s to fit the needs of a particular application such as for a
software appliance
A software appliance is a software application combined with just enough operating system (JeOS) to run optimally on industry-standard hardware (typically a server) or in a virtual machine. It is a software distribution or firmware that impleme ...
. The platform only includes the operating system components required to support a particular application and any other third-party components contained in the appliance (e.g., the
kernel
Kernel may refer to:
Computing
* Kernel (operating system), the central component of most operating systems
* Kernel (image processing), a matrix used for image convolution
* Compute kernel, in GPGPU programming
* Kernel method, in machine learnin ...
). This makes the appliance smaller, faster (to boot and to execute the particular application) and potentially more secure than an application running under a full general-purpose OS.
Common implementations
Typically, a JeOS will consist of the following:
* JeOS media (OS core
ernel, virtual drives, login
* OS minimum maintenance tools
* Minimum user space tools
* Packages repository (DVD or network-based)
It is important to differentiate between true fully ''minimalized OS'' install profiles forced, for example, with security hardening tools or representing Recovery Console images and ''JeOS'' richer install profiles which are designed and built for wider audience usage, so
VM/
VA creators and their users can easily perform needed installation or configuration tasks.
