The balancerd service is a horizontally scalable, stateless, multi-tenant ingress router for pgwire and HTTPS connections.
It listens on pgwire and HTTPS ports. When a new pgwire connection starts, the requested user is authenticated with frontegg from which a tenant id is returned. From that a target internal hostname is resolved to an IP address, and the connection is proxied to that address which has a running environmentd’s pgwire port. When a new HTTPS connection starts, its SNI hostname is used to generate an internal hostname that is resolved to an IP address, which is similarly proxied.
