 At Supabase, we use clustering in all of our Elixir projects which include [Logflare](https://github.com/Logflare/logflare), [Supavisor](https://github.com/supabase/supavisor) and [Realtime](https://github.com/supabase/realtime). With multiple servers connected we can load shed, create globally distributed services and provide the best service to our customers so we’re closer to them geographically and to their instances, reducing overall latency.

 To achieve a connected cluster, we wanted to be as cloud-agnostic as possible. This makes our self-hosting options more accessible. We don’t want to introduce extra services to solve this single issue - Postgres is the logical way to achieve it.
