So I've opened their AWS replacement website (Outscale), Computing page.
No dedicated servers (VM only). Ok let's check VM price https://en.outscale.com/customized-virtual-machines/
Press the "Do you have a Cloud Project?" which is the only button? Oops! Something went wrong here.
Is this supposed to be an AWS replacement?
Outscale is kind of the stereotypical bureaucratic French thing. It's made by Dassault, that's better known for industrial stuff (like SolidWorks), not for modern-ish software.
For a more of an AWS replacement, look at Scaleway. It really is more what we think about when talking "public cloud": self-serve compute, with lots of managed services, actual API and Terraform, actual K8s, etc. (managed services is why I don't mention OVH, which is often touted as a "cloud provider", yet lacks a large managed services offering).
