Cloud Databases: Future of Distributed Databases

Hardware failures in current data centers are very frequently because of high volume data scales supported. Data replication is the better option for this condition. Distributed database is a concept of distribution data storage at different remote locations. Many of servers are used to store these databases; therefore many of servers are used for this purpose. We can use internet as backbone where Iaas service of cloud can be used for storage servers. The advantage of this will be that exact data position need not be known and database can be accessed from anywhere. The geographical distribution of data locations is considered in this paper, it is proposed that distributed database at cloud which is a cost-efficient replication scheme across data centers that dynamically take the number of replicas employed per partition to the query load. Now a day’s large Web applications make heavy use of distributed storage solutions in order to be able to scale up. As data scales up its availability becomes more crucial and more important, as even reliable hardware may fail. Static database is converted to dynamic database when using cloud..
