What is virtualization?
Virtualization is an application of technology that is fundamentally changing the way people compute by allowing one computer do the job of multiple computers. In a virtual environment, it is possible for one computer to run multiple operating systems and various applications at the same time increasing the usability and flexibility of that single computer. This frees people and their hardware from physical and geographical limitations and provides opportunity for greater efficiency and financial savings. As a result, CIO’s and CTO’s across the globe are making virtualization part of their IT infrastructure.
What types of virtualization are there?
Virtualization can take place over many platforms including application infrastructure, client/desktop applications, server virtualization and storage and network virtualization. This brief focuses on server virtualization only.
Today, many businesses are exploring a virtual model in an overall effort to go “green.” However, virtualization provides additional benefits including disaster recovery and business continuity solutions by reducing the infrastructure footprint and minimizing operational costs while striving to improve performance and reliability.
How does virtualization work?
Simply put, server virtualization allows you to take a single piece of hardware and transform it into multiple “virtual” machines. To create a virtual environment, there are many solutions available with the most popular being VMware, Microsoft and Xen. For example, VMware ESX will allow you to “virtualize” CPU, hard disk, RAM, and a network controller allowing you to run multiple OS instances on a single hardware device.
What are the advantages of a virtual environment?
Are there any downsides to virtualization?
The drawbacks in a virtual environment occur when systems aren’t managed to the level that you might maintain your physical environment. The drawbacks may be easily addressed with standards that keep systems and applications protected and running at peak performance. Following are issues to keep in mind.
If a virtual model is implemented and maintained correctly, you and your enterprise will realize a host of benefits including enhanced efficiency, expanded access to a wide range of applications and bottom-line improvement. A solid three-year strategy that is in line with your company’s objectives can easily meet growth requirements, improve time to market, significantly reduce risk, and significantly reduce overall costs.
