Book Review: To the Cloud: Powering An Enterprise

To The Cloud: Powering An Enterprise introduces the concepts of cloud computing from a high-level and strategic standpoint. I’ve read quite a few tomes on cloud computing and I was interested to see how this one would stack up against the others.

The book is not too weighty in technical language so as not to be overwhelming and intimidating. However at ninety five pages, one might argue it is a bit sparse for a $30 book, if you purchase it at full price.

It is organized nicely around initiatives to get you moving with the cloud.

Chapter 1, Explore takes you through the process of understanding what the cloud is and what it has to offer.

Chapter 2, Envision puts you in the drivers seat, looking at the opportunities the cloud can offer in terms of solutions to current business problems.

Chapter 3, Enable discusses specifics of getting there, such as selecting a vendor or provider, training your team, and establishing new processes in your organization.

Finally in Chapter 4, we hit on real details of adopting the cloud in your organization. Will you move applications wholesale, or will you adopt a hybrid model? How will you redesign your applications to take care of automated scaling? What new security practices and processes will you put in place. The authors offer practical answers to these questions. At the end there is also an epilogue discussing emerging market opportunities for cloud computing, such as those in India.

One of the problems I had with the book is that although it doesn’t really position itself as a Microsoft Cloud book per se, that is really what the book aims at.

For example, Microsoft Azure is sort of the default platform throughout the book, whereas in reality most folks think of Amazon Web Services to be the sort of default when talking about cloud computing. Although specifically, Azure is really a platform, while AWS is Infrastructure or raw iron, that can run Linux based Operating Systems, or Windows Azure stuff.

Of course having a trio of Microsoft executives as authors gives a strong hint to readers to expect some plugging but a rewrite of the title would probably manage readers’ expectations better.

The other missing piece with this book is a chapter on tackling new challenges in the cloud. Cloud Computing – Azure or otherwise, brings challenges with respect to hardware as using the cloud means deploying across shared resources. For example it’s hard to deploy a high-performance RAID array or SAN solution devoted to one server in the cloud. This is a challenge on AWS as well, and continues to be a major adoption hurdle. It’s part of the commoditization puzzle, but it’s as yet not completely solved. Such a chapter to discuss mitigating against virtual server failures, using redundancy, and cloud components to increase availability would be useful.

Lastly, I found it a bit disconcerting that all of the testimonials were from fellow CTOs and CIOs of big firms, not independents or other industry experts. For example I would have liked to see George Reese of Enstratus, Thorsten von Eicken from Rightscale or John Engates from Rackspace provide a comment or two on the book.

Overall the book is a decent primer if you’re looking for some guidance on Microsoft Azure Cloud. It is not a comprehensive introduction to cloud computing and you’d definitely need other resources to get the full picture. At such a hefty sticker price, my advice is to pick this one up at the bargain bin.
