ABSTRACT

Fault tolerant systems are necessary to be there for distributed databases for data centers or distributed databases requires having fault tolerant system due to the higher data scales supported by current data centers. In a large distributed database usually data resides on servers which are dedicated servers having backups. Therefore, large amount of servers are used for this purpose. In this paper it is proposed that instead internet can be used as backbone where Infrastructure-as-a-service (Iaas) service of cloud can be used for storage servers. The advantage of this will be that storage location is abstracted and database can be accessed from anywhere. However while the storage allocation is abstracted it also brings in performance concerns in a multi tenant cloud environment where by most of the cloud consumers are geographically dispersed. Recent large Web applications make heavy use of distributed storage solutions in order to be able to scale up. Here we propose that static distributed database is spread over cloud making database dynamic.
