+### Drawbacks

+- [operational] it requires self-signed CA certs shared when running multiple
+Minio servers;
+- [operational] every X years it requires updating the CA certificate in the
+Traefik's (or any other reverse proxy) container;
+- [security] the CA key will have to be spread all over the environment.
