SELECTING SERVER RESOURCES FOR VIRTUAL DESKTOP INFRASTRUCTURE DEPLOYMENT
Virtualization as a technological base of Cloud Computing technology provides significant economic and social advantages for educational institutions. While using server virtualization and centralized management of desktop computers server resources consolidation combined with desktop virtualization facilitates the transition to a new level of IT service delivery. Both server virtualization and desktop virtualization raise the problem of resource usage optimization. The problem of hardware selection for Virtual Desktop Infrastructure deployment is reviewed in the article. The possibility of applying methods of integer mathematical programming to the problem of virtual machines placement on heterogeneous hardware platforms is thoroughly analyzed. A mathematical model of server platform and RAM selecting for placement of predetermined number of virtual machines with specified RAM requirements, objective functions and constrains are suggested. Problem solution for the proposed range of hardware server models and different numbers of hosted virtual machines are introduced
