The cloud has been with us for a while but is still seen by many to be in ‘start up’ mode. This book not only reveals cloud to be well established, but also helps to anchor it by relating it to architecture as well as to service management, the two planks for balanced management of any technology.

The author asserts that it is the cloud that enables much of modern technology; from social networking, to big data, to Internet searches and even smartphones and their attendant apps.

The book is very good at defining everything as it goes along in very short clear statements, and the illustrations are both apt and clear. It contrasts and compares cloud to timesharing and shows in a very logical fashion that cloud is a natural evolution of what has been developing in IT over the last 40 or so years.

The author insists that for cloud to be deployed successfully both business and IT management needs to work together as never before. Part of the reason is that the cloud can either be ‘on premises’ or outsourced or a mixture of the two. And if it is not entirely ‘on premise’ then business management will need to be more involved and engaged than with traditional on-premise IT.

The author also demands that cloud and architecture are integrated, that a loose connection is not good enough. Similarly, he asserts that service management is no longer optional. In this respect he praises and recommends the implementation of ITIL.  

This book consists of five main parts preceded by a scene-setting introduction which clearly spells out its intent that: ‘(it) brings cloud computing and service management together with detailed recommendations for successful services built on cloud technology.’

The first part is really a detailed introduction and covers services, virtualisation, handhelds and clouds.

The remaining parts each respectively address:

  • Service management
  • Enterprise integration
  • Virtualisation
  • Clouds

Chapter 15: Conclusion is a very good summing up of the main points of the book:

  • Cloud practices
  • Strategy
  • ITIL design, transition and operations
  • Final summing up: service management is a cycle and not a single project; cloud implantation is a form of outsourcing made possible by high-bandwidth networks and virtualisation. Cloud implementation enables costs to be managed and more proportional with volume of work rather than as a high fixed cost.

In conclusion, this book is a valuable addition to the library of IT professionals considering or starting to engage in cloud implementation. Its main messages of integrating with architecture and deploying service management can be a useful tool in helping the IT professional in explaining why cloud implementation is not as simple as some cloud vendors would make it out to be.
