A trust is a social problem and trust management is a be prominent among the most demanding issue for the tackling and development of cloud computing. The management of cloud environment is highly dependent on the trust relationship between the cloud service providers and their customers (and/or other businesses). This trust is not only dependent on the latest technological tools, but rather also dependent on the management strategy in such highly critical environment. To achieve this objective, a survey was conducted related to the acceptability of the cloud services which has resulted in three main sections. These were: security, data protection and ethics in cloud computing environment. In this article, we elaborate the design as well as implementation of Cloud Armor, a reputation-predicated trust management system which provides an arrangement of functionalities to distribute Trust as a Accommodation (TaaS), including i) a novel convention to demonstrate the credibility of trust inputs as well as preserve clients’ security, ii) Not only a miscellaneous but additionally robust credibility model for quantifying the credibility of trust feedbacks to keep cloud accommodations from malignant clients and to analyze the dependability of cloud accommodations, and iii) an availability model to deal with the accessibility of the decentralized utilization of the trust management accommodation. The achievability and advantages of our methodology have been endeavoured by a model and test studies utilizing an amassment of true trust feedbacks on cloud accommodations
