Cloud computing between theory and practice

Abstract

The aim of the study was the building up of a knowledge matrix in which there is an explanation of the features of cloud computing, its concept, rise, characteristics, benefits and the possibility of its application in education. Studies have agreed that cloud computing is a group of related technical services which are centrally managed via local informational communication network or the internet through what is called the cloud, in a way that changes information technology programs from products to various computing services for clients.
This aims at shortening time and place, speed of accomplishment and the exploitation the potential and capabilities of the service provider in order to provide great storage spaces for users and the achievement of the biggest investment return for data centers without the needs for purchasing highly costing devices. Cloud computing represents the new technological trend for coming generations, especially in the field of education. This computing is considered the basic environment and platform for the future of electronic future.
The idea of cloud computing dates back to the sixties of the past century. John McCarthy pointed out to (the possibility of organizing computing to become common one day), but this idea did not come to real practice until the beginnings of the third millennium by technology companies such as Apple, HP and IBM which have come to compete with Microsoft, followed by Amazon web services. Then came Google cloud applications, followed by open Nebula programs, followed by (I cloud) of APPLE company. This has had its great effect on the support and development of the various electronic cloud services in order to offer services in all fields, especially education. They provide beneficial flexibility for individuals groups, committees, institutions and companies. However, there have been some disadvantages of this new product as it affects the environment, security fears, privacy of information, documentation, authorization and protection of intellectual right, The study concluded the emphasis that cloud computing is the future and the world is heading, toward it if technically administrative and financial challenges are eliminated which encounter the application of cloud computing services.
