I’ve been a huge fan of DigitalOcean for many years, and one of my SaaS businesses, AwardFares, has lived there for the past 5 years. We initially ran everything on a couple of Droplets (Ubuntu VPS that we managed ourselves). When DigitalOcean announced their app platform we immediately migrated our app to that, reducing devops to nearly zero. Our database, however, remained as a single mongodb instance running on a self-managed VPS.
