In this article, the solution to the problem of ensuring the ecological improvement of water bodies, including the Volga River, and the preservation of unique water systems, including lakes Baikal and Teletskoye, is reduced to the creation of a digital monitoring system capable of organizing communication with a large number of devices for monitoring the environmental parameters of lakes and rivers. On such a scale, a well-planned platform will avoid problems in data exchange, provide fast and timely access to information. When creating a platform of this type, a number of requirements and tasks arise, the solution of which can cause certain problems and limitations. To organize a stable connection with monitoring devices in the amount of several million pieces, the IT platform must be scalable and performant. These and other tasks are being solved by the Irkutsk National Research Technical University together with the STC “Kumir”.
