Principles of Fault Tolerance in IT Systems: A Review

Abstract

This study aims to thoroughly analyse the fundamentals of fault tolerance systems in IT systems. This study aims to give a general understanding of the concepts involved in fault tolerance systems. This research examines fault tolerance concepts in IT systems regarding fault isolation and online repair. Examining fault tolerance in the context of IT systems and going over fault tolerance strategies in fault isolation, online repair, and fault isolation are the key goals of this research topic. A variety of fault-tolerant strategies are applied to increase fault tolerance. Among these, fault isolation is essential to creating a highly available system with fault tolerance. Load balancing and failover techniques are also employed with fault isolation approaches for high availability.
