What is the purpose of an OCI Dynamic Routing Gateway?

The purpose of an OCI Dynamic Routing Gateway (DRG) is to facilitate secure connectivity between Oracle Cloud Infrastructure and an on-premises data center or environment. By utilizing a Dynamic Routing Gateway, you can establish a Virtual Private Network (VPN) or a FastConnect connection, allowing data to flow securely and efficiently from your local infrastructure to resources hosted in OCI. This connectivity is essential for organizations that wish to maintain hybrid cloud architectures, where some workloads remain on-premises while others are migrated to the cloud.

The Dynamic Routing Gateway acts as a bridge that enables the routing of traffic between the OCI Virtual Cloud Network (VCN) and your on-premises network, ensuring that your compute instances can communicate with local resources seamlessly. This setup is particularly valuable for handling sensitive data that must be managed on-site or applications that require low latency access to on-premises services.

In contrast, options like enabling compute instances to connect to Object Storage privately, connect to the internet, or connect solely to the internal network do not adequately encompass the primary role of a DRG, which is specifically designed for establishing and managing secure connections between cloud resources and external networks.
