Enterprise customers experience growth in their cloud deployments,and more critical applications are increasingly deployed to the cloud. With this growth,you need to ensure that your cloud infrastructure is available and connected to your on-premises network in a redundant way so that it can support planned maintenance outages and unplanned downtime. The purpose of this document is to help you check your current deployment for redundancy or upgrade a single connection to Oracle Cloud Infrastructure to a redundant connection. It reviews some use cases and options for connectivity through FastConnect and through VPN Connect (IPSec VPN) over the internet. It assumes that you are familiar with routing protocols and concepts, IPSec VPN technology and configuration, and Oracle Cloud Infrastructure concepts and components.
