At some point most of us will face the critical decision of whether to modernize a legacy system or rebuild it from scratch. While these decisions can make or break budgets and careers, they are often driven by emotion, outdated assumptions and optimism, rather than facts, data and clear rationale.

This talk explains how an architecture-driven approach can help address the renovate-versus-rebuild dilemma, by moving beyond assumptions to use a decision framework based on proven architectural knowledge.

Whether you're facing a creaking monolith today or are drowning in distributed technical debt, this session will give you a starting point and an approach to to make and defend your own legacy system decisions with confidence.
