I was disappointed after reading the book. Not because the book was badly written or contained errors (except for two missing images). It was for what the book did not contain.
If you are looking for knowledge about how to move existing systems to the cloud and especially manager level information about costs, complexity, etc. this book is for you.
If you are looking for what the new cloud architecture can bring that was not possible before. You will be deeply disappointed. This book is like the first television shows: "One camera was used to film a teatre play". No lessons on how you should use distributed computational/data grids or messaging systems, alternative architecture ideas, etc. Cloud computing is more than putting a mysql cluster and jboss cluster on a rented farm of computers. No Google architecture techniques (Bigtable, map reduce), no Amazon behind the scenes tricks (Dynamo), no great ideas for new business models, etc. Just pure how do I move my existing web application to Amazon.
