Cloud Computing

Abstract

The cloud computing concept known also under the terms of cloud services, cloud computing, cloud computing or cloud concepts of English Cloud computing is a paradigm that can offer services computer through Internet. The services related to the computer system are provided over the internet and are arranged in the form of a cloud. Hence, the name cloud computing. According to the IEEE Computer Society, is a paradigm in which information is stored permanently on Internet servers and is sent to cache temporary client, which includes desktops, entertainment centers, laptops, etc. the paper discusses in detail the concept of cloud computing as well as its types and rationale for employability.

Introduction

In the past few years there has been an explosive growth in computer usage for business, government and educational purposes. At the same time, the global nature of the Internet has opened up global markets and global competition. The combination of increased computer usage, global collaboration, and competition has brought with it the accompanying need to maximize the use of available resources while minimizing costs. One area of growing interest for meeting these needs is the use of cloud computing to centralize computing and information management functions for large, often geographically dispersed organizations and individual people (Wu & Lederer, 2009, p. 419).

In late 2006, Google CEO Eric Schmidt publicized the cloud computing concept. As discovered during the literature search, an extensive increase in cloud computing research has occurred, especially starting around 2008. Research efforts emphasize a variety of topics related to cloud computing. Some of these topics include applications and their capabilities, costs, the need for cloud computing, security, reasons for adoption, and growth trends. The focus here is on factors influencing the adoption of cloud computing as a method for performing computing and information management functions for an organization.

Background of the Study

These technologies such as grid computing, utility computing and thin client, as described by Leavitt (2009) are described as follows. A thin client is a keyboard and monitor connected to a centralized computer. Grid computing is an arrangement in which multiple similar systems, often geographically separated, can process computing jobs dispatched from a user to a centralized server. This centralized server dispatches the computing jobs to available computing resources. Utility computing is a method of providing computing to remote users, often on a fee basis, based on cycles used, much as providing an electrical utility. Both grids computing and utility computing have many features similar to those of cloud computing, with users sending jobs to a central server that arranges for these jobs to be run (Wang, Archer & Zheng, 2006, p. 337).

Leavitt also includes a general group called services, though NIST spreads these services applications over the other three ...
