Today, modern business is adrift in a sea of connectivity and potential. Where once an organization’s IT needs could be met from within its four walls, we now see many mission-critical systems reaching out beyond an enterprise’s traditional boundaries. This is pushing solutions design well beyond the comfort zone of Enterprise Architecture and out into a world of hyper-enterprise systems. This is a world of complexity and scale, where the changing status quo demands that organizations keep up or die. To survive, their IT systems must also evolve as the context of their environment(s) ebbs and flows. The result is a dynamic, interconnected web of critical business advantage, balanced against uncertainty and risk, and infused with AI. This is the world of Ecosystems Architecture. This book will introduce you to the challenges of designing hyper-enterprise IT systems and the tools you will need as the era of Ecosystems Architecture dawns. It explains the proximity of new thinking to long-held architectural tenets and outlines how and why thinking has moved on. It also reviews existing frameworks and explains how and why they fit into the broader landscape of architectural thinking.
