It really depends on what are the requirements of the app.

What are they? What do you need to do manually when scaling?

Hi,

These are nosql db, whenever storage get fill need to scale .

Online PVC expansion is one option but not sure, we can use it for cinder as backend .

It’s highly database dependant. You’re best bet would be to look at an operator or database with some logic for doing that sort of thing. A good example would be vitess + the vitess operator.
