OpenVMS recently celebrated its 25th anniversary, and, since first booting on VAX hardware, OpenVMS, with its DECnet networking protocol, has created a loyal user base. Customers are pleased by its reliability, robustness, security, and performance, and OpenVMS continues to perform demanding tasks at installations throughout the world. Even though some users may elect to migrate away from OpenVMS to some other environment, such as Linux, Windows, or UNIX, many users plan to continue running OpenVMS for years to come. Migrating from DECnet to TCP/IP for networked applications is a viable option that will permit users to continue to operate on OpenVMS and to do so without wide area DECnet support.
