The image shows the logical architecture underlying a deployment of the connectivity agent to handle hybrid integration. It contains four components:

• Oracle Cloud applications, particularly Oracle Fusion applications.
• An on-premises site, comprising customer systems and internal users.
• An OCI region, comprising logical layers and an integration instance, which itself contains a Oracle Integration instance. The Oracle Integration instance contains an agent. The logical layer also contains 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 agent.
• The internal users and external user both access Oracle Integration through the ID domain.
• Oracle Integration exchanges data with other Oracle cloud services on the Internet.
