This is the Safari online edition of the printed book.

 “In this book, David Linthicum does that rarest of things: he manages to combine showing why SOA and Cloud Computing complement one another with a lucid game plan of how a business can take advantage of the synergies between them in concrete ways that will contribute to the bottom line.”

Massive, disruptive change is coming to IT as Software as a Service (SaaS), SOA, mashups, Web 2.0, and cloud computing truly come of age. Now, one of the world’s leading IT innovators explains what it all means—coherently, thoroughly, and authoritatively.

Writing for IT executives, architects, and developers alike, world-renowned expert David S. Linthicum explains why the days of managing IT organizations as private fortresses will rapidly disappear as IT inevitably becomes a global community. He demonstrates how to run IT when critical elements of customer, product, and business data and processes extend far beyond the firewall—and how to use all that information to deliver real-time answers about everything from an individual customer’s credit to the location of a specific cargo container.

Cloud Computing and SOA Convergence in Your Enterprise offers a clear-eyed assessment of the challenges associated with this new world—and offers a step-by-step program for getting there with maximum return on investment and minimum risk. Using multiple examples, Linthicum:

• Reviews the powerful cost, value, and risk-related drivers behind the move to cloud computing—and explains why the shift will accelerate

• Explains the technical underpinnings, supporting technologies, and best-practice methods you’ll need to make the transition

• Helps you objectively assess the promise of SaaS, Web 2.0, and SOA for your organization, quantify value, and make the business case

• Walks you through evaluating your existing IT infrastructure and finding your most cost-effective, safest path to the “cloud”

• Shows how to choose the right candidate data, services, and processes for your cloud computing initiatives

• Guides you through building disruptive infrastructure and next-generation process platforms

• Helps you bring effective, high-value governance to the clouds

If you’re ready to begin driving real competitive advantage from cloud computing, this book is the start-to-finish roadmap you need to make it happen.

Cloud Computing - 2009-11-10
Reviewer Rating:
In looking at the world of cloud computing, and thus cloud computing
books, this book stands out in that it talks about how something is
done, versus what it is. There is a huge difference.

I enjoyed the stepwise approach that this book takes, including
working from the requirements to the implementation.
Specifically, this book was able to explain the value of governance
in the context of cloud computing, and how architectures can exist
between enterprises and cloud computing providers.

I would urge you to read this book before starting on a cloud
computing project. I suspect that most will just dive right into
cloud computing without any architectural forethought. Clearly,
that is a big mistake.

Cloud Computing and SOA Convergence in Your Enterprise- A step by Step Guide David S. Linthicum Published by Addison-Wesley

The author takes a practical approach to a project role out. Often the pace of technology outstrips the best of us. This book is a great help. For those tasked with setting up a cloud environment, the book gives you a good road map. If you are new to the concept and just adding to your knowledge base, the content is easily understood. It does not matter if you are a CEO or a student; the take away is an insightful understanding of Cloud Computing in general and for the Enterprise in particular.

Discussed is why the cloud matters and when you should use it. Some books just hype the subject, not this one. Instead, you get a clear understanding on what your ROI should be and the potential pitfalls. The book also covers the planned migration, breaking down each service and testing.

I would recommend this book for any person with an interest in Cloud Computing.

With this book and its key knowledge, you can sling-shot your efforts and seize the moment - 2009-10-11

Good news! If you are an IT leader, developer, or architect, or a non-technical person for whom IT subjects are an important part of your work, this book is for you. I highly recommend it.

The book is written based on reality and in-depth experience rather than hype, buzz words, or the latest technological "flavor of the month." While accepting the reality of the Cloud, as the author puts it, "[this] is a book promoting good architecture practices by leveraging the best from Service Oriented Architecture (SOA) and Cloud computing." I agree wholeheartedly with this depiction. If you have to buy only one book on Cloud computing or its marriage with SOA, this is it!

David Linthicum, a renowned author and thought leader on the subject, is handing us vital knowledge about Cloud computing, all in one concise package. In addition, the informal writing style of the author makes the information more accessible to a wide range of readers. The more you read and learn about the subjects of Cloud computing and SOA , in general, the more you will realize that this book is an invaluable resource, whether this is your first book on the subject or you already have a stack of related books.

Just as the clouds in our planet's atmosphere are everywhere to a varying degree, right now, whether you are aware of it or not, Cloud computing is also everywhere in our computational life to a varying degree. We are only in the beginning of this computing Renaissance. I think that, just as in the actual history of the Renaissance, the changes in the IT world through Cloud computing will not be uniform across all markets. Some will benefit from it immensely, while others will lag behind. The knowledge handed to the reader through this book will help you to focus better and position you to take advantage of Cloud computing and SOA more quickly. As correctly pointed out by the book, in order to take full advantage of Cloud computing, we need architecture and discipline inside of the enterprise, such as SOA.

I agree with the author's description of his book that, "This is more than just a book that defines some technology; this book defines a class of technology as well as approaches and strategies to make things work within your enterprise." With this book and its key knowledge, you can sling-shot your efforts and seize the moment. The alternative is to go solo and, through trial and error, maybe get there eventually, after losing time and opportunities.

If you miss this book, you put yourself at greater risk of missing out on opportunities that are waiting for you out there.

I became a fan of David Linthicum's abilities to take complex topics and reduce them to understandable, logical flows after reading his book B2B Application Integration: e-Business-Enable Your Enterprise. And now, Cloud Computing and SOA Convergence in Your Enterprise: A Step-by-Step Guide serves up a crisp understanding of why cloud computing is critical, and where and how to apply it to gain true business benefits. I consider myself to be more of an operator, trying to follow the language and concepts that IT professionals use. Linthicum's books help me do just that, providing me an opportunity to explore more than the basic concept and leading me to a better understanding of where IT is taking future business.
