Why Is My App Slow - Defining Reliability in Platform Engineering

Explore a comprehensive conference talk on defining reliability in platform engineering, focusing on Google's Serverless SRE team's approach to detecting and measuring latency regressions. Dive into topics such as total latency distribution, request delivery latency, and the limitations of SLOs. Learn about the 2-Sigma Technique, overload scores, and impact analysis for tracking platform performance. Discover practical applications including streamlined diagnosis and approximate cohort A/B testing. Gain valuable insights into customer-centric performance measurement and statistical approaches to platform reliability from an experienced SRE at Google Cloud.
