dcerberus.com sits behind Nginx, which also terminates TLS at this time. For cost reasons, there is no load balancer currenlty in use in AWS at this time.
Nginx is vanilla, installed through the standard Ubuntu packages.
The Nginx config is below.
Note that rate limiting is not (yet) enabled. That may be revisied in the future.
