This book describes warehouse-scale computers (WSCs) the computing platforms that power cloud
computing and all the great web services we use every day. It discusses how these new systems
treat the datacenter itself as one massive computer designed at warehouse scale with hardware
and software working in concert to deliver good levels of internet service performance. The
book details the architecture of WSCs and covers the main factors influencing their design
operation and cost structure and the characteristics of their software base. Each chapter
contains multiple real-world examples including detailed case studies and previously
unpublished details of the infrastructure used to power Google's online services. Targeted at
the architects and programmers of today's WSCs this book provides a great foundation for those
looking to innovate in this fascinating and important area but the material will also be
broadly interesting to those who just want to understandthe infrastructure powering the
internet. The third edition reflects four years of advancements since the previous edition and
nearly doubles the number of pictures and figures. New topics range from additional workloads
like video streaming machine learning and public cloud to specialized silicon accelerators
storage and network building blocks and a revised discussion of data center power and cooling
and uptime. Further discussions of emerging trends and opportunities ensure that this revised
edition will remain an essential resource for educators and professionals working on the next
generation of WSCs.
