A New Performance Assessment Modeling and Development of a Performance Assessment System for a Cloud Service

Cloud service is the next-generation core service in the field of green IT for maximizing the efficiency of IT resource operation and management, and energy consumption. Cloud service market size is expected to rapidly grow in the future due to easy usefulness, efficiency in operation and management, and relatively high industrial ripple effect by investment. Nevertheless, the market has not been considerably activated due to ICT users’ concerns on security and cost, loss of control, and uncertainty on reliability and performance when adopting and using cloud service. This study suggests a modeling for assessing the performance of cloud service and the performance assessment system based on the modeling in order to provide the standard for cloud service users to rely on and select cloud services which are suitable for their needs by providing objective and quantitative comparison and assessment results. In particular, this study defines the range for performance evaluation of the virtual machine (VM) targeting Infrastructure-as-a-Service among various cloud services, and deducts the items of performance assessment by analyzing requirements. The suggested system modulates and composes the target of performance assessment into five items of system performance, network performance, service performance, availability, and security performance. In addition, we aim to develop a system for performance assessment of VM based on those items, and to help use the system to manage the performance of cloud infrastructure services.
