None of our services requires specific cloud platforms. We use no proprietary cloud APIs. This means our services can run on any cloud; the only requirement is that we can spin up a Linux machine on it. As far as we know this is something absolutely all cloud platforms offer.
We are currently running our servers on Digital Ocean (Linux Servers) and Azure (Microsoft Windows Servers).
The only exception for being “cloud agnostics” would be services that our customers typically depend on. Currently, we are doing work to support Single-Sign Ons (SSO) through Active Directory services from Microsoft’s Azure cloud.
