Description of the Illustration single_availability_domain_jd_edwards_deployment_withCallouts-networking.png

This image shows a diagram of the deployment of a JD Edwards EnterpriseOne application in a single availability domain while ensuring network connectivity.

The architecture consists of a virtual cloud network (VCN) with the bastion host, load balancer tier, administration tier, presentation tier, integration tier, middle tier, and database tier placed in separate subnets of the VCN in a single availability domain.

The administration tier within the availability domain contains Fault Domain. Fault Domain contains provisioning server, deployment server, and development server.

The presentation tier within the availability domain contains Fault Domain 1 and Fault Domain 2. Each Fault Domain contains Java application server, application interface services server, business services server, real-time events server, BI publisher server and application development framework server.

The middle tier within the availability domain contains Fault Domain 1 and Fault Domain 2. Each Fault Domain contains enterprise server.

The database tier within the availability domain contains database server.

The bastion host receives requests through the dynamic routing gateway (DRG) and internet gateway. The DRG is the gateway that connects your on-premises network to your cloud network. To enable communication between the DRG and the customer-premises equipment, use IPSec VPN or Oracle Cloud Infrastructure FastConnect. To access your bastion host from the internet, set up an internet gateway (IGW). An IGW is a software-defined router that provides a path for network traffic from your VCN to the internet. You can access the instances in private subnets over port 22 through the bastion host or the DRG if you have set up an IPSec VPN tunnel between your data center and Oracle Cloud Infrastructure DRG.

There are six numbered callouts on the illustration:
  1. Dedicated Network Access via FastConnect
  2. Secure Network Access via IPSec VPN
  3. Built-in, Pre-Configured Oracle Cloud Infrastructure Load Balancing
  4. Secure Access to Any Tier via the Bastion host
  5. On-Cloud Network Isolation via Virtual Cloud Network
  6. Multiple Internal Firewalls
Each callout is described in the surrounding text.
