The article represents the model of cluster platform of information network of a university with the aim of its optimization. The research is devoted to the improvement of efficiency and simultaneous access to web-services and databases in the learning process. The cluster is organized as a logically combined group of servers. They are able to handle the requests, received from users, and are used as a single resource. The implementation of the cluster is carried out mainly using LAN of a university. The total time of processing of server requests is set by the method of its maximum load at simultaneous requests of users to the file server with a set of databases. It provides access to resources, handles a lot of traffic, and stores a large volume of files and archives. The realization of remote access to the dataware systems depends on the access speed to the file server. The generation of packages was carried out by connecting the servers of various departments to the switches that generate traffic to the desired address and specified port. The usage of few operation processes, on the one hand, reduces the load on each specific process. On the other hand, the launching of the set of processes allows the efficient use of hardware resources of working server. Besides, the launching of the set of processes improves the reliability of the server, having isolated the groups of clients, working with different infobases. In a cluster, where the launch of the set of processes is possible, each of them can be automatically restarted after the time, specified by the administrator of the cluster, is completed.References
