Ensuring Data Security in Cloud Computing: A VIKOR-Based Analysis

Cloud computing has transformed the IT industry by providing scalable and on-demand access to computing resources and redefining traditional infrastructure approaches. Its virtualized architecture offers flexibility, cost savings, and improved reliability. However, with increasing adoption, security concerns have intensified, making it necessary to address vulnerabilities in data protection, access control, and multi-tenancy. Research significance: This research is important as organizations increasingly adopt cloud-based technologies, and as they thoroughly examine cloud computing security. By addressing issues such as data security vulnerabilities, multi-tenancy challenges, and access control, the study provides valuable insights to secure cloud environments, ensure secure implementation, and support the advancement of this transformative technology. Methology: alternatives: Proximity to Users, Diversity of Services, Availability Zones (AZs), Cost and Performance Considerations, Regulatory Compliance. Evaluation criteria Distance from Consumer, Available Services, Performance Rating, Data Transfer Latency. Result: According to the results, Regulatory Compliance ranked highest, while Proximity to Users ranked lowest. Conclusion: According to the VIKOR method approach, regulatory compliance has the highest value for cloud computing security.
