 to 15 percent of its capacity. Virtualization will turn one physical machine into multiple virtual machines. And, this consolidation can result in a 40 percent cut in hardware and software costs.
2. Rapid Server Provisioning and Deployment
Virtualization can also cut the cost and time involved in installing a new server. Within minutes, an administrator can clone a virtual machine and have a new server up and running. In contrast, a new physical server will need to be purchased, delivered, and the operating system and software installed. Moreover, there is the additional cost more cables, racks, and other hardware needed to accommodate added physical servers.
3. Major Reduction of Energy Consumption
Server consolidation can reduce cooling and energy costs by as much as 80 percent. Is that something of interest to you? Many companies and organizations are looking for ways to “go green”. However, many energy saving initiatives have a significant upfront cost. Yet, server virtualization is one “going green” strategy that starts with upfront savings.
