      The preface states that this book is intended to prepare your Web
      applications to succeed in the cloud, although it hasn't said what the
      cloud is, nor is the example used particularly clear about what goes,
      or went, on.

      Chapter one attempts to define cloud computing, but does so in a
      highly promotional, and not particularly useful, manner. If you can
      use any browser, any operating system, and any Internet access
      provider to use a service, that's cloud computing. (Does this mean my
      local library's online catalogue is a cloud?) Later the material also
      mentions pay-as-you-go services, as well as distributed storage and
      processing. A large section provides an overview of the AWS (Amazon
      Web Services) system. More detail on AWS is given in chapter two,
      although the explanations are not very clear. (This may be in part
      because Reese does not fully understand some of them: his outline of
      the use of public/private key pairs makes no sense unless Amazon
      intends to allow a serious attack on the operations controlled by its
      accounts.) (It's fairly clear that this book was rushed to market in
      order to take advantage of the current interest in cloud computing: so
      fast that they forgot a number of the illustrative figures.) Chapter
      three provides some guidance in regard to calculating costs and
      reliability: the examples are from AWS, but the formulae and process
      are the same as for any information system. The advice on preparing
      your application for a scalable and distributed environment, in
      chapter four, is confusing. A wide range of technologies are
      addressed, and there is so much hedging and backtracking that it is
      very difficult to determine which suggestion the author actually
      wishes to stress, in the end. In terms of security, chapter five
      suggests you encrypt your data, harden your applications, and then
      describes some aspects of Amazon's operations. Disaster recovery
      appears to some to be inherent in cloud computing, but chapter six
      notes that you still have to do all the same disaster planning work,
      with the proviso that some things you want to do AWS won't let you.
      Chapter seven says you can buy more cloud as you need it.

      This book provides relatively little in terms of architectural
      guidance. It does promote AWS at every turn, and describes some of
      the functions and API (Application Programming Interface) calls for
      that system.

      For the time will come when men will not put up with sound
      doctrine. Instead, to suit their own desires, they will gather
      around them a great number of teachers to say what their itching
      ears want to hear. - II Timothy 4:3
