Hey everyone, As per the website (elastic and algolia comparison page), it’s possible to self-host SDN but all the references I could find point to using TS cloud. Do you know if that’s possible?

The term SDN is a Typesense Cloud thing. But you can run a globally distributed Typesense cluster yourself if you want to using the same binaries we publish open source. You would have to build your own infrastructure on top of them to support traffic routing, etc.

Does that mean that a single cluster can span multi-region with nodes in different regions or is the structure multiple clusters?

That would be up for you to decide
