A Fuzzy Approach to Fault Tolerant in Cloud using the Checkpoint Migration Technique

Fault tolerance is one of the most important issues in cloud computing to provide reliable services. It difficult implement due dynamic service infrastructures, complex configurations and different dependencies. Extensive research efforts have been made fault environment. Many studies focus only on detection do not consider tolerance. For this reason, paper, addition recognizing nature fault, a fuzzy logic-based approach proposed an appropriate response increase Checkpoint-based migration technique used Using checkpoint during can reduce time processing costs balance load between virtual machines event fault. The simulation performed according data center Vietnam Telecommunications Company (VDC). results method period 60 minutes show 98.03% accuracy, which 4.5% 4.1% superior FLPT PLBFT algorithms, respectively.
