Most software architectures are still expressed in static diagrams and documents that can't be tested or automatically verified. As organizations grow, this gap between design and implementation leads to drift, manual governance, and mounting complexity. Architecture as Code offers a new approach: defining architecture itself in executable form.Acclaimed software architects Neal Ford and Mark Richards present a practical framework for treating architecture like source code—using fitness functions and automated feedback to define structure, constraints, governance, security, and communication across the entire organization. By capturing these intersections in code, teams can continuously validate alignment with technical and business goals, reduce risk, and evolve systems with confidence.This is your go-to guide for making architecture measurable, verifiable, and adaptable at scale. With clear examples and proven practices, this book shows you how to:Define architectural decisions and constraints as codeContinuously test and validate architecture across implementation, infrastructure, and teamsAlign architecture with business objectives and compliance requirementsEstablish a governance mesh that unifies constraints across multiple intersection pointsLeverage generative AI to help craft and evolve fitness functions
