VMS Software, Inc., founded in 2014, is the exclusive developer of OpenVMS, an enterprise operating system used in mission-critical environments. The company develops the operating system and provides migration, modernization, support and training services for its customer base. OpenVMS has traditionally achieved 99.999% uptime over a history of more than 40 years, and is deployed across government, healthcare, financial services and enterprise computing.
Engineering work at the company centres on the operating system itself and on its portability across hardware generations. OpenVMS, originally available on VAX, Alpha and Itanium platforms, has been ported by VMS Software to modern x86-64 architecture. Alongside the core product, the company builds migration services that move mission-critical OpenVMS applications to contemporary x86-64 hardware and modernization tools for existing applications. Relevant technical domains include operating systems, legacy platform migration, x86-64 architecture porting, enterprise systems modernisation and high-availability computing.
The company positions itself as custodian and steward of the OpenVMS ecosystem, with a stated focus on protecting customers' existing application investments. Its work spans the full lifecycle of long-lived enterprise systems: development of the operating system, professional support for OpenVMS and its layered products, and training programmes for customers and users. VMS Software operates globally, with offices in the United States and Armenia.
