Setting up Site-to-Site VPN on Oracle Cloud Infrastructure offers several key benefits. First, it provisions redundant VPN tunnels, ensuring high availability and resilience of the VPN connection. This means that if one tunnel goes down, traffic can continue to flow through the other tunnel, providing greater reliability. Second, customers have the flexibility to configure the VPN using either static or dynamic routing (BGP), allowing for more efficient and scalable network management. These features collectively enhance the operational efficiency and robustness of the cloud network.
