A comprehensive survey of Fault Tolerance techniques in Cloud Computing

Fault tolerance in cloud computing platform is a crucial issue as it guarantees the availability, performance and reliability of the applications. In order to achieve the availability, reliability, performance, robustness and dependability in cloud computing, failure should be accessed and handled effectively. This paper discusses the better understanding of different fault tolerance techniques which are used according to their policies and tools. This paper also describes the comprehensive taxonomy of faults, errors and failures. The usage of taxonomy and survey results are not only used to identify the similarities but also to identify the areas requiring for future research.
