Those days I had to implement an Oracle Cloud "IAAS Classic" solution for databases and applications with DR environments, considering the primary region as Ashburn (uscom-east-1) and the standby region as Chicago (uscom-central-1). To make both regions talk securely over the internet, I had to implement a VPN connection between both regions.
Before stating everything, I had to check that the connection between both regions would be large and fast enough to ensure the redo stream data generated on the instances running on Ashburn DC could be transferred to Chicago DC, with no delays. And vice-versa.
So, to measure the bandwidth between both DCs I used iperf3 utility, increasing the number of parallel connections from 1 to 100, and calculating the average speed in 1 minute frame. Please note that this test was performed using Public IP address, bypassing the VPN layer.
Below are the result tests of Total Bandwidth x Number of Connections:

Conclusions:
- The connection speed between 2 servers in those regions tend to stabilize at 5.15 Gbits/sec when 40 parallels or more connections are opened.
- One single connection doesn't perform faster than 0.635 Gbits/sec, so it's better to configure your database to do parallel redo shipping when your redo generation is bigger than that. Configure the number of connections based on the database redo generation and the graph above.
- Same thing applies for application DR. Whatever tool you are using, consider always parallel.
- Oracle probably has a backbone and do internal routing of connections involving Public IPs of both regions, to achieve this ~ 5 Gbits/sec bandwidth.
