Multi-access edge computing system having fault prevention function and method for preventing failure thereof

A multi-access edge computing (MEC) system with fault-tolerant functionality, which enhances the performance of applications and services by deploying computing resources at the edge of the network, comprising:

• a first MEC service unit comprising a main service application, which acts as the primary provider of a service;
• a second MEC service unit comprising a first replicated service application, which acts as a backup in case of a fault in the main service application;
• a third MEC service unit comprising a second replicated service application, which acts as a backup in case of a fault in the main service application;
• and
• a fault-tolerant system comprising:
• a fault detection unit for detecting whether a fault has occurred in the main service application;
• and
• a fault adjustment unit for determining whether to replace the functionality of the main service application with one of the first or second replicated service applications in the event of a failure in the main service application.
