The contents demonstrate the state of the art in big data enabled data centers. The book is very well written and edited for generic clouds, so specialized technologies like OpenGL/OpenCL GPUs are not covered. Common performance and scaling concerns are addressed. Vertical business concerns are not mentioned.
My assessment is that this is a marketing tool for CIO/CTO/Program Manager personnel, a self study tool for architects and engineers, and a gentle introduction for project staff who are new to big data.
