In a production environment, a BigchainDB node should have several other components, including:
* nginx or similar, as a reverse proxy and/or load balancer for the web server
* nginx or similar, as a reverse proxy and/or load balancer for the Gunicorn server(s) inside the node
* An NTP daemon running on all machines running BigchainDB code, and possibly other machines
* A RethinkDB proxy server
* A RethinkDB "wire protocol firewall" (in the future: this component doesn't exist yet)
* Scalable storage for RethinkDB (e.g. using RAID)
* Monitoring software, to monitor all the machines in the node
* Configuration management agents (if you're using a configuration managment system that uses agents)
* Maybe more
