Abstract
En 中文
The rapid advances in cloud computing have led to an marked increase in the number of service providers, making it challenging for users to select the most appropriate vendor for their needs. Many service users prioritise trust and security when selecting the ideal service provider and ignore other equally important considerations, such as Quality of Service (QoS) and energy efficiency. This study introduces a cloud service selection and recommendation (CS-SR) using a Trust Computation Framework (TCF) and a lightweight blockchain mechanism that combines qualitative and quantitative QoS attributes. The lightweight lightweight blockchain in the proposed system addresses the privacy, security, scalability, and authentication challenges commonly encountered in many cloud platforms. Experimental comparison with existing selection processes the proposed technique achieves superior performance based on energy efficiency and execution time. It provides a effective solution that considers trust, security and user needs that lead to better cloud service selection.
