ABSTRACT THE NEW DIMENSION OF CLOUD COMPUTING HAS BRING US TO THE WORLD OF INFORMATION TECHNOLOGY. AND ALSO CLOUD COMPUTING PROVIDE A VARIETY OF BENEFITS LIKE FASTER, IN THE NEED OF PROVISIONING OF RESOURCES, REDUCED COST, MULTI-TENANCY, THERE ARE SAME RISKS AND FAULT RELATED WITH IT, THE KEY RESEARCH CHALLENGE IN CLOUD COMPUTING IS TO ENSURE CONTINUOUS RELIABILITY AND MAKE SURE AVAILABILITY OF RESOURCES PROVIDED,FAULT TOLERANT (FT) SYSTEM IN CLOUD COMPUTING THERE IS A NEED FOR A ROBUST TO BETTER UNDERSTAND FAULT TOLERANT IN CLOUD COMPUTING, IT IS IMPORTANT TO UNDERSTAND THE DIFFERENT TYPES OF FAULTS IN THIS RESEARCH PAPER, WE SHOW UP THE BASIC CONCEPTS OF FAULT TOLERANCE BY UNDERSTANDING THE DIFFERENT FT POLICIES LIKE REACTIVE FT…show more content…
Based on the services provided, Cloud is differentiated into Software as a Service Platform as a Service and Infrastructure as a Service In, Cloud providers develop, host and Operate domain speci fic applications which can be accessed by the end users on a pay-as-you-go demand basis. In, the platform is provided as service where application developers can build application without any stress of managing or buying large servers or underlying developing tools. And in, infrastructure resources like operating system, storage, processors and networking compo-nents are offered as service where companies can deploy and run random software. 1. Resubmission: When a fault is identify, the task issubmitted either to the same or to a different resource at aruntime without interrupting the workflow of the system Both proactive and reactive fault tolerance metho-dology have advantages and disadvantages, there are some test results which clearly points out that steps technique proactive fault tolerant method are efficient than checkpoint/restarttechnique reactive fault tolerant method Even though proactive And also it provide fault tolerance platform is capa-ble of executing messages using Message Passing Interface In order to hold fault tolerance in a Distri-buted Multithread. Check pointing is used to enables the end user pro-pose a fault tolerance modelin the cloud computing. In this model, the faults are managedbase on the re-liability of
