The development of the System Architecture of the IT-infrastructure focused on the use of modern Data Centers is considered. At the same time, it is envisaged to create components that describe: general approaches to building a system architecture; IT-services – information technologies that solve the task of providing IT-services; logical model of IT-infrastructure. Formulated logic of IT-infrastructure construction: IT-infrastructure architectures define a set of services. IT-services are provided to three groups of clients. IT-services and clients are connected by 5 implementation scenarios. The integration of IT-services is determined by 5 architectures. As IT-services, we understand information technologies aimed at maintaining the following elements in a technically good state: network devices, computing equipment, data storage devices, automatic software deployment services, network services, perimeter protection services, directory services, file and print services, data management services, business application services, IT-management services, archiving and recovery services, certificate management services, integration services. Architectures define the fundamental principles of building IT-services and their relationship. Also, requirements for the creation of IT-services are formed on the basis of the architecture. One of the most important architectures is architecture of IT-infrastructure management. The architecture of the management system ensures the necessary level of IT-services of the Data Center due to the organization of three components – personnel, processes, technologies. The tasks of the architecture are: use of processes and information technologies to identify and minimize failures of IT-services; ensuring a high degree of integration of information technologies; ensuring response to changes in system parameters and performance of service functions in real time. As an example, the management function of the IT-service “network administration” (monitoring and control of configuration management services, coordination of changes, remote management and debugging) is considered. The algorithmic synthesis of programs and devices network management is considered, which consists in the construction of a functional scheme of control devices in two stages – abstract and structural synthesis, and all the steps of its solution and subsequent hardware synthesis are determined.
