IT Experts Discuss Virtualization

When you hear the word virtualization, what comes to your mind? You may think that is an operating system installed in your computer to boost performance.

Virtualization is actually hardware emulation that makes it appear the operating system is running as if it were installed on your computer, but that is not really the case. The hardware emulator is regarded as a virtual computer or a virtual machine, and the operating system is installed within the virtual machine, or on a server somewhere else.

Virtualization is the solution for many of the most difficult problems in IT today. This challenge is the need for infrastructure that can channel 70 percent of an IT department's budget to cost of maintenance, leaving few resources for other business needs.

How does virtualization work?

The hardware emulated in virtualization is usually a generic PC that provides the virtual machine with its own resources such as hard disk space, RAM, CPU, video adapter and I/O devices such as keyboard, CD network,and mouse. The virtualization software runs in a host operating system that also runs on the computer.

The principles of virtualization are applied to different network resources by abstracting, automating and pooling them beyond the limitations of physical architecture. IT services are assigned to each network application and adapt to changing requirements.

What is the difficulty faced by IT services?

Today’s X86 computers are only designed for one application and operating system at a time. Because of this, small data centers have to deploy many servers. Each server may only operates at 5 percent to 15 percent capacity, which is very inefficient.

What benefits can be derived from virtualization?

Virtualization consolidates applications to fewer servers:

  • Several applications and operating systems run in one host or physical server, resulting in 80 percent higher utilization for each server.
  • Each virtual machine is independent from others, so they can maximize the use of computing resources without interference.
  • For every server virtualized, there can be an annual savings of up to $1,500, and capital and operation expenses can be reduced by 50 percent.
  • Applications can be deployed and used faster.
  • IT services can be automated with virtualization software.
  • Lost revenue is minimized due to decreased planned and unplanned downtime.
  • Better disaster recovery solutions are available for virtualized systems, improving business continuity.
  • Virtualize enterprise apps including Oracle, SAP, SharePoint and SQL Server for improved performance.
  • Run multiple applications and operating systems on a single computer to save money on hardware puchase and maintenance costs.
