Fault Tolerant Systems
Fault tolerant systems are designed to continue operating properly in the event of the failure of some of their components. This is achieved through redundancy, error detection, and recovery mechanisms that prevent system-wide failures from single points of failure. The goal is to ensure high availability, reliability, and data integrity even when hardware, software, or network issues occur.
Developers should learn about fault tolerant systems when building mission-critical applications where downtime or data loss is unacceptable, such as in financial services, healthcare, aerospace, or telecommunications. Understanding these principles is essential for designing distributed systems, cloud-native applications, and infrastructure that must meet strict service level agreements (SLAs) for uptime and reliability.
