The article discusses methods for increasing fault tolerance in systems with a hybrid architecture that includes elements of cloud technologies, local servers and peripheral computing. The main attention is paid to the analysis of vulnerabilities and risks inherent in such systems, as well as practical methods of their elimination. Both traditional methods such as hardware duplication and software redundancy are discussed, as well as modern approaches including the use of sharding, data replication, load balancing and integration of hardware and software. The article also highlights the importance of using preventive measures to minimize the risks of failures and the use of tools for modeling and testing failures. The work focuses on the need for an integrated approach to ensuring fault tolerance, taking into account both technical and economic aspects.
