BS2000 (officially renamed BS2000/OSD in 1992) is the mainframe operating system platform of Fujitsu Siemens Computers.

Mainframe systems are optimized to enable many programs to be installed in parallel and run concurrently on a computer. This helps reduce the number of computers required to a minimum. Originally this was a way to achieve cost savings, since at that time hardware components were considerably more expensive than now. Today, the advantage of an architecture that gets by with significantly fewer computers is that it greatly reduces the complexity of the IT infrastructure, thus saving on IT running costs and increasing IT robustness.
