Oracle's central hub for connecting virtual cloud networks and on-premises networks. Like having a central switchboard that connects all your different network locations.
Global enterprises use DRG to connect their Oracle Cloud regions with their on-premises data centers securely.
All are hub-and-spoke connectivity services that centralize routing between multiple virtual networks (VPC/VNet/VCN) and on-premises networks via VPN or dedicated circuits. OCI DRG is the routing hub for VCN attachments and on-prem connectivity; AWS Transit Gateway and Azure Virtual WAN hubs provide similar centralized routing; GCP Network Connectivity Center provides a hub for hybrid and multi-VPC connectivity.
