Architecture of Digital Economy

The new high-quality level of information and communication technologies, their standardization and massive implementation ensure a passage to a new stage in the development of the information society - to digital economy, which has become the political, economic and cultural purpose of all developed countries of the modern world. The move towards this purpose is supported by government programs, development programs of regions and national economy sectors and a large number of other initiatives. Building a digital economy involves solving a number of problems, which have one common root cause - cardinal change of information communication technologies. In process of practical movement to new principles of management the contradiction between private and general approaches to their introduction becomes more acute. On the one hand, we can see financial growth of an increasing number of local tasks, the development of certain technologies, pilot projects and start-ups, and, on the other hand, insufficient attention to the development of an integrated systematic approach to the study of the digital economy as a holistic technological project that uses generalized information models and architecture. It's clear that without studying the properties of the digital economy as a large digital information system, it is impossible to form new markets and activity models in any of the application areas. The problem solved in the article is to resolve this contradiction. Goal of the work - the construction of an architectural model of a digital economy that unites the entire set of fundamental principles of its technological organization that are embodied in a set of digital technologies, the connections of technologies with each other and with the external environment. The following tasks are solved: the properties and attributes of the digital economy are analyzed,; precondition of the architectural description of the digital economy are identified,; a stratified architectural model of digital economy is developed. It is shown that the architectural model of the digital economy must contain infrastructure and subject-oriented levels. The first group includes physical laws and technologies for constructing real and virtual digital datal sources, networks and storing systems, data processing and distribution, as well as cloudy and foggy computing. The second - technologies for creating structures and data analysis, building digital platforms and applications, creating a digital platform ecosystem, digital markets and business processes models. The methodology of the conducted research uses the principles of designing models system developed in the construction of digital infocommunications systems architectures; cloud computing, industrial Internet, big data, overlaid services and other technologies of the third informatization platform. The methodology used made possible to divide the entire complex process of creating the digital economy into simple parts - levels and subprocesses, development common concepts and terminology, highlight the basic functionality of technologies to all hierarchy levels, formation of the core specialists competencies who study and implement different subprocesses, simplify the organization task of the interaction of products that implement subprocesses, etc.
