I want to be very clear that there are definitely other good choices for your domain and hosting out there. This is simply the one I’ve been using since the beginning, and I’m very satisfied.

Alternatively, you can set up your own virtual machine, but that takes some expertise. (If you're going that route, Microsoft has some tools for developers including a ready-to-use virtual machine at modern.ie.) how to build a website
