It is a pilot project idea running deployment in a microservice platform. The metadata frontend proxy is a web related gateway to reach backend services from the public internet via http/https.

The proxy service is complex and has many parameters to configure by users.

There is three important parts

core-dns service which is needed for stable proxy availability
public proxy service (1 haproxy loadbalancer and 2 haproxy backend proxies)
smarthost proxy service (1 haproxy loadbalancer and 2 nginx backend proxies with builtin SSL certificates termination processes)

All the proxies support the proxy protocol which is mandatory but not needed any configuration settings from the backend www services or another services also.
