Abstract
Reliability is the cause of concern during execution job over the cloud. Reliability enhancement strategies have been researched over that provides mechanism to conserve cost during allocation of job to virtual machines. Data Centre resource consideration is critical in allocating jobs that require prior knowledge of resources required by jobs. To ensure reliability, fault tolerant allocation strategy must be created. This paper presents comprehensive analysis of techniques used to ensure effective allocation off jobs that enhances reliability. Primarily this paper studies and surveys the techniques of checkpointing and replication for the sake of ensuring fault tolerance in cloud computing. Parameters considered for reliability includes mean time between failure and cost. Parametric comparison presented indicates adaptive framework including multiple strategies or hybridization better performance.
