What is the purpose of a Dynamic Routing Gateway (DRG) in OCI?

The purpose of a Dynamic Routing Gateway (DRG) in Oracle Cloud Infrastructure (OCI) is to enable communication between on-premises networks and Oracle Cloud Virtual Cloud Networks (VCN). The DRG acts as a virtual router that allows for seamless connectivity between your on-premises data center and your cloud infrastructure.

This functionality is essential for organizations that wish to extend their existing networks into the cloud, allowing for hybrid cloud architectures where resources on-premises and in the cloud can communicate effectively. The DRG supports various types of connections, including FastConnect for dedicated private connections and VPN for secure encrypted tunnels over the internet.

By facilitating this connectivity, a DRG plays a critical role in scenarios where data needs to flow between on-premises applications and services running in the cloud, providing a secure and efficient routing system. Understanding this function is vital for architects looking to design and implement cloud solutions that integrate closely with existing infrastructure.
