This book on Cloud Computing is the first I read with pleasure. The chapters all make sense to me, and the author is not shying away to give a solid technical foundation to what he describes and explains. The too frequent pitfall of Cloud Computing books is that they specify and describe in formal terms, and show adequate system-level schemes, but avoid technical details, and do not provide in-depth technical explanations, maybe because these call for a multi-disciplinary engineering background.
Dan Marinescu's book is clearly giving engineers deeper understanding for the rationale and parameters of the systems they have to use as a very opaque black box: Cloud systems, big data analytics. A 360 degree view of the subject is presented, not ommitting any of the key aspects, like security and privacy protection. Note that the policy references are mostly from the US. The EU initiatives on Cloud Computing such as the ETSI-led Cloud Standards Coordination and its report to the European Commission to be published in December 2013 may have to be included in the next releases of the book.
