The image shows a high availability JD Edwards deployment in a single Availability Domain in an OCI region with Oracle Autonomous Database on Dedicated Exadata Infrastructure.

This deployment has a Production and two Non-Production environments. All the instances in the Production as well as Non-Production environments including load balancer, web tier, application and database are deployed in a private subnet.

In the Production environment, Presentation tier or Web tier contains four instances which are load balanced by a single Production load balancer.

Each Web tier instance consists of a single Application Interface Services (AIS) Server, Standard HTML Server (Standard HTML), and Dedicated HTML Server (Dedicated HTML). As per the recommendation, all the Web tier components are installed in each Web tier instances (or VM) and scaled horizontally by deploying redundant instances of every component. High availability can be achieved by spreading the multiple VMs across different fault domains.

The Application or middle tier contains four logic servers and batch servers. The logic server and the batch server can be hosted on the same enterprise server instance. However, it is recommended to set up the logic server and the batch server on separate enterprise server instances.

The JD Edwards EnterpriseOne application server connects to the Autonomous Database. Within the Production Autonomous VM cluster, it has a single container database and one pluggable database. Note that you can have a maximum number of five schemas distributed across one or many database instances.

The Non-Production section of the architecture has two environments. One is a multi-instance deployment and another is single instance deployment for both Presentation and Middle or Application tier.

Additionally, One-Click Provisioning Server and Deployment Server are deployed in the Admin subnet. It also has an OCI Bastion which can be used for a secure SSH connectivity. Depending on your requirement, you can use either 'Self Service Bastion' or 'Bastion as a Service'. Optional JD Edwards EnterpriseOne components are hosted in the Admin subnet.
