Enterprise Architecture (EA) is the technical fabric of an enterprise. However, EA also transcends technology and moves into business space. Therefore, EA needs to be discussed in an integrated, holistic manner. Only such an integrated EA can provide the necessary basis for a business transformation that makes the business ready for the myriad business and technological challenges it will invariably face. For example, Big Data, mobile and cloud computing are all highly disruptive technologies that require a fine balance between their business and technical aspects as the organization moves forward. The book focuses on preparing organizations for the impact of these disruptive technologies.
