Information Technology / Software Engineering & Systems Development R Cloud a … a useful source of information for enterprise architects, managers, and directors j of organizations, as well as students and researchers in the fields of Cloud computing and EA. It provides a thorough and timely investigation of the convergence of Cloud Enterprise computing, on one hand, and enterprise data, applications, and infrastructure architectures, on the other. … a welcome addition to the body of existing knowledge in these fields and emerging new technologies. —Zaigham Mahmood, School of Computing and Mathematics, University of Derby, UK Architecture Cloud Enterprise Architecture examines enterprise architecture (EA) in the con- text of the surging popularity of Cloud computing. It explains the different kinds C of desired transformations the architectural blocks of EA undergo in light of this strategically significant convergence. Chapters cover each of the contributing archi- l tectures of EA—business, information, application, integration, security, and tech- A o nology—illustrating the current and impending implications of the Cloud on each. ru Discussing the implications of the Cloud paradigm on EA, the book details Pethuru Raj c the perceptible and positive changes that will affect EA design, governance, d strategy, management, and sustenance. The author ties these topics together with h chapters on Cloud integration and composition architecture. He also examines the E Enterprise Cloud, Federated Clouds, and the vision to establish the InterCloud. i Laying out a comprehensive strategy for planning and executing Cloud-inspired t n transformations, the book: e • Explains how the Cloud affects and changes enterprise architecture t c design, governance, strategy, management, and sustenance e t • Presents helpful information on next-generation Cloud computing r u p • Describes additional architectural types such as enterprise-scale integration, security, management, and governance architectures rr ei This book is an ideal resource for enterprise architects, Cloud evangelists and s enthusiasts, and Cloud application and service architects. Cloud center adminis- trators, Cloud business executives, managers, and analysts will also find the book e helpful and inspirational while formulating appropriate mechanisms and schemes for sound modernization and migration of traditional applications to Cloud infrastructures and platforms.
