What is an Enterprise Architecture?
At its core, enterprise architecture (EA) is the discipline of aligning business and IT to achieve long-term transformation. It ensures that people, processes, and technology work in harmony. When organizations ask, “what is an enterprise architecture?”, the answer lies in understanding the enterprise architecture layers—the building blocks that structure how enterprises plan, model, and execute their strategy.
Understanding Enterprise Architecture Layers and Domains
Enterprise Architecture is typically divided into four primary domains (often called the enterprise architecture layers):
Business Architecture Layer
Captures strategy, value streams, capabilities, and processes.
Application Architecture Layer
Defines the systems, services, and integrations that support the business.
Data / Information Architecture Layer
Structures how data is modeled, governed, and shared across the enterprise.
Technology Architecture Layer
Details the infrastructure, platforms, and networks that power the applications and data.
