Bukasov M. The information technology for IT-infrastructure load and resources management

The dissertation work is devoted the decision of important science problem of development of methods, models, algorithms and complex tool for IT-infrastructure load and resources management. The original complex of models and algorithms for IT-infrastructure load and resources management is developed, which recovers the necessities of management taking into account the scales of IT-infrastructure, technologies, stages of life cycle of services, level of providing and level of resources abstraction. The guided genetic algorithm is offered for an effective management convergence at the search of decisions, which differs from existing by influence on the order of implementation of operators on previous iterations results, which allows improving speed of solving. Modification of serial analysis of variants is developed taking into account symmetry of decisions for the case of server virtualization on the cluster systems, which allows substantially decrease the amount of variants, which must be analyzed. Information technology of management loading and resources of IT-infrastructure is developed on the basis of models and algorithms complex, which allows reacting flexibly on changeableness of terms, in particular requirements of users.
