Efficiency (in term of time consumption) and effectiveness in resources utilization are the desired quality attributesudin cloud services provision. The main purpose of which is to execute jobs optimally, i.e., with minimumudaverage waiting, turnaround and response time by using effective scheduling technique. Replication providesudimproved availability and scalability; decreases bandwidth use and increases fault tolerance. To speed up access,udfile can be replicated so a user can access a nearby replica. This paper proposes architecture to convertudGlobally One Cloud to Locally Many Clouds. By combining replication and scheduling, this architectureudimproves efficiency and easy accessibility. In the case of failure of one sub cloud or one cloud service, clientsudcan start using another cloud under “failover” techniques. As a result, no one cloud service will go down.
