Cloud Computing

Cloud is employed as associate degree abstraction of network/internet in system diagrams. Cloud computing is associate degree internet-centric manner of computing. Cloud computing refers to each the appliance delivered as services over the net and also the hardware and system within the datacenters that provide those services. “Cloud computing could be a model for facultative omnipresent, on-demand network access to a shared pool of configurable computing resources (eg. network , servers , storage , applications , and services ) that may be speedily provisioned and discharged with minimal management effort or service supplier interaction.”

Define by Buyya [utility-oriented nature].

“A cloud could be a kind of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and conferred together or a lot of unified computing resources supported service-level agreements established through negotiation between the service supplier and consumers.”

Cloud Computing

It permits dealings infrastructure , runtime atmosphere ,and services on a pay-per-use basis. It is a good composition of many technologies

Web 2.0

Web-based access to any or all the functions that ar commonly found in desktop applications.

Service Orientation Computing

brings interactivity and suppleness into sites. Service as a main building blocks of application and system development.

Virtualization

Abstraction of a number of the elemental components for computing such as h/w, storage etc. Cloud computing VisionDefine Cloud. Cloud is employed as associate degree abstraction of network/internet in system diagrams. Cloud computing is associate degree internet-centric manner of computing. Internet is represent either the medium or the platform through that cloud computing services are delivered and created accessble. - define by Armbrust Cloud computing refers to each the appliance delivered as services over the net and also the hardware and system within the datacenters that provide those services. -Define by U.S National Institute of ordinary and Technology (NIST) “Cloud computing could be a model for facultative omnipresent, on-demand network access to a shared pool of configurable computing resources (eg. network , servers , storage , applications , and services ) that may be speedily provisioned and discharged with minimal management effort or service supplier interaction.” - Define by Buyya [utility-oriented nature] “A cloud could be a kind of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and conferred together or a lot of unified computing resources supported service-level agreements established through negotiation between the service supplier and consumers.”
