The article substantiates the need to use the methods of economic and mathematical modeling in studies of sustainable development, both at the regional level and at the state level. The authors propose a model for determining the level of sustainability of regional development, implementing a boundary approach for calculating the sustainability corridor considered in the dynamics of key indicators.

The issue under study is pressing due to the high importance of information and communication technologies for the future of Russia that establishes new requirements for priorities in regional development strategy. The role and importance of information and communication technologies for the development of Russian economy are defined. The problem of imbalance in territorial economy structure which is typical for Russia as a multi-regional economic system leads to the need for a comparative analysis of regions in terms of development level and using information and communication technologies. The multivariance of studied process requires using special methods which include cluster analysis used by the authors; it is one of the methods of multivariate statistics and reflects the features of multivariance during the procedure of classifying objects. Clustering procedure was performed by the authors on the basis of hierarchical agglomerative methods using Euclidean distance between objects and farthest neighbor method in order to calculate the distance between clusters. In addition, the stability of obtained clustering results was checked using k-Means, Centroid, and Median methods. In order to get a dynamic clustering picture, we compared the results of dividing regions into clusters according to statistics from 2014 and 2017. Additionally, a comparative analysis of the regions was carried out according to the level of development of information and communication technologies based on the integrated comparison parameter developed by the authors.

The article substantiates the need to choose a new paradigm for the macro-regional development of Eurasia, which, along with other macro-regions, has found itself in recent decades in a situation where the old theoretical platform for regional development has ceased to correspond to modern conditions of economic and socio-political reality. The system paradigm proposed as an alternative puts forward the principle of studying the region as a holistic system based on the analysis of interconnections and relations between its individual components. This applies both to the internal relations of the system (economic, cultural, organizational, demographic, social and others), as well as interconnections with the environment external to the system. According to the authors, the growing role of economic sustainability is determined by the objective need to develop theoretical, methodological, and practical guidelines that would enable the process of transition to a sustainable development format.

This article discusses the use of microservices in the context of HR processes and proposes a specific architecture to achieve this goal. The article is of interest to everyone who is interested in improving processes using the latest technologies.
