As others have said, similar to DO. It has a few more options available, though, including better support for booting your own OSes if you don't want to use a prepackaged one, and dedicated instances (last I checked DO didn't do either, but haven't looked for a bit, might be out of date). I've also found their support to be more willing to work with me to get things running how I want, but that's obviously just anecdotal.
