Cloud Computing Explained: Implementation Handbook
for Enterprises by John Rhoton
ISBN: 0956355609
Cloud Computing Explained provides an overview of Cloud
Computing in an enterprise environment. There is a
tremendous amount of enthusiasm around cloud-based
solutions and services as well as the cost-savings and
flexibility that they can provide. It is imperative that all
senior technologists have a solid understanding of the
ramifications of cloud computing since its impact is likely to
permeate the entire IT landscape. However, it is not trivial
to introduce a fundamentally different service-delivery
paradigm into an existing enterprise architecture.
This book describes the benefits and challenges of Cloud
Computing and then leads the reader through the process of
assessing the suitability of a cloud-based approach for a
given situation, calculating and justifying the investment
that is required to transform the process or application, and
then developing a solid design that considers the
implementation as well as the ongoing operations and
governance required to maintain the solution in a partially
outsourced delivery model.
