The book provides systematic treatment of all aspects of a Cloud Computing implementation starting from a definition of what it actually means and assessment of whether it is suitable for a given company to the strategy alignment, implementation and operation of a working solution.

It covers some of the main concerns around cloud computing including risk assessments, governance models, compliance concerns, interoperability with existing and heterogeneous environments. While these are legitimate issues there are ways to address them which are explored extensively in the book.

It provides a very wide treatment of cloud computing that covers Infrastructure-as-a-Service, Platform-as-a-Service, Software-as-a-Service as the many integration and management components that are necessary to make these work together to fulfill business requirements.

It is not focused on any particular vendor or service offering. While there is considerable treatment of Amazon, Google and Microsoft the text references several dozen other players and demonstrates how the whole ecosystem works together to solve the main objectives of cost reduction, business flexibility and strategic focus.

What I liked most was that as an IT manager the book leads you through your whole cloud computing project. It provides methods and background information on how to tackle each project step best. It is a perfectly comprehensive implementation guide covering everything you need to be aware of.

John Rhoton's book "Cloud Computing Explained" is the best cloud computing book I've been able to find. Written in an easy-to-read format, which I like, it adopts Rhoton's proven approach at implementing emerging technologies in Fortune 500 corporations. The book is divided into ten logical sections that provide a thorough picture of cloud computing:

1. Define: explores the meaning of the term and its context; consider the different manifestations of private, public and partner clouds delivered as Software-as-a-Service, Platform-as-a-Service and Infrastructure-as-a-Service

2. Assess: provides a sober means to evaluate when and where it is applicable, considering financial, strategic and risk implications

3. Design: establish a high-level approach and methodology for evaluating, planning and implementing cloud computing

4. Select: how to select the optimal suite of applications and services to solve a business problem, how to target the best user groups and identify the best offerings to meet the business needs

5. Integrate: what it takes to put together all the different components and connect them with the legacy infrastructure; considers end-to-end design, connectivity, resilience and security.

6. Implement: how to make the design actually work, including technical migration and organisational changes

7. Operate: considers the day-to-day service management, administration, monitoring and support implications of cloud solutions

8. Control: tackles the core problems of compliance, risk and governance as they manifest themselves in cloud computing

9. Adapt: how to continuously refine a cloud-based solution in order to optimize it in a dynamic environment

10. Evolve: technological changes on the horizon for cloud computing and their potential effect on cloud services

The unique systematic book structure is very useful for all IT professionals architects and executives since it serves as a roadmap for embarking on a course in any new technology and is enriched with solid cloud-based guidance for every step of the way.

This book does a good job of breaking the cloud-computing problem into a manageable set of topics. CIOs or other enterprise-level strategic planners will find it a useful outline for guiding their work.

Rhoton is a professional management consultant and trainer, which has given him a good sense for presenting material in an orderly fashion.


Rhoton is a professional management consultant and trainer, so the book's hidden agenda is to convince the reader to engage Rhoton's services. (That's simply a fact of life for books written by professional consultants -- they make their money by selling services, not by selling books.) Consequently, the book isn't really very deep. Yes, there are lots of buzzwords and acronyms thrown around, but not enough real information to build a workable cloud-computing strategy. Mostly just enough to convince you that Rhoton knows what he's talking about.

Much of the book consists of information that Rhoton culled from publicly-available sources (mostly the Web and Wikipedia). Rhoton is very up-front about this, but it still makes the book feel artifically padded. Indeed, the final 130 pages are nothing but product descriptions taken from vendor websites and presented without commentary.

Rhoton claims that the book benefits from being a print-on-demand, self-published title. He says this allows him to keep the book up to date. And yet he makes serious errors when he presents technical details of vendors' offerings. -- mostly due to out-of-date information. For example, even though the current revision of the book was publsihed in 2010, Rhoton's description of Microsoft SQL Azure is based on an early, pre-release version of the product that had totally different characteristics. Basing an enterprise strategy on the details in Rhoton's book could lead to poor results.

Bottom line:

Rhoton does a good job of outlining the important topics that an enterprise planner needs to consider in order to move to the cloud. It provides a good check-list of topics that should be part of the planning process. In that sense, the book is rather like a set of training wheels on a bike. However, don't rely on this book for the details; it's not a reliable reference.

This books provides the most comprehensive picture of Cloud Computing that you will find in print today. The author covers all you need to know about Cloud Computing in ten very logically sequenced parts: Define, Assess, Design, Select, Integrate, Implement, Operate, Control, Adapt, Evolve.

Within these 10 parts, the author makes very practical and detailed explanations of areas related to Cloud Computing not typically found in other books, like management layers, ecosystem, infrastructure stack, platform as a service, how to assess benefits and challenges (strategic, risk and financial impacts), security architecture and design, employee changes, monitoring, governance and compliance, and even a list a Cloud Vendors.

With this book the author presents a document that is extremely practical and useful for consultants, architects, technologists, CIOs, CTO's, technology managers, and strategists who are actually involved with the planning and implementation of information technology - or for those who are just interested in Cloud Computing.

You would expect no less from someone who is known to have been one of the technology thought leaders at Hewlett-Packard for so many years - especially if you have read any of his other books. He has brought his considerable experience on Cloud Computing to bear here - and it shows when you see that what you learn from this book can put to immediate use.

The book is a must read if you work or plan to be in Information technology .

The only few chapters that a non-IT professional needs to read is the First, second and sixth Chapters . The description is geared towards a mass audience in a clear way that is easily understood. Any IT topic gets boring unless you build a storyline and examples. Story lines are missing,but examples (Amazon,Google) helps to retain Interest in the chapters.

It elaborates the known and subtle benefits of cloud ,while putting it from a historical to contemporary perspective not a rocket science,simple evolution). Unlike several books on computing , the book does not blindly recommend Cloud computing for the sake of it ex: A cloud-based solution that does not increase revenue or decrease cost is of little interest. And a non-cloud solution that improves the bottom line should be implemented regardless of the name you use to label it.)

Step into next level to know different types of clouds like private,public,partner,horizontal,vertical etc; what are these, which one fits you you will be surprised to notice that many of the IT in your firm is running in cloud for many years without ever mentioning the fancy word "Cloud computing"). Even a layman used cloud computing application a decade back. It was called Hotmail !

Once you get past the first Chapter, You need to have some IT background to get a grasp of the subject. Further review is geared towards the IT community. I am a software developer who come across the IT terminology's frequently and can relate to the author's description,understand the pains and fears of security, breach,integration,availability,scalability etc.

Forget Cloud Computing for a moment, I promise you will like this book if you are working in Information technology . There is something for everyone. If you are a programmer, you will know quiet a bit about security challenges (Heard of SAML?). If you are a hardware guy, you can learn about the cost implications of decisions made in IT and so on. If you are a director or a Vice President or a CIO, Do not feel ashamed, entire book is for you.

PS : I am reading the book on a Kindle cloud reader . Not as good as a Kindle on Ipad ,but certainly not bad.Try it out, will not be disappointed.

Cloud Computing Explained is one of the most compelling, yet easy to read implementation handbooks for enterprise-wide cloud solutioning. John Rhoton does more than just explain Cloud Computing, which is difficult to begin with, he goes beyond the hype and creates a "process" for implementing Cloud Computing. Starting with defining what "Cloud" really means to ending with the future evolution of Cloud Computing as well as upcoming Cloud Computing trends. Throughout the book, John Rhoton guides the reader through complex subject matter, simplifying multifaceted topics while giving enough information and detail to successfully begin the arduous task of implementing a "Cloud Computing Solution". As John Rhoton points out, his first and overriding objective is to provide a comprehensive, big picture of Cloud Computing. While on the surface, this may appear to be an easy task, but in reality is very difficult considering the varied definitions of Cloud Computing circulating throughout business. John Rhoton's secondary objective is to outline a "framework" for enterprises as organizations deal with the often confusing and many-sided realities of Cloud Computing. More than any book on Cloud Computing, Cloud Computing Explained goes beyond the hype and gets to the "core" of Cloud Computing, while describing the enormous benefits of implementing Cloud Computing for small and large organizations. Not to mention, when higher-ups asks about the "hottest technology trend" called Cloud Computing, you will have intelligent answers, which will no doubt benefit your career. Definitely a "must read" for those interested in Cloud Computing and anyone tasked with implementing Cloud Computing in their organizations.

John Rhoton's recent release "Cloud Computing - Explained" is by far one of the best books released this past year on the growing technology Cloud domain. Rhoton's years of real-world technology management and its implementation, in the field, with real clients, real implementation pressures, and, real resource-budget constraints, in an ever changing IT world, have all come perfectly together in an very resourceful, linear, thoughtfully written AND practical IT book. This isn't just another IT book on an IT fad - it's a much-needed implementation manual.

Rhoton's opening "Define" segment of the first 5 chapters are alone worth the price of the book where he "defines" What is a Cloud? a professional manner that is clear and to the point ...then diving into a concrete discussion of Cloud Architecture [better than I've seen or read elsewhere in published format], a much-needed essential first step with follow-on discussions on IaaS, PaaS, and, SaaS, getting to a very mature understanding as to how Cloud Computing is moving us to the next major paradigm shift of EaaS in the overall IT space. Rhoton then goes to discuss assessment, alignment, costing and design considerations, again, in a very mature linear manner, ending with solutioning, where selection of appropriate vendor solutions is well discussed. In addition, the Appendix on Cloud vendors is also worth reviewing as one of the better current catalogs of successful products/services in the field at this time.

This is a Cloud implementation text CIOs, CTOs, and, real Enterprise Architectures should read and can use as they learn and navigate through the major Cloud paradigm shift we all being impacted by today.

First a very comprehensive overview. All elements of a cloud computing life-cycle from idea to maintenance are covered in good detail including project considerations. I did learn everything I hoped to about current cloud services and a whole lot more.

the benefits of cloud environments and where they best apply. Each chapter provides the considerations and concerns when determining viability or architecture of cloud services.
The flavors of cloud services are discussed, SaaS (software as a service),PaaS, (platform) and IaaS (infrastructure) [read SPI like spy]. Strengths and weaknesses of clouds are discussed in good detail by each chapter. There is so much good content, the book can second as a reference if researching.

was critical of the number of vendors provided but those vendors are primarily limited to the last 1/5 of the book devoted to vendors and only referenced in the content where a unique or consequential service were provided by that vendor (architecture trends are important). Having the vendors and their offerings is one of the aspects of this book that provides completeness and reference others lack.

the content very smartly places security as an integral part of every cloud element and actually acted as a good refresher for many architectural security topics. An excellent presentation for laymen and supportive of generally accepted security methodologies.

A Vgood read, resource and cloud security mid level companion. Go for it.

I agree with the other reviews on this book! It's a terrific read! It provides a comprehensive, thorough explanation of cloud computing. I especially appreciated that the author manages to pull together the components of cloud computing into a complete picture.

The author's writing style also helps. It is straight-forward, clear and easy to follow - even when he addresses the more technical aspects of the cloud. The material is presented in a series of steps that can serve as a useful implementation guide as well as a reference. I really liked the way it is organized. My money and time were well spent on this one!

Cloud computing explained for those who want to gain and understanding of what it's all about. Cloud computing has a bit of a "cloudy" (pardon the pun...) future because there's a lot of insecurity associated with the concept. But it is being widely adopted at the moment because it permits more efficient use or today's high-powered computers.
