Multi-region OCI architecture for an AI video intermediary platform spanning ap-tokyo-1 with dual availability domains, public-facing WAF and CDN tiers, and private application and data layers. Traffic flows from creators and viewers through OCI WAF and CDN to Flexible Load Balancers, then to API Gateways and App Servers in private subnets, which orchestrate OCI Functions, OKE media services, and external AI APIs for video and image generation. Data persistence uses ATP primary-standby pairs for prompt storage, NoSQL for user sessions, Object Storage for video assets, and OCI Vault for secrets, all monitored via OCI Monitoring, Logging, APM, and Cloud Guard. This architecture demonstrates high-availability, secure multi-tier design with integrated generative AI workflows ideal for platforms requiring real-time video processing and user session management.
