Perhaps I'm just a grump, but when the article says "couldn't find instructions for installing WeKan on other cloud providers like Vultr or DigitalOcean" did anyone else groan a little bit.
Heroku is a cloud provider. Vultr and DigitalOcean sell virtual private servers, which are pretty much just full servers virtualized. Follow any instructions anywhere for installing a Meteor app on a linux box and there are your intructions.
I really am prepared to be downvoted for a "damn kids get off my lawn" moment ... but sheesh, it's almost as though cloud vocabulary has numbed us to what a service is actually providing.
