The image shows a customer data center with a subnet that contains business service providers and Oracle Cloud Infrastructure (OCI) service consumers. A customer premises equipment uses site-to-site VPN or OCI FastConnect to connect to a dynamic routing gateway within an OCI region tenancy.

Within the OCI tenancy is a virtual cloud network (VCN) with an availability domain. There are three subnets within the VCN:

Subnet A (Oracle Integration Cloud Service connectivity agent)
Subnet B (Private endpoint IP)
Subnet C (OCI API Gateway Gateway)

There is a service gateway within the VCN that connects to Oracle Integration Cloud Service and an Oracle Services and Utilities Network with these other Oracle services:

OCI Functions
OCI Generative AI
Oracle Cloud Infrastructure AI Services
Oracle Integration Cloud Service
Oracle Digital Assistant
Oracle Machine Learning
OCI Identity and Access Management and policies
