A Survey on Fault Tolerance and its Techniques in Cloud Computing

Abstract

Cloud Computing is an auspicious computing platform for both commercial and non-commercial computation clients. It delivers services to the users transparently without their need to know the details of the underlying software and hardware. One of the crucial issues in cloud computing platforms and applications is fault tolerance. It is a major concern to guarantee availability and reliability of critical services as well as application execution. Fault tolerant system is one that has the ability to recover from a catastrophic failure without disrupting its operations. Fault tolerance techniques are used to minimize failure impact on the system and application execution by predicting failures and taking an appropriate action before failures actually occur.
