Methodical Review on Various Fault Tolerant and Monitoring Mechanisms to improve Reliability on Cloud Environment

Background/Objectives: Cloud computing is an emerging area that is currently pulling towards many of us. Cloud deployment is a difficult task in this layered structure. Handling the cloud environment itself an optimally a challenging job. This can be made feasible by using fault tolerance and monitoring services. Methods/Statistical Analysis: Fault Tolerance (FT) facilitates the process or the component to work smoothly even though in the occurrence of failure. Monitoring is a technique collects the information and to predict the fault before it occurs. Proactive and reactive measures can take place to run the cloud environment with tolerance in failure occurrence. Reviewing the potential of FT and monitoring services is to make out the technique that serves in certain purpose. Fault tolerance systems are important for both cloud provider and cloud customer. Findings: Based on this idea, this paper provides the different or diverse fault tolerance and monitoring mechanism to improve the reliability in a cloud environment. Applications/Improvements: It presents the information about the various techniques and methods used in the FT and also a future research direction in cloud FT.
