We just published a new article on the official CNCF Blog about the potentials opened by generalized multi-cluster topologies and comparing different approaches with Liqo.
This article addresses the differences among different existing approaches to multi-cluster (with comparison matrices) and explains why we think that the cluster peering provided by Liqo is really useful for building multi-cluster topologies.
Thanks for your interest in our project!
