In June 2005, Nitix Virtual Server was released, which allowed for the hosting of applications on its system. The architecture for the application services on Nitix allowed for applications to run in a virtual server environment, completely separated from the controlled OS environment. The Virtual Server is an RPM based filesystem which incorporates Yellow dog Updater, Modified as an application retrieval tool. Simultaneously Net Integration Technologies began sponsoring a "Ready For Nitix" program that encouraged independent software vendors to certify applications under Nitix. Also in June 2005, Nitix began to support NS3 (Scalable Services Structure), which allows for the centralized user management across multiple servers, as well as DNS propagation.
