Cloud Computing

Cloud computing is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of con gurable computing resources, which can be rapidly provisioned and released with minimal management e ort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers. It relies on sharing of resources to achieve coherence and economy of scale, similar to a utility over a network. This book establishes concrete, academic coverage with a focus on structure, clarity, and well-de ned building blocks for mainstream cloud computing platforms and solutions. Cloud computing has become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability, accessibility as well as availability. Cloud computing is the result of the evolution and adoption of existing technologies and paradigms.
