The Concepts of Cloud Computing and their history

>> Introduction

The term "cloud" has spread very widely in the field of networks recently, and the term cloud appeared in the world of technology at the beginning of what is known as the Internet, where the Internet was likened to the cloud in transferring data from its primary site to its final sites in the cloud, and from here cloud computing took its concepts. As it is a term that refers to the computer resources and systems available in the networks, which in turn provide important and integrated cloud services without being restricted by local resources, in order to facilitate the process of use by scientists. (Montazerolghaem, Ahmadreza; Yaghmaee, Mohammad Hossein; Leon-Garcia, Alberto, 2020)

Cloud computing has emerged as one of the computing methods in which computing resources are presented as services that can be accessed by users via networks (the Internet) without the need to possess specific knowledge or skills. As services in addition to modern technical directives that are shared over the Internet to meet the needs of the user, and through this research paper we will learn about "concepts of cloud computing, and the history of origin and the related hypotheses".

>> The Concepts Cloud Computing:

There are many concepts that describe cloud computing, its mechanism of action, ways of responding with users, and the like. In general, the concept of cloud computing can be summarized in one definition, which is that “cloud computing is a technology based on transferring the processing and storage space of the computer to the so-called cloud, which in turn is a server device. Accessing it via the Internet, this means that IT programs are transformed from products to services, and the infrastructure of cloud computing depends on advanced data centers that provide large storage spaces for users and also provide some programs as services to users Web 2.0”. (Wang , 2012)

>> The Relationship Between Cloud Computing and Other Systems:

As a result of the close relationship between cloud computing, networks and the Internet, we find that it also has a close relationship with some other systems and software, and we find this relationship between both cloud computing and:

1.Automatic computing: which represents self-managed computer systems

2.Grid computing: It is a form of distributed computing and parallel computing

3.Major computers: They are computers with powerful specifications that link to computing

4.Server and client model: in importing user requests and providing services. (Buyya, Rajkumar, 2009) (Sun Microsystem, 2009)

>> History of Cloud Computing:

We previously mentioned that the emergence of the term cloud and its circulation in the technical field was related to the emergence of the Internet in its inception, and the term "cloud" was used to refer to the World Wide Web. As for the recent use of the term, it refers to computer network diagrams as an experimental picture of the infrastructure that they represent. Therefore, cloud computing was considered the term on the development of the virtual domain and virtual service architecture on the Internet and the extension of networks. (Danielson, Krissi, 2008)

Research indicates that the idea of cloud computing dates back to the sixties of the last century, as John McCarthy expressed the idea by saying, “You may organize computing to become a public service one day.” However, cloud computing applications did not have the opportunity to actually appear until the beginning In 2000, when Microsoft expanded the concept of using software through the web, many companies followed suit, and the most companies that played an important role in the field of cloud computing was Google, which launched many services that depend on this technology, but Google was not satisfied. By launching services to take advantage of this technology only, but in 2009 it launched an integrated operating system for computers that works through the concept of cloud computing. (B. Rochwerger, J. Caceres, R.S. Montero, D. Breitgand, E. Elmroth, A. Galis, E. Levy, I.M. Llorente, K. Nagin, Y. Wolfsthal, E. Elmroth, J. Caceres, M. Ben-Yehuda, W. Emmerich, F. Galan, 2009)

>> Conclusion:

The world has witnessed in recent times a great development in the field of computers, networks, and the field of communications in general. As a result, many systems have appeared and developed in these areas, which are concerned with serving users, and examples of these systems are what is known as statistical computing, whose concepts we have previously known, and although the emergence of this technology dates back to a relatively short period, it is noticeable that statistical computing has become one of the important technologies. For users, which allows the user to obtain and enjoy products in the form of services that are easily accessible to them.
