I used to host comments on a free Discourse server, but after starting a consulting business, I've decided to move to a paid service. At the moment I'm using DigitalOcean because I can get a virtual machine capable of running Discourse for $12 a month. It's also easy to spin up new machines (AKA Droplets) and only pay for the time they are active. I got $200 credits for the first 2 months in order to try out the service. (If you want get the same deal, use my referal link.)
