Reimagining Enterprise Architecture for the Cloud-Native Era is a guide for architects, engineering leaders, and technology executives navigating the shift from traditional, layered enterprise architecture to the distributed, dynamic realities of cloud-native systems.

For decades, enterprise architecture was built around assumptions that no longer hold: predictable release cycles, centralized infrastructure, tightly controlled change management, and systems designed to be stable rather than constantly evolving. Cloud-native computing — with its containers, microservices, event-driven designs, and infrastructure-as-code — didn't just introduce new tools. It rewrote the underlying assumptions about how systems fail, scale, and change, and in doing so, it exposed how much of classical enterprise architecture was built for a world that no longer exists.

This book argues that enterprise architecture doesn't need to be abandoned in the cloud-native era — it needs to be reimagined at the level of first principles. The discipline's core commitments — coherence across systems, alignment between technology and business strategy, sound governance — remain essential. What has to change is how those commitments are achieved when infrastructure is ephemeral, teams own their own services end-to-end, and delivery happens continuously rather than in scheduled releases.
