A REVIEW ON CLOUD COMPUTING ENVIRONMENT

ABSTRACT In computer’s world these days cloud computing plays very important role. It gives user facilities like group of things such as software, platform and infrastructure services. Virtualization is the backbone of cloud resource sharing. Security is also a main problem of cloud. Multiple users have their own perception related to the cloud. By making use of cloud computing techniques the user is easily able to use to resources anywhere by using internet. So this technique is very useful in user’s daily life. One of the factors for cloud computing is cloud services which were provided by the cloud (IAAS, PAAS, and SAAS). These services enable users to access infrastructure, platform and software. Even resources are allocated to users according to their requirements. But many people think that using cloud resources and its services is not safe because there is no guarantee of information which is controlled or maintained by the vendors. There are some security issues which are usually experienced while using the techniques of cloud computing. The present research presents an overall investigation data security, protection and issues in the cloud. The paper also defines the literature review related to the cloud computing issues and treats. Various security concerns are also discussed in this paper.
