Renovate to Innovate: Fundamentals of transforming legacy architecture
summary
Claim: legacy systems are a predictable byproduct of growth and are defined as systems incapable of keeping up with business requirements. Concrete strategies: prioritize make it work, make it right, make it fast; apply evolutionary architecture with measurable fitness functions, CI/CD automation and incremental releases; use deprecation-driven development to retire low-ROI components; align team structure with architecture per Conway’s Law. Evidence includes Netflix’s DVD→streaming shift and Amazon’s finding that every 100 ms latency costs ~1% in sales.
