The image shows an On-Premises Data Center with User Groups connected to an OCI Region via Internet Gateway.

Users Groups are internal users or business analysts who will access the application via web or VPN. The Internet Gateway provides access to the OCI environment from external networks (e.g., employee web browser access). In the OCI Region, all resources exist in a compartment called OWNTESTHUB and are distributed across three Fault Domains for high availability. The entire architecture is built inside a secure virtual network. Oracle Cloud Infrastructure Web Application Firewall (WAF) protects from threats like SQL injection, DDoS, and so on.

The Load Balancer distributes incoming traffic across backend web, API servers for scalability and availability. WEB API (VM.Standard.E5.Flex) hosts the front end and REST APIs for the OwnGPT application. AIRFLOW (VM.Standard.E5.Flex) manages task orchestration, scheduling jobs (e.g., model training or ETL). OWNGPT (VM.GPU.A10.2) has a GPU-accelerated VM that runs the OwnGPT model, ideal for real-time AI inference.

Oracle Autonomous Data Warehouse stores ERP related structured data (AP, AR modules) for fast querying. Oracle E-Business Suite APP (VM.Standard.E5.Flex) uses backend services for Oracle E-Business Suite (likely running connectors or middleware). OCI File Storage provides shared storage, useful for Airflow DAGs, app artifacts, or logs.

OCI Identity and Access Management controls user roles, policies, and secure authentication. Service Gateway connects to OCI services like OCI Object Storage without going over the internet. OCI Object Storage is used for storing model checkpoints, training datasets, logs, or archives. The NAT Gateway enables private subnet VMs to initiate outbound internet traffic securely. Response Generation Model extracts relevant data, interprets context, and generates a human-readable response without requiring manual report generation.
