Cloud computing provides access to large pool of data, applications and computational resources. Many researchers have been proposed several open-source Infrastructure-as-a-Service (IaaS) cloud management frameworks (e.g, Eucalyptus, Nimbus, OpenNebula). However, all these systems have limited scalable and fault-tolerance support. Now, fault-tolerance in new computing environments has become a critical requirement. Checkpointing and rollback recovery is a common approach to achieve fault-tolerance. In this paper, the authors propose the fault-tolerance management framework for private cloud development based on Eucalyptus - an open-source framework for cloud computing that implements what is commonly referred to as Infrastructure-as-a-Service (IaaS).
