Failais
Failais is a term used in the study of failure in complex, interdependent systems. It denotes a class of outages that originate from interactions among multiple components, services, and data flows, rather than from a single defective part. The concept is used to analyze how small faults can escalate into broader system degradation.
Definition and scope: Failais describes cascade-like failures that spread through networks such as distributed computing platforms,
Causes and contributing factors: Triggers include asynchronous messaging delays, shared-resource contention, partial failures of services, inconsistent
Mitigation and design: Approaches include strong fault isolation, idempotent operations, explicit timeouts and backoff strategies, circuit
Impact and study areas: Failais is discussed in cloud infrastructure, critical systems, and large-scale software environments
