|A Cloud is a type of parallel and distributed system consisting of a collection of interconnected and virtualised computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers [R. Buyya et. al, 2009].|
|Cloud computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage, applications,
and services) that can be rapidly provisioned and released with minimal
management effort or service provider interaction. The cloud model is
composed of five essential characteristics (On-demand self-service,
broad network access, resource pooling, rapid elasticity, measured
service), three service models (Software as a
Service (SaaS), Platform as a
Service (PaaS), Infrastructure as a Service
(IaaS)), and four deployment models (public cloud, private cloud,
community cloud, and hybrid cloud). [NIST, 2011]
Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is called a Cloud.[M. Armbrust et al., 2009]
Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the Internet) [Wikipedia].
