Information technologies of application architecture`s IT services

Abstract

The development of the System Architecture of the IT infrastructure focused on the usage of modern Data Centers is considered. The purpose of the research is to develop a strategy for the development of the System Architecture of the IT infrastructure based on the usage of advanced methodologies and concepts of leading manufacturer’s hardware and software. The following principle of IT infrastructure construction is formulated: 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 technically good condition: 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. One of the most important architectures is the architecture of software applications. The architecture of software applications is determined by the business needs of the corporation and the approaches, methods of creating applications by a specific developer. It defines the execution environment for applications, mechanisms of communication between applications and components, tools for controlling the application and managing its state, as well as storage for structured and unstructured data types. Tasks of the architecture: to provide an environment for the execution of application components; support dispatching mechanisms for communications between application components; implement tools for monitoring the level of services and diagnosing problems; provide storage of structured and unstructured information. Standardization of the application architecture allows you to minimize costs associated with the support of several types of architectures, each for a specific type of business application.
