Architecture Modernization

By Nick Tune

Nick Tune tackles the challenge that nearly every growing organization faces: how to modernize a legacy architecture without stopping the world. The book goes beyond just technical strategies, emphasizing the socio-technical approach — aligning software architecture with business domains, team boundaries, and organizational strategy.

Drawing on domain-driven design, wardley mapping, and event storming, Tune provides a practical playbook for assessing your current architecture, building a modernization strategy, and executing incrementally. If you've ever struggled with migrating a monolith, untangling coupled services, or getting stakeholder buy-in for architectural change, this book offers the frameworks and case studies to guide the way.
