@souenzzo OMG. Zookeeper, too? (Programming) life just is not that simple any more.

Which AWS EC2 instance size should I use for Datomic transactor? The cloudformation templates still have c3.large, which seems to be no longer available (maybe just hidden)

This is for testing/staging loads. Will t2.micro / t2.small do?
