Recommended environment: Dual core CPU recommended 1 GB RAM minimum (with swap) 64 bit Linux compatible with Docker The above is for 1 domain, I assume. What are the minimum specs requirements for multisite discourse? If I want to host 2 domains, does it mean I will need at least 2GB RAM ? How about hosting 3 domains?

I found this Do I need a VPS for Discourse and do I host the main site on the same server? - #5 by Sander78 and it seems I can host 2-3 discourse sites on 1GB RAM droplet. Please correct me if I’m mistaken.

I would not recommend that, no. I’d say 512mb ram minimum for each additional community. So 1 GB to start with community 1, then + 512mb for community 2, + 512mb for community 3, etc.

If I’m not mistaken the recommended size for swap is always the RAM size. But hey, Google is my friend and I found this: http://wiki.linuxquestions.org/wiki/Partitioning_guidelines From the Swap space paragraph: Almost every Linux system will need swap space. The classic piece of advice is “swap should be double the amount of RAM you have”, though this is not a rigid guideline. Another guideline is to have at least 1x your RAM size, but this also isn’t a fixed, absolute requirement (this used to be necessary for linux, but not anymore for recent versions). It depends mainly on what applications you want to run. Applications like video/movie editing, 3d rendering, large image editing, database servers and web application servers can use a lot of memory and if you don’t have that as RAM, it will need a large swap space.

Let’s say, if I use 2GB droplet, for 2-3 sites, do you recommend to have 2GB swap as well?
