The discussion revolves around installing Discourse on a regular VPS. Artashes expresses interest in migrating from vBulletin to Discourse but is concerned about technical requirements. itsbhanusharma reassures that a VPS with 2GB+ RAM and SSD storage should work well, noting that specifics are covered in the official installation guide. ashs adds that KVM virtualization is required and 1GB RAM is sufficient for lighter sites, suggesting more resources for higher traffic. Artashes confirms his VPS has 4GB RAM and plans to check if it supports KVM, noting low traffic levels.
I like the future-minded Discourse, and while I’ve also been following Flarum, which finally went stable recently, ideally I’d love to give feature-superior Discourse a shot by migrating from vBulletin.
However, my biggest issue is technical requirements. My community is sponsored with a VPS by a hosting company. I know DigitalOcean is recommended and if a regular VPS is employed, Discourse may run with problems.
Because I have the flexibility to customize this VPS to any specifications, what should these specs be that would guarantee good performance, if that’d even make a difference?
Discourse should run on any VPS that is using KVM for virtualisation (a quick way to check is to see if the host allows installing a custom OS) with 1GB of RAM.
If you have a particularly busy site you may benefit from more RAM and powerful CPU.
Do you know roughly how many pageviews you get daily?
