About This Architecture

Hub-and-spoke VCN topology with Dynamic Routing Gateway (DRG) centralizing connectivity across production, non-production, DR, and SDDC environments on Oracle Cloud. Multiple VCN attachments (PROD-OCI-VCP, NPROD-OCI-VCP, PROD-SDDC-VCP, DR-REALIZE-VCP) connect to a central DRG hub, enabling transitive routing and simplified network management. Dual FastConnect circuits (RT07 active, RT08 standby) provide redundant on-premises and multicloud connectivity with failover capability. This architecture reduces operational complexity, improves blast radius isolation, and supports hybrid cloud scenarios across 10.207.0.0/16 and 10.0.0.0/8 address spaces. Fork this diagram on Diagrams.so to customize attachment policies, add route tables, or model failover scenarios for your OCI environment.
