IncludeOS is a minimal, open source, unikernel operating system for cloud services and IoT.^[1] IncludeOS allows users to run C++ applications in the cloud without any operating system. IncludeOS adds operating system functionality to an application allowing oneself to create a 'virtual machine' for an application.

IncludeOS applications boot in tens of milliseconds and require only a few megabytes of disk and memory.^[2]

Architecture

The minimalist architecture of IncludeOS means that it does not have any virtual memory space. In turn, therefore, there is no concept of system calls nor user space.
