CORE DEFINITION

Site Reliability Engineering. It introduces software engineering methods into operations. The core idea is: operations problems are software problems, and they should be solved with code, not by adding more people.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Automation as a forcing function. If you are doing repetitive operational work (Toil), according to SRE principles, you must stop and write code to automate that action. Limit the proportion of time spent on manual operations (e.g., 50%).

anchor

Anchor fast decisions

Use software engineering methods for operations: treat stability as an engineering problem measured by available SLI/SLO, use automation to eliminate repetitive manual labor (Toil), and use Error Budget to balance between 'stability' and 'speed'. The core idea is 'operations problems = software problems', solved with code rather than by adding more people.

Rational Irrationality

Caplan’s explanatory framework: people may relax truth-seeking standards when appealing beliefs bring psychological benefits and the private marginal benefit of correcting errors is low.
