The Economics of Cloud Computing
An Overview for Decision Makers
Bill Williams
Foreword by George Reese, author of Cloud Application Architectures
The decision-maker’s guide to cloud computing: from making the case to managing the transition
This concise book delivers the insight and tools you need to make intelligent decisions about cloud computing and effectively manage the transition to this new paradigm. Bill Williams explains how cloud computing platforms are transforming business IT and helps you fully understand the economies of scale and other benefits associated with “the cloud.”
Williams defines and explains cloud computing platforms and technologies, analyzes the costs associated with the IT supply chain, and (using industry standard metrics) creates a process for measuring the value of implementing cloud service models. He presents realistic and up-to-date ROI and NPV calculations comparing cloud strategies with conventional investments in owned/leased hardware. Through additional examples, he addresses costs and savings related to software licensing and disaster recovery/high availability, offering even deeper practical insight into the financial impact of cloud computing.
Writing for business leaders and “in-the-trenches” managers, Williams outlines the impact of cloud computing on the IT supply chain by contrasting legacy processes and systems with cloud computing implementations. To simplify deployment, Williams presents easy-to-use tables, a decision-maker checklist, and a comprehensive collection of additional resources for further study.
