Performance Enhancement of Cloud Datacenters Through Replicated Database Server

Cloud computing has risen as a new paradigm providing computing, resources for networking, and storage service across the network. Data replication is phenomenon which brings available reliable data (e.g., maybe databases) nearer to consumers cloud applications) overcome bottleneck becoming suitable solution. In this paper, authors study performance characteristics of replicated database in centres improves QoS by reducing communication delays. They formulate theoretical queueing model system considering arrival process Poisson distribution both types client request, such read write applications. solve proposed with help recursive method, relevant matrices are derived. The evaluated results from mathematical extensive simulations unveil guide providers modelling future solutions.
