Virtual servers (VPS)
Virtual servers (VPS) based on cluster systems are service, reliable and available to the client. The cluster system allows to balance load of the server, to redistribute it and to reduce failure probability to a minimum. During the carrying out technical works or failure of the server there is "moving" of data from one server of a system on another, without loss of quality of service.
Such operation of virtual servers is convenient especially when carrying out updates of a system and applications. System performance of clusters is much higher, than at the separate server that also increases reliability of service.
Virtual servers easy to control, and access to them is provided both locally, and far off, by the administrator. It is possible to manage the server by own forces or using the administrator of the company.
Administration of servers is an additional opportunity for clients of the company. Important point is cost – it 10 times less the cost of similar service at lease of the physical server.
