To a limited extent it is possible to run other services (e.g., databases or in-memory caches) in support of your web site. However, we only allow HTTPS (and legacy HTTP) services (e.g., websites) to be accessed from outside our network. A partial list of servers that will not work with our system includes:
- Live streaming
- Non-web-based MUD and gaming servers (including Minecraft)
- Voice/video chat servers not based on WebRTC
- email servers (SMTP, POP, IMAP)
- anonymous FTP servers
- IRC bots and servers (though many web-based chat programs do work)
The bottom line is that if a service speaks the HTTP protocol on TCP ports 80 or 443, it is likely to work. If it doesn't, it definitely will not.
