The article discusses the topical issue of creating a technologically integrated network of data centers built on a single virtualization platform to support the functioning of IoT infrastructures. A comprehensive solution for the interaction of all IIoT / IoT components is proposed, based on three types of platforms. The role of Data centers of each type is substantiated depending on geographical, economic and branch peculiarities of the Russian Federation. An analysis of wireless technologies for the transmission of small amounts of data over long distances in the context of their current and projected use for IIoT / IoT in Russia is being conducted. In particular, the draft of the Russian communication standard for the Internet of things NB-FI is being analyzed. The structural scheme (model) of the decision on the organization of the Control Center IIoT / IoT is offered.

The relevance of the formation of the national digital economy is confirmed by the presence of global trends of digitalization of the international society and the need to preserve digital sovereignty of Russia. The article analyzes the subindexes of the international Networked Readiness Index (NRI) and identifies the factors that have affected Russia's lag in the network readiness rating in order to understand the problems of transition to the digital economy and determine the ways to solve them. Ways to prevent threats to information security are suggested.

The article presents an analysis of the level of security of the Russian subway in comparison with European and American. The modern mobile Wi-Fi network of the Moscow subway, its advantages and known cases of attacks are considered. Highlighted the problematic issues of cyber security, which need to be addressed in security audits and in the process of creation and development of special operations centers to respond to cyber attacks. A model of a prospective center for early warning of group and mass cyber attacks on critical transport infrastructure is proposed.

The article discusses the end-to-end business concept of governance of information technology in the context of e-commerce enterprises as a sector of the digital economy that needs to improve the quality of management and training of targeted personnel. Processes for governance of enterprise IT were considered in accordance with the COBIT 5 methodology. Analysis and selection of IT enterprise management processes in e-commerce was carried out. An adapted CobiT model for ecommerce enterprises and a graphical model of the space of topics and competencies for learning in the digital economy are proposed.

This study presents the results of the development of numerical models for predicting the timing of apricot flowering, including using experimental data on the emergence of plants from a state of deep dormancy. The best results of approximation of the process of accumulation of the necessary cooling in the autumn–winter period were obtained using the sigmoidal function. Models that take into account the combined effect of temperature and photoperiod on the processes of spring development showed a high accuracy of the process of accumulation of thermal units. Based on the results of testing, two models were selected with an accuracy of 3.0 days for the start of flowering and the absence of a systematic bias, which can be considered a good quality assessment These models describe well the interannual variability of apricot flowering dates and can be used to predict these dates. The discrepancy is no more than 2–4 days in 87–89% of cases. Estimates of the timing of flowering and the end of deep dormancy are very important for increasing the profitability of fruit production in the South of Russia without incurring additional costs, by minimizing the risks associated with irrational crop placement and the selection of varieties without taking into account the specifics of climate change. When constructing a system of protective measures and dates of treatments, it is also necessary to take into account the calendar dates of the shift in the development of plants.
