Would you be installing your databases on the same tier (same VM's) as the app server? If so, and you went with multiple instances of Tomcat per VM, would you be using multiple running instances of MySQL or multiple schemas within the same database instance? Personally I don't like running multiple production applications on a single VM, especially when they're mission-critical, because it limits how quickly you can respond to change. Although retail providers of VM's don't often have a cost model that reflects it, the additional hardware utilization by having multiple small VM's vs. fewer large VM's is negligible in light of the scalability and redundancy benefits it offers, IMHO. Either way you would have some disk space and memory constraints for the database that you forgot to mention (at least in this thread).
