A Replica Distribution Based Fault Tolerance Management For Cloud

Abstract: Cloud computing now a day's become most popular and reliable computing technique for organizations and individuals. In the cloud environments, data availability and backup replication are critical and complex issues in the an efficient fault tolerance policy is the major. Fault tolerance policy is the strategy in action when a fault occurs in the system. Taking backups is the one of the most usual solution of keeping the data safe out of these faulty conditions, But sometimes traditional schemes and backup servers might get into bottleneck conditions due to their replica management schemes. CSP has to adopt a fault tolerance policy to ensure continues delivery of services. There are two main categories policies that are proactive and reactive fault tolerance, both have different advantages in different situations. Our research introduces a new approach as a fault tolerance policy, which is having characteristics of both the above mentioned policies. In our approach replica distribution and retrieval is the functional areas
