Beyond Goldilocks Reliability

Explore the concept of reliability engineering in this 39-minute conference talk from SREcon21. Delve into the limitations of current best practices and the "Goldilocks approach" to reliability. Examine a concrete model for framing reliability and its implications for answering complex questions about services. Investigate why certain mitigation strategies are effective and how aggregation and backend drains contribute to reliability. Learn how to identify underlying mechanisms to reinforce desired reliability properties and develop new mitigation strategies. Discover the concept of reliability modeled as stationarity and its practical applications in hierarchical diagnostics and exposing reliability phenomena. Gain insights into the future capabilities of reliability engineering and draw conclusions for improving current practices.
