JeOS (just enough operating system)

Part of the Virtualization glossary:

What is JeOS?

Next Steps

JeOS (just enough operating system) is a highly customized operating system built for a specific application. The acronym is pronounced "juice."

JeOS builds are popular with software vendors and developers who are creating test systems or virtual appliances.  A virtual appliance is simply a virtual machine (VM) image file that has a preconfigured operating system (OS) and a single application. (The preconfigured OS is the JeOS.) 

A JeOS only includes the bits of a full-blown operating system that are required to support the application and any other third-party components that are packaged in the appliance.  Configuring the JeOS and the application together in a single package helps avoid installation issues and errors.
