Turning an Incident Report into a Design Issue with TLA+

Explore how modeling-driven techniques can enhance postmortem analysis of high-impact outages in this 31-minute conference talk from SREcon23 Americas. Learn about the application of TLA+, a formal specification language, to precisely describe and analyze the behavior of micro-service architectures under concurrency. Discover how building a specification of Microsoft's CosmosDB helped identify the root cause of a long-lasting outage, uncovered bugs in documentation, and provided insights into underlying design issues. Gain valuable knowledge on using TLA+ to create precise and reusable specifications, potentially preventing similar incidents in the future and improving overall system reliability.
