Hi, author here. We support a diversity of different hosting providers (Google, Azure, DigitalOcean, AWS), including your own self-hosted server. It's an install script, we don't pick the host for you, that's your decision.
You can start up a machine on either of those providers and then run the install scripts locally. Plenty of people have done it. Note: this is the same answer for every hosting provider, as long as they support Ubuntu 16.04 or 17.04.
