Evaluation of the effectiveness of fault tolerance methods in the internet of things networks

This essay represents an analysis of the effectiveness of methods for ensuring fault tolerance of IT infrastructure, as well as an evaluation of these methods in relation to industrial Internet of Things networks. The IT infrastructure of an organization can be divided into 3 expanded objects - network equipment and software, hardware complex, software complex. To maintain the workability of the entire system, relevant groups of fault tolerance methods can be identified, as well as such methods that relate to two or three objects at once - network separation, the use of communication protocols, fault-tolerant servers and load balancers, backup and regular software updates, personnel training, as well as the use of monitoring and notification systems. For full-fledged functioning without failures and rejections, the systematic application of the above methods is necessary. The article presents a proposal for the selection of measures based on expert evaluation and the application of specific measures, the choice of which is determined by the results of the proposed matrix. The aim of this work is to analyze and determine the methods of ensuring fault tolerance that are most suitable for organizations that use the technology of the industrial Internet of Things. Theoretical and empirical methods of scientific research were applied in the study, in particular analysis, synthesis, thought experiment, expert evaluation. The result of the work is a suggestion for system fault tolerance in relation to industrial Internet of Things networks.
