Sure are! On the home page ( https://coreos.com ) you'll find links to directions for various providers from EC2 & Rackspace to OpenStack & Vagrant. Each has the exact directions that will get you started with least effort (including image ids where appropriate and URLs otherwise).
It would be great on one machine. First, it's a lightweight host for docker containers, like less than half the size, so you can do more with that single machine.
Second, if it ever turns out you _need_ a second machine, you have room to grow, other than just getting a bigger box.
I am really surprised as CoreOS is super new to a lot of people and yet they managed to convince Google and Amazon to provide an image. That's amazing...
