I believe the problem has now shifted to a slightly higher level and especially when working in a microservice/containerized world. For example, given the number of specialized services you mentioned, we see more applications with polyglot persistence stacks underneath. If they form a part of the same application, how do you collectively manage them? What does it mean to take a consistent snapshot? These and a bunch of other similar questions need to be answered.

There is some work we are doing (https://kanister.io) to help with these issues but there are a lot of emerging solutions in this space. Look at CNCF's landscape for some more detail.
