The image shows an architecture diagram that demonstrates how containerized applications on Google Cloud integrate securely with Oracle Autonomous Transaction Processing.

On the left, there is a section labeled "Cloud Run" which contains three "Container Application" instances, each with its own "Oracle REST Data Service with MongoDB API." This indicates a scalable deployment of applications emulating MongoDB APIs on Google Cloud Run.

These container applications connect to a "Primary Region Application Subnet" using a "Serverless VPC Access connector," which securely bridges the applications to private network resources.

An arrow labeled "Private connectivity" extends from the Serverless VPC Access connector to the right, connecting to a section labeled "Oracle Database@Google Cloud." Within this section is an "OCI child site," which contains a "VCN" (Virtual Cloud Network) and a nested "Subnet." Inside the subnet is the "Oracle Autonomous Transaction Processing Serverless" database service, visually indicating the private, secure networking layer.

This architecture highlights a pattern where cloud-native, containerized workloads on Google Cloud can use private networking to interact securely with high-performance, serverless Oracle databases in an OCI-managed child site - enabling enterprise-grade connectivity and compatibility with MongoDB APIs.
