For cloud PaaS solutions, you are missing two of the most attractive offers in my opinion, namely Scaleway and Upcloud. They are not “direct to OpenStack” solutions which is not necessarily a disadvantage cause OpenStack isn’t that user friendly. But they seem fresh and offer plenty, with Scaleway doing lots of features and Upcloud being more flat, also regarding pricing.

How is it different or better?

It’s still like that. Those additional things are instagram.

What does it do? Is it a direct alternative for something?

Source?

Do they support some kind of CI/CD? Or is there maybe an external free service that can be recommended? It’s pretty much just for building some docker images or compiling a static site.
