Complexity

*A Philosophy of Software Design* — John Ousterhout

definition, prerequisites, experiment design, injection types (Chaos Monkey/Latency Monkey/FIT), targeting strategy, automation and moderation, disaster simulations; theoretical foundations (drift into failure, regulator paradox, antifragility); complex systems foundations (accidental vs essential complexity, emergent failures, composability of safety); Netflix origin story; Chaos Maturity Model

*Chaos Engineering: System Resiliency in Practice* — Rosenthal & Jones (eds.); complex systems theory, Five Advanced Principles, Game Days, LDFI, Chaos Maturity Model, Continuous Verification, Security Chaos Engineering, organisational/human factors

Ousterhout's complexity definition: three symptoms (change amplification, cognitive load, unknown unknowns), two causes (dependencies, obscurity), incremental accumulation; strategic vs. tactical programming; technical debt as borrowed time
