Explore strategies for implementing continuous delivery in legacy codebases through this conference talk from NDC London 2024. Dive into a real-world case study of a complex, multi-language monolith with 5 million lines of code and no existing best practices. Learn how to identify hotspots, uncover hidden coupling, leverage connascence, implement testing strategies, and refactor effectively. Discover practical techniques for transforming a challenging legacy system into one capable of bi-weekly deployments with high confidence. Gain insights on software archaeology, code recovery, and modernization applicable to your own legacy code challenges.
