The image shows how to handle hybrid integration by deploying a private endpoint. It contains four components:

• Oracle Cloud applications, particularly Oracle Fusion applications.
• An on-premises site, containing internal users.
• An OCI region, comprising logical layers and an integration component, comprising an Oracle Integration instance. The region also contains:
  • A networking instance containing a private endpoint.
  • A systems instance containing private resources.
  • An ID domain.
• The Internet, which contains other Oracle cloud services and external users.

Traffic flows as follows:

• The on-premises customer systems exchange data with the Oracle Integration, which passes data through the private endpoint and on the private resources.
• The internal users and external user both access Oracle Integration through the ID domain, which directs traffic to Oracle Integration.
• Oracle Integration exchanges data with other Oracle cloud services on the Internet.
