Fault tolerance in cloud computing environment: A systematic survey

摘要: Abstract Fault tolerance is among the most imperative issues in cloud to deliver reliable services. It difficult implement due dynamic service infrastructure, complex configurations and various interdependencies existing cloud. Extensive research efforts are consistently being made fault Implementation of a policy not only needs specific knowledge its application domain, but comprehensive analysis background prevalent techniques also. Some recent surveys try assimilate architectures approaches proposed for environment seem be limited on some accounts. This paper gives systematic elucidation different types, their causes used The presents broad survey frameworks context basic approaches, applicability, other key features. A comparative surveyed also included paper. For first time, basis an cited present as well recently published prime surveys, quantified view applicability presented. observed that primarily checkpoint-restart replication oriented target crash faults
