  Cloud services have been used very widely, but configuration of the
parameters, including the efficient allocation of resources, is an important
objective for the system architect. The article is devoted to solving the
problem of choosing the architecture of computers based on simulation and
developed program for monitoring computing resources. Techniques were developed
aimed at providing the required quality of service and efficient use of
resources. The article describes the monitoring program of computing resources
and time efficiency of the target application functions. On the basis of this
application the technique is shown and described in the experiment, designed to
ensure the requirements for quality of service, by isolating one process from
the others on different virtual machines inside the hypervisor.
