A REVIEW ON COST OF DYNAMIC MIGRATION OF CONTENT AND LOAD BALANCING DISTRIBUTION SERVICES INTO HYBRID CLOUDS

Cloud computing technology is impetuously used to access scalable resource for various applications. Cloud computing provide services (e.g. SaaS, PaaS, Iaas) to end user to complete their need. A content distribution service is a major part of popular Internet applications. Content provider switches a content or data dynamically on different cloud. There are two tasks one is migration of contents to cloud storag e, second to distribute their web service load. In proposed system we used hybrid cloud. We are utilized both cloud private cloud as well as public cloud. One data center is allocated each region. The challenge is utilization of the cloud as well as their existing on-premise server infrastructure, to provide content requests with service response time guarantee at all times as well as the minimum operational cost. To minimizing operational cost by using the Lyapunov optimization technique. A dynamic control algorithm is design for load balancing on cloud servers. A submit contents and dispatches requests on various data centers to minimize overall operational cost over time.
