I was wondering what the cheapest option is to host Discourse. I have seen a lot of sites that say 6gb of ram for $5-10 per month (http://vpsdime.com/) but they never end up having the correct version of kernel.
The only “cheap” option I have found is Digital ocean with $10 per month.
Try vultr. They offer a bit more for the same price as DO. However, they have a highly strict anti-spam policy and require you request your mail-related ports opened manually by them. Personally, that’s a plus because I don’t want their IP blocks poisoned by bad behavior, which affects me in the long run.
