Katkestuskindlus, a Finnish term, translates to "fault tolerance" in English. It refers to the ability of a system, such as a computer system or network, to continue operating correctly even when one or more of its components fail. This is a crucial characteristic for systems that require high availability and reliability.

Achieving fault tolerance typically involves redundancy. This means having duplicate components or systems in place so that if one fails, another can take over its function without interruption of service. Redundancy can be implemented at various levels, from individual hardware components like power supplies and hard drives to entire servers, data centers, or network links.

Beyond hardware, software can also be designed with fault tolerance in mind. This might involve implementing error detection and recovery mechanisms, designing self-healing systems, or employing distributed computing architectures where data and processing are spread across multiple nodes. The goal is to minimize downtime and data loss in the face of unexpected failures.

The level of fault tolerance required for a system depends heavily on its intended use. Mission-critical applications, such as those in financial trading, healthcare, or emergency services, demand very high levels of fault tolerance to prevent catastrophic consequences. Less critical systems might tolerate a greater degree of downtime. Implementing fault tolerance often involves a trade-off between cost, complexity, and the required level of resilience.
