I. Introduction

Cloud computing is set of resources that are being allocated on demand. Cloud computing proposes new ways to provide services. These new innovative, technical and pricing opportunities bring changes in the way business operated. Cloud computing is the matchless computing technology. Cloud computing is a new label to an old idea. Cloud computing is a collection of resources and serviced provided by cloud service provider through internet. Cloud services are distributed from data canters sited all over the world. Cloud computing makes possible for its users to use the virtual resources via internet as per requirements. Cloud computing grabbed the spotlight in few years. General example of cloud services are Google Engine, Oracle Cloud, Office 365. As the cloud computing is growing rapidly this also leads to severe security concerns. Lack of security is the only barrier in wide adoption of cloud computing. The rapid growth of cloud computing has brought many security challenges for users and providers.

II. Cloud Service Models Cloud Software-as-a-Service:

Software –as-a-Service is a software distribution scheme which gives right to access the software and its functions remotely as a web-based service. Software-as-a-Service permits organizations to get into business functionality a very low cost normally less than paying for licensed applications in view of the fact that SaaS charges are built on a monthly fee. As so the software is hosted remotely users do not require to pay for additional hardware. Software-as-a-Service eliminates the all possibilities for organizations to handle the installation, set-up, daily preservation and maintenance. Cloud Platform-as-aService: the capability provided to the users to deploy onto the cloud infrastructure. PaaS model, cloud suppliers brings a computing platform, naturally comprising Operating System, Programming Language execution environment, database and wed servers. Application developers can develop and run their software results on cloud platform with no cost and difficulty of acquiring and handling of the main hardware and software films, for examples Oracle cloud platform-as-a-service, Oracle provides the Database as platform. And other example is windows azure. In other means Platform-as-a-Service is the facility to offer to the users to deploy user-designed or obtained applications on the cloud infrastructure. PaaS can largely be characterized as application development environments proposed as a „Service via the cloud supplier. Users uses these platforms which is being normally have Integrated Development Environment (IDE), so as it comprises the editor, compiler, build/execute and deploy features to develop their applications. And users deploy their applications on the infrastructure provided by the cloud supplier. Cloud Infrastructure-as-a-Service: The cloud infrastructure such as hardware, servers, routers, storage, and other networking modules all are granted by the IaaS supplier. The end user takes on these offered services based on their requirements and pay for what they have used. The end user is capable of deploy and run any software, which comprise Operation Systems, applications. The end user does not supervise or monitor the core cloud infrastructure, but has hold over the operation systems and deployed application. At this juncture the end user needs to experience the resource requirements for the precise application to make use of IaaS properly. Flexibility and scaling are the liabilities of the end user, not the supplier. Moreover IaaS is small task performing it-yourself information hub so as you would require to form the means (server, storage) and make the task completed. Waiting right away, small end users did not have the investment to make a purchase of immense computing resources and to make sure that they had the space they wanted to manage unpredicted spikes during load. Amazon Elastic Compute Cloud (Amazon EC2) is an infrastructure –as-a-Service model that facilitates scalable compute volume, on demand, in the cloud. It actually allows end users to leverage Amazons huge infrastructure with no up-front investments. Amazon EC2 decreases the clock needed to get hold of and boot latest server instances and permit users to immediately scale space – equally up and down as their computing needs vary.

III. Cloud Deployment Models :

Public Cloud-A cloud is to be entitled as public cloud when the services (like applications, storage) are being provided over network that are available publically, anyone can access it.Private Cloud – A private cloud is an infrastructure that provides the services to a single organization, whether managed by internally or by a third party. Cloud which is hosted externally is termed as “externally hosted” private cloud and other hosted by third party are termed as “on premise” private cloud. Community Cloud-It comprises sharing of computing infrastructure between organizations of identical community. Hybrid Cloud-A hybrid cloud is a collection of private as well as public cloud options.) That remains unique entities but is bound together by standardized or proprietary technology.

V Conclusion

Cloud computing is the cost, time and performance effective technology. Of course the usage of cloud computing will surely will increase more in next few years. In this paper we have discussed and surveyed basic of cloud computing and security issues in the cloud computing. Some security issues are the key concern in the cloud computing. Especially privacy and integrity of data are the key concern security issues. In the cloud as data is stored publically and we really dont know where the data is being stored, we dont know the exact location of the data, due to this data stored in the cloud has a higher risk of being accessed by un- theorized person during storage as well as transmission.
