Virtualization Technology News and Information
Virtualization OSes & Apps
Another great article about virtualization and the different approaches taken by various vendors.  When trying to decide on a platform to perform the function you need, it is important to first identify exactly what it is you want to accomplish and then select the appropriate tool to perform that task. writes:

Computing architectures seem to go through cycles of essentially the same approaches to the same problem. Delivering applications to users reliably and at the lowest cost has always been the ultimate goal. How to accomplish that task has varied over time.

Large mainframe computers delivered a hefty amount of computing power and the ability to support hundreds of simultaneous users on “dumb” terminals. Personal computers brought the power to the user’s desktop but didn’t adequately address issues such as application distribution and data backup.

The advent of computer networks made it possible to connect PCs to a central server and provide services such as backups and management from a single location. Dedicating servers for one or two applications caused an explosion of hardware in many corporate data centers. Newer, more powerful multiprocessor machines now make it possible to consolidate those dedicated servers onto a single box when used in conjunction with virtualization software.

Server consolidation is probably the biggest use of virtualization software in the data center. Creating a standardized testing environment is another good application, making it possible to test software updates or patches on different configurations before they are rolled out to the entire organization. Software development and testing also benefit from virtualization because you can easily test a program against any number of different operating systems and configurations.

Here are a few of the more popular virtualization products available for the small to midsized enterprise.
