This image shows the primary on-premises architecture where the primary Oracle WebLogic Server hosts, database hosts, and databases are on-premises. Data enters the Customer Data Center and Customer Network from wlsfrontend.example.com.

The following are located in the on-premises data center:

• Load balancer (10.10.10.10)
• WebHost1 (host1.myopnetwork.com, 10.10.10.11) and WebHost2 (host2.myopnetwork.com, 10.10.10.12)
• Oracle WebLogic Server with APPHOST1 (host3.myopnetwork.com, 10.10.10.13) and APPHOST2 (host4.myopnetwork.com, 10.10.10.14)
• Oracle RAC with DBHOST1 (dbhost1.myopnetwork.com, 10.10.10.15) and DBHOST2 (dbhost2.myopnetwork.com, 10.10.10.16) and PDB1

Data flows both directions between APPHOST1 and APPHOST2 and between DBHOST1 and DBHOST2.
