CLOUD COMPUTING: concepts and overview Ms. Sapna V. Ambadkar

Abstract

Abstract: Cloud Computing denotes the latest trend in application development for Internet services, relying on clouds of servers to handle tasks that used to be managed by individual machines. It is a relatively recent term, builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. With Cloud Computing, developers take important services, such as email, calendars, and word processing, and host them entirely online, powered by a vast array (or cloud) of interdependent commodity servers. Cloud Computing presents advantages for organizations seeking to centralize the management of software and data storage, with guarantees on reliability and security for their users. It implies a service oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, on-demand services and many other things. Cloud Computing presents advantages for organizations seeking to centralize the management of software and data storage, with guarantees on reliability and security for their users. This paper discusses the concept of Cloud computing, how it works, overview, applications, security and Cloud implementation available today
