Abstract

Cloud Computing gives convenient, on-demand network access to shared pool of computing resources like network storage and servers. With On demand use, high scalability and low maintenance cost of Cloud computing more and more enterprises wishes to migrate their legacy application to the cloud environment. Cloud platform itself promises high reliability. And also ensures high quality of service. But due to complicated structure of enterprises application and also large no of distributed components of legacy application the things are becoming complicated. So while migrating any legacy application to the cloud becomes critical and challenging task. To improve reliability proposed system gives ROcloud framework i.e. Reliability- Based optimized framework. ROCloud improves the application Reliability by using Fault tolerance. ROCloudes includes two ranking algorithms. First Ranking Algorithm is used to rank components for the application when all their components of the application will be migra ted to the cloud. And second ranking algorithm is used to rank components those are hybrid application i.e. when only part of their components are migrated to the cloud. For components both the Ranking algorithms make use of the Application structure information and historical reliability information. On the basis of ranking results for the most significant components with respect to their predefined components Optimal fault tolerant strategy will be selected automatically.
