Oracle Cloud Infrastructure FastConnect provides an easy way for you to connect your on-premises network to Autonomous Database using FastConnect Public Peering. FastConnect provides higher-bandwidth options, and a more reliable and consistent networking experience compared to internet-based connections.
Use FastConnect to access public services in Oracle Cloud Infrastructure without using the internet, for example, access to Object Storage, or the Oracle Cloud Infrastructure Console and APIs. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet. With FastConnect, that traffic goes over your private physical connection.
