Open VMS is the most well-thought-out, stable, and secure computer operating system in the world. Many people have criticized it merely because it is a proprietary operating system. However, despite all of it's criticism, it still holds it's own in the "High Performance", "Fault Tolerant" and "Secure Systems" Computing markets today.Many financial and medical institutions today use Open VMS as their primary OS of choice because of it's stability, fault tolerance, and security. Military contractors also accept it as the quintessential OS for providing maximum security with maximum numerical throughput.
Even though UNIX has become a more prevalent OS on the Internet, Open VMS has held it's own by perfecting OS clustering for better client/server reliability. Still today no other operating system has a released version that supports multiple system clustering. Not even UNIX or Windows NT. Open VMS has been supporting system clustering for over ten years.
The next step beyond VMS Clusters are VMS Galaxies. A VMS Galaxy is a single machine either in a Cluster or not, that actually runs multiple Operating systems simultaneously. A VMS Galaxy can run multiple instances of hardware context, where each context can be (besides Good Ole' Open VMS) UNIX, and Windows NT. Certainly in the future because the instances are hardware instances in context, that other OSs, like LINUX may also be hosted.
I have been involved in the support and management of our Universities VMS Cluster for several years. I have also been VMS Consultant to some companies and other universities.
One of the best starting pages for more information on VMS is Arne Vajhj's VMS page.
