Fixup Software Ltd. offers design and implementation consulting for minimal footprint software stacks which provide maximal performance and security.

The problem with contemporary mainstream operating systems is that their design derives from the mainframe world of 50 years ago. In the modern world of embedded systems, IoT and cloud services, the classic OS brings a plethora of baggage such as vast resource consumption, performance issues and security concerns. However, OS-like components are still required to provide the services which applications rely on: e.g. TCP/IP, device drivers and file systems.

Our speciality is the rump kernel technology, which was created in 2007 by Antti Kantee. Rump kernels provide essential operating system components, such as TCP/IP, device drivers and file systems. For example, rump kernels are the core and soul of the Rumprun unikernel, the first unikernel to support POSIX applications. The first working release of Rumprun cost less than a person-month of developer time and was created by using rump kernel components on top of custom assembly and bootstrap code. Are you aware of another way to create custom production-quality operating systems and unikernels in less than a month of developer time?
