Unbreakable by Design: The Secret Tech of Antifragile Software
summary
Explains how antifragile software actually works: a write‑ahead log with Kafka‑backed durable queues, Redis cache and per‑service shards removes single points of failure and lets incidents be recorded to improve behavior; recommends concrete patterns — circuit breakers, adaptive retries using observed interarrival distributions, timeouts, fallbacks and diversity/redundancy — and tooling: Resilience4j, Kafka, Redis, PostgreSQL/Mongo. Describes runtime fault injection via AspectJ pointcuts to mutate delays, errors and payloads for Spring apps, and cites LLM‑based automated patching pipelines that fix ~15% of bugs.
