Etcd is a strongly consistent, distributed key-value store. It provides a reliable way to store data that a distributed system or cluster of machines needs to access.

Instead of connecting directly to the database server, you can set up HAProxy so the application connects to the proxy instead. The proxy then forwards the request to Postgres. When you use HAProxy for this purpose, you can route read-only requests to one or more replicas for load balancing.

We strongly suggest using HAProxy to avoid data loss in case of split-brain.

You can install HAProxy as an independent server, but you can also install it on the application server or the database server.
