ABSTRACT In this talk you’ll explore how to run a PostgreSQL cluster across multiple Kubernetes clusters. Learn what challenges arise when using asynchronous streaming replication in a set of Kubernetes clusters spanning across several geographical regions. It will be discussed how such a topology can be established using Kubernetes and Kubernetes Add-Ons. You will learn which qualities the system has, where such a distributed system plays its strengths and where it may be problematic to use it. At the end of the talk you will have an increased understanding about how to create multi-regional data service instances using PostgreSQL as an example.
