Trust Evaluation Factors in Cloud Computing with Open Stack

Cloud computing can be used with three deploying models SAAS, IAAS, and PAAS. IAAS is the most adopted model used for research and innovations. On daily basis Tera bytes of data are being uploaded on the cloud. The Public cloud, Private cloud and hybrid clouds services are used by the people for hosting their applications and computations. One of the major obstacle used in selection of cloud service providers is the lack of trust on CSPs. CSPs are providing different levels of security according to the requirements of users. Proposed paper demonstrates the Trust evaluation, Trust calculation models, based on different security parameters like Turnaround time, Integrity, and reliability of data on cloud. How to select a cloud provider’s service, based on the derived parameters determines the trust value of service provider. A new dynamic trust calculation approach is proposed in this paper. Integrity, Turnaround time (TE) and reliability parameters are considered for trust evaluation. Comparative analysis of different cloud providers with real time calculations of different cloud machines are done and made a comparative analysis of the parameter, approximately 63% efficiency level is achieved while compiling the trust factor with standard cloud nodes. Open stack cloud software is used to create a cloud environment of the local machine which helps in compilation of the data at real time. Fog computing is used to calculate the results.
