Fault Tolerance is the ability of a system or infrastructure component to continue operating and providing normal functionality even in the event of errors, failures, or other negative impacts.

The main goal of fault tolerance is to ensure the stable operation of the system even in the face of potential technical problems. This is achieved through resource redundancy, task distribution among different system components, and the implementation of automatic error detection and correction mechanisms.

Fault tolerance is important for ensuring the continuity of business processes and reducing the impact of unforeseen situations on the performance of information systems. This approach allows for a high level of availability and reliability of services.
