I'm running NodeBB for my motorcycling forum at https://www.sportbikes.ws
What's fun about this installation is that I'm using AWS with an Elastic Load Balancer in front of an Auto-Scaling group. NodeBB source is sitting on a common NFS mount using Elastic File System. The t2.micro instances bootstrap themselves and mount this NFS share, then fire up NodeBB and register themselves behind the load balancer. They connect to an ElastiCache redis cluster. I'm also using AWS Kinesis to land events from nginx and syslog from each host into ElasticSearch (by way of an AWS Lambda which beats up the log data a bit) to visualize with Kibana.
Admin Dashboards by way of AWS's implementation of Kibana in their ElasticSearch: (Pardon the nginx error count - I just went through an upgrade to 1.5.1 and it got a bunch of Bad Gateway errors in the logs ... which showed up on the dashboard)
