Storage itself is a complicated problem domain, one that is easily dismissed until you actually have to deal with it in gory detail.
K8s grew organically here, and thus the seams show. It’s getting better every release, particularly being able able to dynamically provision and schedule storage to pods in a “zone aware” manner, which has been tricky.
The deeper issue issue is we are spoiled for choice on storage engines. Using Ceph for random access r/w low latency block storage I wouldn’t wish on my worst enemy, for example. But it’s hard to distinguish hard numbers for comparative purposes.
