||This concise book provides decision makers with the insight and practical tools they need to make intelligent decisions about cloud computing and manage an effective migration to this new paradigm. Cisco's Bill Williams explains why much of what businesses now know about information technology will change dramatically over the next five years, and helps executives anticipate and prepare for tomorrow's radically new environment. Williams briefly explains the storage, compute, and network platforms and technologies associated with the emergence of cloud computing, analyzes the cost curves involved, and links them to standard industry metrics. His up-to-date examples utilize return-on-investment (ROI) and net present value (NPV) to measure the impact of investing in owned/leased hardware vs. purchasing cloud-based resources. Software licensing, disaster recovery and high availability, and capacity planning examples highlight additional decision points, further illuminating the financial impact of cloud computing. The Economics of Cloud Computing walks through every step associated with a successful cloud transition, and outlines repeatable processes for predictable, consistent IT performance in cloud environments. Readers will find easy-to-understand tables and graphs, as well as a set of templates and guides for migrating to cloud services. These useful and up-to-date tools are also provided for download at a companion website.
