Deep dives
Understanding Resilience in Software Systems
Resilience in software engineering is essential for maintaining systems' reliability and performance. The discussion emphasizes the importance of differentiating between terms associated with system robustness, such as resilience, reliability, and robustness itself. The conversation reveals that many of these concepts rarely consider the role of human operators in system management, which is crucial in sociotechnical systems. Recognizing the human element helps build a more complete understanding of how systems function and the consequences of outages or failures.
