A SLA-based scheduling approach for multi-tenant cloud simulation

Abstract

Modern product development becomes increasingly collaborative and parallel, which raises the need for sharing simulation resources in a multi-tenant simulation environment. However, the service requests and scheduling policies of tenants differ since system resources are shared by tenants. In order to deal with this issue, the framework of monitoring, detecting and scheduling system performance isproposed. As SLA is produced as the contract for negotiations between tenants and the service provider, the WS-Agreement specification is applied and improved to represent the service contents and qualities. Based on the SLA template, a dynamic resource distributing mechanism is realized. The SatisfactionIndex is introduced into the scheduling of distributed resources, in which the weighted formula is determined by priorities. A case study has been undertaken and preliminary results show that the proposed solution can effectively support the cloud simulation and efficiently meet tenants' personal requirements.

The framework monitors, detects and scheduling the system resource performance.…”
