What is Server Virtualization Software?

Server virtualization software helps businesses optimize their server resources. The software divides a physical server into multiple virtual or private servers, so companies don’t have to rely on one single server to carry out a task. Typically, a data center has multiple servers which perform various functions. However, many of these servers remain inactive. Server virtualization software solves this. It lets an administrator delegate a specific task to a server, streamlining hardware resources and reducing costs.

Server Virtualization Software

Server virtualization provides cheap Web hosting services for businesses. Instead of using one server to handle Web hosting, an administrator can manage several virtual servers simultaneously. Each virtual server can have a designated processor, hard drive, RAM or network of its own. This drains fewer resources from a physical server, resulting in cost reductions for a company. Each server performs just like a physical server but reduces power and maintenance costs.

Some of the most popular server virtualization tools include Microsoft Hyper-V, Oracle VM and XenServer.

Benefits of Server Virtualization Software

Server virtualization software maximizes resources. Smaller, virtual servers are independent of one another, with each running a different operating system. This helps companies save money, as less hardware is needed to carry out a task.

This software lets companies increase their server uptime (the amount of time a server stays operational), which could result in bigger sales. When a task is allotted to a machine, a virtual server handles the workload quicker than its physical counterpart, thus reducing page waiting times for consumers. Server virtualization software could also improve disaster recovery. Companies will no longer need to maintain a physical server that could be vulnerable to a natural disaster (like a flood, for example) and can use cheaper, virtual servers instead.

In addition, when a task is assigned to a virtual server, it becomes easier for administrators to identify and solve technical problems.

What Users Say

“I have a comprehensive test automation framework, and it needed more than 20 VMs to be used as test execution nodes,” says a user who reviewed VMware vSphere, a type of server virtualization software. “We used vSphere to meet our requirement. Since the tests were running in parallel, it was important to monitor the health of the test nodes to ensure that they are not running out of resources.” Another user, an administrator for libraries, says: “When we finally got the budget approved for VMware, we made the switch. The total cost was far less than what I had originally anticipated, which was nice.”

“We were ready for a major hardware update of 16+ physical servers,” says a reviewer of Hyper-V, a server virtualization platform from Microsoft. “After looking at the cost of new hardware vs. the cost of a future-proofed cluster of beefy servers that you could run a space program on, Hyper-V ended up being very cost-comparative. Plus, we get to be all virtual now. We’re part of the cool kids club.”

Server virtualization provides companies with a wealth of cost saving benefits. Businesses can increase their uptime, improve their data recovery processes and identify technical problems quickly without having to purchase brand new hardware.
