Methods for enhancing a legacy single tenant application system to a multi-tenant application system with minimal changes

Abstract:

Systems and methods for accessing single-tenant databases comprising a multi-tenant aware cluster manager in communication with instances of single-tenant databases are described. The cluster manager can establish a uniform resource locator (URL) unique for each tenant to access the cluster manager. Each of the instances of single-tenant databases can include data for a corresponding tenant. The cluster manager can receive a request from a client to access a database corresponding to the first tenant. The request can include the URL established for the first tenant. The cluster manager can identify the first tenant based on the URL of the request. The cluster manager can obtain, responsive to identification of the first tenant, a tenant context of the first tenant from a storage. The cluster manager can access, using the first tenant context and responsive to the request, a first instance of the single-tenant databases corresponding to the first tenant.
