Do Legacy Systems dream of Modernization?
summary
About 30–40% of enterprise tech counts as legacy and consumes roughly 80% of budgets, often holding decades of irreplaceable data and code with lifespans far beyond the typical 6–8 year design assumption. Practical modernization leans on incremental wins delivered in 2–3 sprints, domain workshops that produce actionable roadmaps, and three proven patterns: strangler fig (build spring boot microservices beside the monolith), legacy mimic (implement existing contracts), and revert to source (cut out the monolith and query origin systems). 66% of change initiatives fail so start small and measure.
