Run a Mathematica program in a cluster

Question

Suppose I want to run a Mathematica program that I wrote, in a cluster or using a cloud computing solution. Can Mathematica programs run on their own without a license? And in case they don't, do cloud-computing solutions come packaged with the resources to do it?
