Then a dependency timed out, retries piled up, threads exhausted, and a partial outage became a total one. The failure mode was predictable-if you had designed for it.Systems that survive production are designed to fail gracefully. The rest discover their weaknesses during incidents.75 principles. Zero hand-waving. Each follows the same rigorous format: a clear explanation, warning signs that reveal violations, and markers that confirm correct application. No it depends without explaining why.Three chapters cover: Resilience and fault tolerance-circuit breakers, bulkheads, backpressure, and chaos engineering that keep partial failures from cascadingSecurity-zero trust, least privilege, defense in depth, and the access control models that limit blast radius when breaches occurTesting-TDD, property-based testing, contract testing, and the test pyramid that catches bugs before production doesFor engineers building systems that must work correctly under adversarial conditions-whether the adversary is a failing dependency, a malicious actor, or an overlooked edge case.Quality and Protection is Book 4 of the Software Development Principles series. Language-agnostic. Framework-independent. Built to last.Quality is not an afterthought. Protection is not optional. This book shows you how to build both in from the start.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/824/927/9798249278236_b.jpg", "price_data" : { "retail_price" : "54.95", "online_price" : "54.95", "our_price" : "54.95", "club_price" : "54.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
