Cloud Computing Definitions

Cloud Computing is defined in various ways. Following are the few definitions given by the authors in their articles. Based on the Cloud Computing definition provided by the National Institute of Standards and Technology (NIST) [1] and Information Technology Laboratory, David S. Linthicum [2] defines Cloud Computing as 

"Cloud Computing is a pay-per-use model for enabling available, convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction [1-2]." 

In the opinion of Barrie Sosinsky, "Cloud Computing refers to applications and services that run on a distributed network using virtualized and accessed by common Internet protocols and networking standards [3]."

Buyya et al. [4] defined the Cloud Computing as follows "Cloud is a parallel and distributed computing system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service level agreements (SLA) established through negotiations between the service provider and consumer."

For more definitions on cloud computing, provided by different authors, one can refer the book edited by Buyya et al. [5].
