If you allocate multiple J2EE servers, you can configure multi-tenancy with the business processes (applications) partitioned for every tenant by effectively utilizing the host resources. You can set up Web front system that supports multi-tenancy by allocating multiple J2EE servers and adding a group of logical servers, including J2EE server, based on the single Web front system.

Example of system configuration

The following figure shows an example of configuring a Web front system that supports multi-tenancy by allocating multiple J2EE servers:
