specs for all servers: OS: Ubuntu 14.04 PN: Yes RAM: 512MB, except webserver which is 2GB.
God day! I’m very new at setting up multiple servers to create a functioning environment. In front i have NGINX on a 512MB server serving traffic over ssl. It also proxies all traffic for my mailserver and my webservers.
Here’s my current configuration: image
Here are my questions to you pro’s :)
- Now want a email nodejs app running to view emails send them and such, should i put this on my mailserver or my webserver?
- Should I split my webserver into smaller servers?
- If i do setup a nodejs app for mails on my webserver how should it interact with the mail server to load emails, sockets?
- should i ghost my servers behind the nginx, except for ssh port?
- is it smart to tunniel my ssh connection through the nginx server to the servers behind it?
- how should i store my emails, nosql, or as every one else recomends; as files?
- tips to a newbie? :D

If you’re looking for a bit of a deeper dive, this series gets into details about building out a multi-server production application setups:
The one major drawback that I can see with how you’ve currently implemented your setup is that the Nginx proxy has become a single point of failure. If it goes down, you wouldn’t be able to reach any of your other service. Depending on how critical it is for these service to be highly available, you might want to consider setting something up using Floating IPs to build something with some more redundancy. Check out:
