Sanos 1.3.4

A minimalistic 32-bit x86 OS kernel for network server appliances
  1 Screenshot
Sanos is a minimalistic 32-bit x86 OS kernel for Java based server appliances running on standard PC hardware.

This enables you to run java server applications without the need to install a traditional host operating system like Windows or Linux. Only a standard Java HotSpot VM and the sanos kernel are needed.

The kernel was developed as part of an experiment on investigating the feasibility of running java server applications without a traditional operating system only using a simple kernel.

The kernel implements basic operating system services like booting, memory management, thread scheduling, local and remote file systems, TCP/IP networking and DLL loading and linking.

A win32 layer allows the Windows version of the standard HotSpot JVM to run under sanos, essentially providing a JavaOS platform for server applications. This enables you to run java based server applications, like tomcat and jboss, under sanos.

Alternatively, you can use sanos as a small kernel for embedded server applications written in C. Sanos has a fairly standard POSIX based API and an ANSI Standard C library. In this case you don't need the JVM and the win32 wrappers.

Sanos is open source under a BSD style license. Please see the COPYING file for details.

Sanos can be downloaded as either binary or source. All the files in the binary version can be built from the source version, so you do not need the binary version, if you are building sanos from source.

The binary version contains the compiled version of sanos, with files and utilities for making a boot disk.

The source version contains all the source code and build files for building sanos from source. You will need a Microsoft Visual C compiler to build sanos from source.
