Virtualization is a hot topic in the technology world. The technology enables a single computer to run multiple operating systems simultaneously. It lets companies use a single server for multiple tasks that would normally have to run on multiple servers, each running a different OS. Now, vendors are releasing products based on two lightweight virtualization approaches that also let a single operating system run several instances of the same OS or different OSs. However, today's new virtualization approaches do not try to emulate an entire hardware environment, as traditional virtualization does. They thus require fewer CPU and memory resources, which is why the technology is called "lightweight" virtualization. However, lightweight virtualization still faces several barriers to widespread adoption.
