"Nothing", you might be thinking. At least I used to: it's okay for deploying application servers in an "elastic" capacity, but not for databases, which are meant to be stable and faultless. However, while Kubernetes environments remain very dynamic, it evolved to support stateful applications better and now counts with an enthusiastic Data on Kubernetes (DoK) community that keeps increasing in...
