ABSTRACT
Businesses that use computing resources have learned to contend with a vast array of buzzwords. Some people think cloud computing is the next big thing in the world of information technology (IT). Globalization of computing assets may be the biggest contribution the cloud has made to date. Cloud computing may be viewed as a resource available as a service for virtual data centers. Managed service providers offer one of the oldest forms of cloud computing. Basically, a managed service is an application that is accessible to an organization’s IT infrastructure rather than to end users. Reliability is often enhanced in cloud computing environments because service providers utilize multiple redundant sites. Data centers, computers, and the entire associated infrastructure needed to support cloud computing are major consumers of energy. The chapter also presents an overview of the key concepts discussed in this book.
