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.

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.
