Enterprise architecture (EA) is like the master plan for an organization, a comprehensive strategy that shapes how it functions. It's the blueprint that aligns all aspects of the business, from its processes and information systems to technology infrastructure and human resources, with the overarching goals. Business architecture dives into strategy and organizational structure, understanding how the different parts of the business work together. Information architecture manages and structures data, ensuring it supports business processes. Application architecture organizes software applications to align with business needs, while technology architecture looks after the hardware, software, and networks. Security architecture safeguards information assets, and integration architecture ensures seamless communication among various systems. Essentially, EA is the guiding force that ensures everything within an organization works in harmony toward its objectives.
