I checked Google Cloud and Amazon AWS, and oh boy is the pricing so goddamn confusing. I'd rather get billed a known monthly amount than an obscure hourly rate.
I think I will stick with simpler approaches. I will use one VPS for the database, and a cloud storage solution for data storage (my data will not be too big).
What do you think about the
$10/mo Standard Droplet by DigitalOcean ?
Their cloud storage "Spaces" seems reasonable aswell, what do you think?
Fabric looks a lot like Firebase. But afterall, I don't think I'll go for a server-less approach for this project.
A critic on Firebase (I'm not saying it's a bad service, neither are they):

I'll check how pricing goes for analytics and crashlytics with both Firebase and Fabric.
