If your "db cluster" is split into containers on one VM as you would do in any other cloud (because VMs are expensive), then you would have the same problem.

Does it? I don't think so. I've worked with Oracle's stuff and the only real difference between Oracle Cloud and other clouds is that Oracle cloud is more expensive overall. There's nothing stopping you from running virtual machines and kubernetes in the same way you'd run it in any other cloud.
