IBM ODM on Cloud is a subscription based offering that provides a complete IBM ODM service in the cloud. Compared to the traditional software license model (where you buy licenses, install the software somewhere, and administer it), ODM on Cloud is a more turnkey solution. IBM runs the environment, so you can focus on delivering ODM decision services.
Software-wise, ODM on Cloud is the same as ODM. You use the same tools, build the same artifacts, etc.
Here are a few demos of the ODM on Cloud solution.
