Abstract: Methods and systems for database migration from a multitenant database include taking a snapshot of an original database to be migrated with a hot backup process, such that the database is still capable of answering queries during the hot backup process; maintaining a query log of all queries to the tenant database after the hot backup process begins; initializing a new database at a target server using the snapshot; replaying the query log synchronize the new database with the original database; and answering new queries with the new database and not the original database.

Abstract: A computer implemented method for cloud bursting applied to a database includes employing a database live migration using a database hot backup capability to support database cloud bursting without client service interruption in multitenant databases, ascertaining a critical time to start/redo the database cloud bursting to a public cloud so as to meet a service level agreement SLA while leveraging a private cloud for the database to a maximum level, and determining tenants of the database to burst into the public cloud to responsive to costs and benefits.
