Is it possible to choose the operating system of my server with ScalaHosting?
ScalaHosting's shared and managed VPS servers all come with CentOS, but with a self-managed VPS or a dedicated server, you have a choice. If you go for an unmanaged VPS, you can choose from CentOS, Ubuntu, Debian, openSUSE, and Windows, and for your dedicated server, you can pick between CentOS and Windows.
