We then used simple thought exercises based on flipping coins to build intuition around false positives and related concepts such as statistical significance, p-values, and confidence intervals. As a result, if the test treatment results in a small reduction in the latency metric, it’s hard to successfully identify?

A resilient system continues to operate successfully in the presence of failures. There are many possible failure modes, and each exercises a different aspect of resilience. Hence, one way to reduce risk is to make systems more observable. This discussion focuses on hardware, software and operational failure modes.
