The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.
Cloud computing emerge as a computational prototype as well as a sharing architecture and its main intention is to provide secure, quick, convenient data storage and net computing services and dispatched all …show more content…
From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.
2 Background of Cloud Computing
Professor John McCarthy, who was a computer scientist who instituted timesharing in late 1957 on modified IBM 704 and IBM 7090 computers, was the developer of Cloud computing. McCarthy around the 60s affirmed, "Computation may someday be organized as a public utility". McCarthy relayed on the support of some corporations who would help him to sell some computing resources through the utility of business model.
Thankfully, some different organizations purchased it for their use of computing resources (storage, processing, bulk printing, and software packages) available at service bureaus. Companies

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of
Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of
Cloud computing can be viewed as one of the most rapidly growing and evolving paradigm.Webmail,online storage and online documents are most famous examples in which customers can access their data via web browsers on the internet. The original idea of the cloud computing was delivered by J.C.R Licklider in sixties (Mohamed 2009). Cloud computing has developed since then and started to server the publics after internet offered a significant bandwidth in the nineties (Mohamed 2009). Cloud computing has been through many different phases and is still rapidly evolving.
Cloud computing provides various services to its users through internet using a pay as per usage plan giving users the freedom to use just exactly what they want and change their requirements accordingly based on their usage. Hence avoiding the huge costs that incur to setup and monitor a server system which has a limited scalability. Even though Cloud Service
We’ve all heard about this new phenomenon called cloud computing, but what exactly is cloud computing? Is it computation by a magic cloud instead of computers or humans? No, cloud computing is a popular term coined by the technology industry as storing, accessing, and computing data and programs over the internet instead of locally by your computer. Essentially, this so called cloud represents the Internet, and like real life clouds, it can’t be physically touched; rather, we know that it exists, it’s purpose, and it is quantifiable, but we can’t hold it in hands. Like weather clouds, cloud computing can be very powerful and a game changer that affect everyone. We will be discussing the impact of cloud computing, advantages and
Cloud Computing is picking up now a day’s though it was there in the industry and it is also considered a long-held dream of utility computing. Economies of scale
Since the innovation of the internet, people in computing fields have seek to find storage solutions that could provide users and organizations with capabilities to store and process their data distant from end-uses. Since 2000s, cloud computing has come into existence, later on, became business feasible through the observation that organizations start to substitute from self-owned hardware and software to subscription mode based models. Thus, we’re currently on the shift to cloud computing that may cause a dramatic growth in internet-based IT services in some industrial areas and some decline in other areas. By definition, cloud computing is an internet based computing for storing or sharing used computer or applications on multiple servers.
As with any new trend in the IT world, enterprises must figure out the benefits and risks of cloud computing and the best way to use this technology. The buzz around cloud computing has reached a fever pitch. Some believe it is a disruptive trend representing the next stage in the evolution of
“In recent 10 years, Internet has been developing very quickly. The cost of storage, the power consumed by computer and hardware is increasing. The storage space in data center can’t meet our needs and the system and service of original internet can’t solve above questions, so we need new solutions. At the same time, large enterprises have to study data source fully to support its business. The collection and analysis must be built on a new platform. Why we need Cloud Computing? It is to utilize the vacant resources of computer, increase the economic efficiency through improving utilization rate, and decrease the equipment energy consumption. Cloud Computing does not depend on special data center, but we can look it as the inevitable product of grid computing and efficiency computing. However, compared with general network service, Cloud Computing is easy to extend, and has a simple management style. Cloud is not only simply collecting the computer resource, but also provides a management mechanism and can provide services for millions of users simultaneously” .
The previous chapter demonstrated the key fundamentals of the research and an introduction to the concept of Cloud Computing. Even though a lot of research work has been done on the subject of cloud computing, the field is still a relatively new academic field. The National Institute of standards has established the standards related to Cloud computing and the research into the subject continues, especially with new tools and technology infrastructure that continues to evolve at a very fast pace.
This paper gives an overview at the structure and working of the idea of cloud computing.

In an attempt to discuss various security issues related to Cloud Computing, the authors have divided the article into nine areas as summarized below.
Cloud computing is currently being used by a large number of organizations. Many consider it a major development of the decade in computing. In this article I define cloud computing, various services available on the cloud infrastructure, then discuss the technological trends which have led to its emergence, its advantages and disadvantages, and the applications which are appropriate to outsource to a cloud computing service.
Data security has systematically been a major issue in IT. Data security becomes particularly serious in the cloud computing environment, because data are scattered in different machines and storage devices including servers, PCs, and various mobile devices such as wireless sensor networks and smart phones. Data security in the cloud computing is more complicated than data security in the traditional data systems.
Cloud computing is an internet based computing that depends on sharing computing with other resources rather than local servers or personal devices to handle applications. Cloud computing has fundamentally changed the way people view computing resources; rather than being an important capital consideration (Navavati, M., Colp, P., Aiello, B., & Warefield, A. (2014)). Cloud computing offers many potential benefits to organizations by making information technology (IT) services available as a commodity. IT services are services provided by IT service provider. Such services includes storing, retrieving, transmitting, and manipulating data for businesses or organizations.
