Can one Digital Ocean account host several instances of Discourse, and would each instance require an extra 2GB of RAM?

Hello. I’m looking to set up a bunch of bloggers, all with their own domains, under one instance of Discourse so that their commentariat is all connected. I was told by Discourse this wouldn’t quite be possible, but that (if I understood correctly) each blogger could have their own instance of Discourse and that “you could connect them by having one of these instances act as the SSO provider for the rest.” That being so, can one Digital Ocean account host more than one instance of Discourse, and if so, would each instance would require an extra 2GB of RAM, or just 2GB in total for no matter how many instances?

While it may be possible to do it with less, since the officially recommend method for installing Discourse uses separate docker containers I would recommend planning on at least 1-1.5GB for each. While you could likely better share resources among multiple instances by doing a manual installation directly on your droplet this method is not supported or well documented and could likely lead to problems finding answers if you ran into trouble.
