Virtualization technology allows developers to create multiple virtual testing and development environments on a single physical machine. The cost-saving implications are just the beginning of the story.

n a world of multiple operating systems, each with various versions, no developer has the luxury of building applications for only one target configuration. Every developer needs to ensure that his or her applications will function correctly on all the OS configurations used by today's heterogeneous IT environments. Because dedicating physical test systems for each target environment is out of most development teams' budgets, virtual machines (VMs) are the right solution at the right time.
Virtualization solutions enable you to run multiple VMs on one physical computer. Each VM behaves as an isolated physical PC or server with its own configuration—a very useful testing and development environment that's much cheaper than the real thing. Java developers know the benefits of the VM concept well. The promise of enabling developers to "write once, run anywhere" was a key factor in the broad adoption of Java, which itself runs on the Java Virtual Machine.
