 Major enterprises and small start-ups are beginning to embrace cloud computing for the scalability and reliability that cloud vendors can provide. This book demonstrates how to implement robust and highly scalable cloud computing applications. Filled with comparative charts and decision trees to help navigate the many implementation alternatives, the author describes the major available commercial offerings and guides readers in choosing the best combination of platform, tools, and services for a small, growing start-up or an established enterprise. Aimed at software developers and their managers, the text details cloud development environments, lifecycles, and project management.Table of ContentsAbout the Author Dedication Author's Acknowledgements How to Read This Book Preface  Executive Summary 1 Cloud Computing is a True Paradigm Shift            2 From Do It Yourself to Public Cloud - A Continuum 3 Cloud Computing - Is It Old Mainframe Bess in a New Dress? 4 Moving Into and Around the Clouds and Efforts at Standardization 5 Cloud Economics and Capacity Management 6 Demystifiying the Cloud: A Case Study Using Amazon's Cloud Services (AWS) 7 Virtualization: Open Source and VMware 8 Securing the Cloud - Reliability, Availability and Security 9 Scale and Reuse- Standing on the Shoulders of Giants 10 Windows Azure           11 Google in the Cloud 12 Enterprise Cloud Vendors 13 Cloud Service Providers            14 Practice Fusion: A Case Study 15 Support and Reference MaterialsIndex

 Cloud computing has recently emerged as a subject of substantial industrial and academic interest, though its meaning and scope is hotly debated. For some researchers, clouds are a natural evolution towards the full commercialisation of grid systems, while others dismiss the term as a mere re-branding of existing pay-per-use technologies. From either perspective, "cloud" is now the label of choice for accountable pay-per-use access to third party applications and computational resources on a massive scale. Clouds support patterns of less predictable resource use for applications and services across the IT spectrum, from online office applications to high-throughput transactional services and high-performance computations involving substantial quantities of processing cycles and storage. The concept of clouds seems to blur the distinctions between a variety of technologies that encompass grid services, web services and data centres, and leads to considerations of lowered-cost provisioning for bursty applications.

This book provides comprehensive coverage of the state of the art in cloud computing, highlighting and clarifying the conceptual and systemic links with other distributed computing approaches.

 The latest jargon in the digital world, "cloud computing" leaves many small-business owners scratching their heads.  At its simplest, cloud computing enables businesses to do away with servers and much of their other IT hardware by running their software online.  Web-based email programs like Yahoo or Hotmail are examples of cloud-based applications; Microsoft is making its entire Office suite available free in the cloud; Google and others also have productivity suites in the cloud.
Dr. Williams eschews the jargon and marketing hype generated by IT vendors and helps business owners think clearly about how cloud computing could help improve their business.  He addresses fears related to data security and business continuity and also examines how cloud computing can impact a business's carbon footprint.  Case studies explain how businesses such as Dell and The New York Times have used cloud computing to their advantage.
