Hybrid network architecture connecting on-premises data center to OCI via FastConnect private peering and IPSec VPN backup. Traffic flows from the customer data center through CPE and firewall to OCI's DRG, then distributes across DMZ, distribution, access, and database subnets with load balancing, WAF, and NSG controls. This design provides redundant connectivity, network segmentation, and secure access to Autonomous Database and Oracle SaaS applications. Fork and customize this diagram on Diagrams.so to match your CIDR ranges, FastConnect port speed, and regional topology.
