According to various example embodiments, a request transmitted from a client and directed to a service application is intercepted. A logical database (DB) host specified by a hint value included in the request is then identified. Moreover, a target physical DB host is identified, based on the identified logical DB host and DB host mapping information. Thereafter, the request is routed to an instance of the service application co-located with the identified target physical DB host at a particular data center. |
