Cloud computing is a type of computing model in which resources are accessed from a centralized pool of resource. The cloud management software has to manage the resources at large scale. The cloud represents ubiquitous computing means that it found everywhere. Cloud computing has become an alternative means of internet for this computing world. Cloud user and the cloud service provider are the two main units involved in cloud computing. Since a cloud is the set of many nodes, which can support a variety of applications which is used by the clients on the basis of pay per use. In this survey paper, we introduce in depth analysis of security issues in the cloud computing environment and challenges which focus on the types of cloud computing. We show cloud trust protocol, which is a solution approach to limit these challenges and issues.
