K.V. K Mahesh Kumar

Abstract: This Research paper explores cloud computing architecture, service delivery models, Security & Privacy Issues and Trust Challenges. Evaluates all three service delivery models Software-as-a-Service (Saas), Platform-as-a-Service (PaaS) and Infrastructure-as-aservice (IaaS) and their deployment, requirements and services they provide. In the next section Security & Privacy Issues has been discussed and focus is on potential reasons for them to cause. Also discusses the lack of common cloud security standards with constructive discussion on public cloud providers and on their proprietary security standards. Overview on Challenges with Trust between Cloud provider and cloud user and suggests solutions for inculcating trust among cloud provider and cloud user with the help of trusted thrid party. Solutions and recommendations are suggested to safeguard user Data in the cloud by implementing Data security measures such as use of Crypotography and Trusted platform module (TPM), Data integrity etc. This research paper also focuses on future scope of cloud computing and its evolution in the field of outsourcing and urges on the need of global security standards for mitigating security issues, privacy threats and Trust challenges for wide acceptance of cloud computing in organizations.
