Cloud Computing Concept, Technology and Architecture

Abstract

Cloud computing has materialized as a new platform in the field of Computer Science. It is Internet-based computing, where in hardware and software resources are provided to user’s on-demand. Cloud computing provides a platform with an enhanced and efficient way to store data in the cloud server with different range of capabilities and applications. Different cloud computing models allow access to information and computer resources from anywhere a network connection is available. Cloud services include online file storage, social networking sites, webmail and online business applications. It provides a shared pool of configurable computing resources, including data storage space, networks, computer processing power and specialized corporate and user applications with minimal management effort or service provider interaction. This research paper presents what cloud computing is, share some information regarding the different aspects of cloud computing, the various cloud models and the overview of the cloud computing architecture. We also discuss cloud computing features and security issue, cloud computing challenges and the future of cloud computing.
