I’ve only ever used Oracle cloud in an enterprise environment, so I don’t know what features you have available. I’m also much more familiar with AWS. But you should be able to create a proxy endpoint in your present region, and traverse the cloud providers internal network. That would likely improve your streaming. You could also create a VPN endpoint in your current region and terminate your traffic inside your cloud providers network, but that would add protocol overhead.

I would look at tools like iperf to look at your packet loss because being further from your server will increase latency, but shouldn’t impact the streaming unless you also have packet loss.
