Methods of Creating Fault-Tolerant Geographically Distributed Systems

The fault - tolerance of information systems is of great importance for achieving the required level of reliability. The need to ensure a high level of system stability especially increases (with an increase in the number of clients). Today, many tools have been created and approaches have been developed to ensure a high level of fault - tolerance [9-11]. In this work, some of the promising approaches are considered, using which a geographically distributed system was developed and launched that provides unified access to the API of trading platforms. The emphasis is not on detailed instructions for creating the system, but on the key points and tools.
