6f). Within the FTM framework, the notion of providing fault tolerance as a service can therefore be effectively realized for the cloud computing environment. Based on FTM’s delivery scheme, users can achieve high levels of reliability and availability for their applications without having any knowledge about the low-level mechanisms, and dynamically change the fault tolerance properties of its applications (based on the business needs) at runtime. 6F Replica Group n2 n3 25 Recovery Manager brings back node n1 to working state.

This model serves as an effective means of deriving the reliability and availability of the system because the failure behavior of both replicas can be taken into account. Moreover, as described earlier, the results of the Markov model analysis can be used to support the fault trees in characterizing the impact of failures in the system. Each state in the model is represented by a pair (x, y) where x 5 1 denotes that the primary replica is working and x 5 0 implies that it failed. 4A Markov model of a system with two replicas in active/semiactive replication scheme [12].

To address this issue, Remus asynchronously sends the disk state to the backup where it is initially buffered in the RAM. When the corresponding memory state is received, complete checkpoint is acknowledged, output is made visible to the user, and buffered disk state is applied to the backup disk. Remus is built on Xen hypervisor’s live migration machinery [21]. Live migration is a technique through which a complete VM can be relocated onto another physical host in the network (typically a LAN) with a minor interruption to the VM.
