Cloud computing is tend which is integrity to web 2.0. Number of prominent providers as Amazon, Google, Sun, IBM, and Oracle have also extended their computing infrastructures and platforms to provide top-level services for computation, storage, and databases. As the sensitive applications and data are moved into the cloud data centers, run on virtual computing resources in the form of virtual machine. The authors have, therefore, proposed an effective with better performance. The idea of handing over important data to another company is worrisome; such that the consumers need to be vigilant in understanding the risks of data breaches in this new environment. In this paper, we aim to pinpoint the challenges and issues of cloud computing. Information deduplication is a strategy for taking out copy duplicates of information, and has been broadly utilized as a part of distributed storage to diminish storage room and transfer data transfer capacity. However, little is known about the factors most likely to be associated to the adoption behavior of cloud computing services among small and medium enterprises operating in Lebanon. Despite many benefits of cloud computing, the organizations are slow in accepting cloud computing service model because of security concerns and challenges associated with management of this technology. activities. Cloud computing is a new computational paradigm Abstract: Fog computing paradigm extends the storage, networking, and computing facilities of the cloud computing toward the edge of the networks while offloading the cloud data centers and reducing service latency to the end users. As the huge usage of Internet users in the world, cloud must be a vital area to think on more. The analysis shows that context-specific factors (i.e. We can achieve an accurate understanding of the security issue "delta" that cloud computing really adds by analyzing how cloud computing influences each risk factor.

Computing services offered by cloud computing include social networking and interpersonal computing, however, the main focus is on online software applications, data storage and processing power [3]. Even if developers are in control of the security, they do not have the assurance that the development environment tools provided by a PaaS provider are secure.Cloning and Resource PoolingCloning means with replicating or duplicating the data.. Cloning can lead to data leakage problems which reveal the machine's authenticity. This paper provides the security challenges of service and deployment models. In this paper, we aim to pinpoint the challenges and issues of Cloud computing. Security is one of the most significant issues, which prevent the development of cloud, easily. The cloud computing uses the internet as the communication media. Here, the authors define four indicators of cloud-specific vulnerabilities, introduce a security-specific cloud reference architecture, and provide examples of cloud-specific vulnerabilities for each architectural component. Despite the potential gains Hence, while cloud computing provides the convenience of sharing resources and compute capabilities for individuals and business owners equally, it brings its own challenges in maintaining data privacy [PH10]. In this paper, we have discussed the security issues, the challenges and the opportunities in the adoption and management of cloud computing services model in an organization. major issues with regard to authenticating users’ critical data. First, as is true for many discussions about risk, basic vocabulary such as "risk," "threat," and "vulnerability" are often used as if they were interchangeable, without regard to their respective definitions.
