Cloud Privacy: Service-Centred Model Perspectives

These days, cloud computing is becoming more and more popular due to its excellent and affordable services. The quality of its products and services has made it unavoidable for cloud services to become more integrated into people's and organizations' everyday lives during the last ten years. Pay-per-use features, which are easily accessed on demand, force businesses to outsource some of their processes, increasing service quality and speed. Starting in 2019, the latest market trend points to a flourishing trajectory in the direction of cloud settings in the next years. Even with all of the advantages that cloud computing provides to businesses and consumers, security issues are expected to remain the main obstacle facing the cloud in 2020. Security is affected by a number of variables. Cloud computing technologies like virtualization and multitenancy, when combined with on-demand functionality, provide new avenues for criminal activity to exploit weaknesses. Using a survey on security issues in service-based internet computing, this study aims to determine the present status of the sector. This paper's main contribution is an analysis of the previous ten years' trends in cloud security and the provision of a thorough taxonomy of security flaws across the three layers of the model: infrastructure as an service ( IaaS as a service (PaaS), and software as a services (SaaS).
