### Load balancing
Load balancing is supported by `group`.

Proxies in same group will accept connections from port 80 randomly.
For `tcp` type, `remote_port` in one group shoud be same.
For `http` type, `custom_domains, subdomain, locations` shoud be same.
### Health Check
Health check feature can help you achieve high availability with load balancing.
