Abstract:
Failures are usual rather exceptional in cloud computing
environment. To access from the nearby site, the often used data should get
replicated to multiple locations to compose the users to advance the system
accessibility. A challenging task in cloud computing is to decide a sensible
number and right location of replicas. At this point, we propose an adapted
dynamic data replication approach to decide a sensible number and right
location of replicas and we compare both the adapted dynamic data replication
approach and normal dynamic data replication approach. The normal dynamic data
replication approach has three dissimilar stages which are the recognition of
data file to replicate, number of replicas to be created and placing new
replicas. We adapt the popularity degree in the initial stage of normal dynamic
data replication approach and also we consider the failure probability for
replica factor calculation and the other two stages are related to the normal
dynamic data replication approach. When we update the major data center we
moreover integrate the synchronous and asynchronous updation of replica data
file.
