Abstract:
Cloud computing is setting off great changes in the IT industry. There are more and more researches on cloud computing. And this paper focuses on cloud computing too. At the beginning this paper describes the characteristics and definitions of cloud computing, and then introduced its services patterns (including SaaS, PaaS and IaaS) and deployment patterns(including public cloud, private cloud and hybrid cloud), at the end lists the cloud security challenges that cloud computing faces.Cloud computing, now-a-days has become the jargon in the industry of IT. It is a model that gives worldwide access to shared pools of configurable resources over the internet. That means it run several applications or programs at the same time on more than one computer. The nature and usage of the cloud computing are developing rapidly both virtually and in reality. It is making things easier for the user of internet by many of its attractive features but these features, have not just only challenged the existing security system, but have also revealed new security issues. In this paper the deployment of cloud models are discussed . The cloud models are deployed as public cloud, private cloud and hybrid cloud. Each of these models have their own advantages and disadvantages. Cloud also provides some services like software as a service (SaaS), Platform as a service (PaaS), Infrastructure as a service (IaaS) . This paper is an insightful analysis of the features as well as the securities challenges of Software as a Service (SaaS) for cloud computing.

Cloud computing is a recently developed computing model which comes from distributed computing, grid computing, virtualization technology, and many more computer technologies. Cloud computing is a technique to increase the capacity and add ability dynamically without spending on new infrastructure or licensing new software. The security issues of cloud computing and the techniques to overcome the issue have been discussed in this paper. The security issue of cloud computing is a significant problem and it can hamper the fast development of cloud computing. The basic security problem in cloud computing is service availability and data privacy. A single security technique cannot resolve the security problem of cloud computing, various traditional new strategies and technologies need to utilize together to protect the total cloud computing system.

Distributed Computing is a form of computing in which a group of independent systems are connected to a computer network. Cloud Computing is one of the emerging domain in the field of Computer Science. With the help of cloud computing, the computing services can be delivered over the internet. Before the advent of cloud computing, the business applications were found to be complicated, expensive and the software and hardware requirements of these applications were daunting. These issues were resolved in cloud computing since the hardware and software are maintained by the cloud vendors. Another advantage of using cloud computing is that it follows pay-per-use technology which means that the user only pays for the resources he/ she consumes. The main goal of the security principles in cloud computing is to ensure that the Confidentiality, Integrity, and Availability of the data are preserved. This paper presents an extensive survey of the security threats; its countermeasures and testing that are available in cloud computing.

Cloud computing is a new technology, which is the fusion of computer technology and Internet development. It will lead the revolution of IT and information field. However, in cloud computing data and application software is stored at large data centers, and the management of data and service is not completely trustable, resulting in safety problems, which is the difficult point to improve the quality of cloud service. This paper briefly introduces the concept of cloud computing. Considering the characteristics of cloud computing, it constructs the security architecture of cloud computing. At the same time, with an eye toward the security threats cloud computing faces, several corresponding strategies are provided from the aspect of cloud computing users and service providers.

This paper is about the An Analytical Study on Cloud Computing. Cloud computing is the development of parallel computing, grid computing, distributed computing, and virtualization technologies which define the shape of a new area. In contrast to a variety of benefits related with cloud computing, there are certain challenges as well. These challenges include security, privacy and reliability of data, high costs of data transfers, and regularity in the availability of services, and bugs in large-scale distributed systems. Cloud computing is a method of computing in a place that provides users with the ability of information technology as a service and allows them to have access to these services on the Internet without having limited information. Cloud computing can help businesses transform their closing server infrastructures into dynamic environments, expanding and reducing server capacity depending on their demand. Cloud is a image to describe web as a space where computing has been pre-installed and close as a service; data, operating systems, applications, storage and processing power close on the web ready to be shared. In cloud computing data owners expand their complex data management systems from community sites to the public cloud for great pliability and cost-effective. The searching of this study that highlight there are five main issues related with cloud computing execution which are Mobility and Cloud Government Application security issues, Cloud Security data, cloud security platform, Cloud Security Services and Application, cloud network security issues and infrastructure issues.

The cloud computing is a new computing model which comes from grid computing, distributed computing, parallel computing, virtualization technology, utility computing and other computer technologies and it has more advantage characters such as large scale computation and data storage, virtualization, high expansibility, high reliability and low price service. The security problem of cloud computing is very important and it can prevent the rapid development of cloud computing. This paper introduces some cloud computing systems and analyzes cloud computing security problem and its strategy according to the cloud computing concepts and characters. The data privacy and service availability in cloud computing are the key security problem. Single security method cannot solve the cloud computing security problem and many traditional and new technologies and strategies must be used together for protecting the total cloud computing system.
