A Study on Cloud Database

From the data management point of view, cloud computing provides full availability where users can read and write data at any time without ever being blocked. The acknowledgment times are almost stable and do not depend on the amount of associated users, size of the database or any added computing/communication constraints. Furthermore, users are freed for the burden of taking backups. If components fail, it is the responsibility of the service provider to replace them and make the data available using replicas in the meantime. This paper is a study on some of the popular Cloud databases.
