The definition of
underlying infrastructure in the context of the question relates to the fabric that supports the services rendered for a given collection of systems such as example cabling, power, cooling, etc.
Currently it isn't clear if the project is responsible for defining these or simply subscribes to existing capabilities. For example, if a given system is deployed that requires a certain amount of power, does the project simply communicate this or does it need to expand on existing requirements.
The scope of the project thus far has been to deliver the system.
