Database multiplexing architectures

A method comprising:

• within a group of two or more logical databases, each having a plurality of database nodes, the group of logical databases being part of a multitenant database environment that stores data for multiple client entities each identified by a tenant identifier (ID) having one of one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant database is a hosted database provided by an entity separate from the client entities, and provides on-demand database service to the client entities, using the tenant ID to determine a mapping between the tenant ID and one of the plurality of logical databases;
• utilizing a plurality of application servers coupled with two or more of the logical databases to service requests received from remote client device using the mapping to access a selected logical database corresponding to the tenant ID.

A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to:

• within a group of two or more logical databases, each having a plurality of database nodes, the group of logical databases being part of a multitenant database environment that stores data for multiple client entities each identified by a tenant identifier (ID) having one of one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant database is a hosted database provided by an entity separate from the client entities, and provides on-demand database service to the client entities, use the tenant ID to determine a mapping between the tenant ID and one of the plurality of logical databases;
• utilize a plurality of application servers coupled with two or more of the logical databases to service requests received from remote client device using the mapping to access a selected logical database corresponding to the tenant ID.

An apparatus comprising:

• means for using a tenant identifier (ID) to determine a mapping between the tenant ID and one of the plurality of logical databases within a group of two or more logical databases, each having a plurality of database nodes, the group of logical databases being part of a multitenant database environment that stores data for multiple client entities each identified by the tenant ID having one of one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant database is a hosted database provided by an entity separate from the client entities, and provides on-demand database service to the client entities;
• means for utilizing a plurality of application servers coupled with two or more of the logical databases to service requests received from remote client device using the mapping to access a selected logical database corresponding to the tenant ID.
