You can run grails in 256 megabytes. Many community members do this. That being said, I would say that on any platform you want a lot more sheep than to make sure your performer. But I can also recommend checking out www.linode.com. You can get high-quality hosting at a very reasonable price, and adding a little bar for the grail will not violate your budget. Also, if you are interested in cloud solutions, Morph offers Grails applications.
