Abstract

The past decade has witnessed the rapid development of cloud computing. Virtualization, which is the fundamental technique in providing Infrastructure as a Service (IaaS), has led to an explosive growth of the cloud computing industry. Fault-tolerance is a significant requirement of cloud computing due to the Service Level Agreements (SLA). In order to achieve high reliability and resilience of real-time systems in virtualized clouds, a Virtualization-based Fault-Tolerant Scheduling (VFTS) algorithm is proposed. In this paper, fault tolerance is implemented by using primary-backup approach. VFTS is designed for periodic and preemptive tasks in homogeneous environment. Simulation results demonstrate an impressing saving of processing resources compared with those needed by the dual-system hot backup approach, which proves the feasibility and effectiveness of the proposed VFTS algorithm.
