I'm trying to run a side project at a low rate, which is usually why I go to DigitalOcean - it's much cheaper, than, say, spinning up a bunch of Heroku dynos. In fact, I just moved a project from Heroku to DO to go from a $14/mo hosting bill to $5/mo on the cheapest VPS.
My one problem has been Postgres - I don't want to self-manage a database. However, Cloud SQL is ~$9/mo at the cheapest, and RDS/Lightsail are both $15/mo at the cheapest. I'd really been hoping that DO would provide a lower-cost alternative.
I'm really sad that the pricing structure doesn't bring managed databases down to hobby-tier. I don't even want a free offering; I'm happy to pay gig of space for $5/mo to run in perpetuity, with restrictions on backup retention or something.
Right now, if I'm an actual startup or even bootstrapped company with money, I see _zero_ reason to use DO's offering over your more-established competitors, and as a hobbyist user, I can't justify spending money on it for a no-income side project.
