Unlocking Value from Legacy Technology
summary
Argues organisations extract value by stabilising legacy, adding automated tests and an API layer, then incrementally routing traffic to new services — Trainline takes five years of work to move from brittle J2EE to continuous delivery. Recommends AWS-managed services to cut rewrite cost, microservices built around business domains rather than legacy data models, and using a thin slice to prove complexity quickly. Describes creating a separate unit — a new co or digital team — that launches modern cloud products (Barclaycard example) and pulls the rest of the organisation forward.
