Cloud computing technologies in “smart city” projects

The experience of cloud-based computing technologies use in the Smart City class design is analyzed. In the considerable part of applications in the Smart City class design informational technologies of cloud-based computing combined with such technologies as GRID, IoT, BigData, OLAP, GIS are used. At the same time complex solutions systematically considering peculiarities of defined technologies are practically non-existent. To introduce the Smart City concept it is necessary to realize completely the system approach considering peculiarities of existing IT infrastructure and appropriate services. In such a case interests of a wide range of motivated organizations, companies, firms and great number of town residents should be taken into account as far as distinction of informational resources access rights are concerned. Layer architecture of the Smart City class informational system for accumulation and processing of diverse data obtained from intelligent providers were analyzed by the authors during the research. Characteristics and realization of informational technologies on the basis of cloud-based computing used in Smart City designs were reviewed. In further investigations it is reasonable to model system operation and develop its prototype for individual water and heat cost accounting as well as operational mobile customer accounts for received services. It is also necessary to establish possibilities of functions increase and integration with other subsystems of “Smart City Ternopil” design portfolio.
