I assumed it mean representing various infrastructure (load balancers, http servers, microservices, databases, etc and their interconnections) as resources that you can add relations to in a code description and then it could resolve those as code, if you add new resources (code), it can work out dependencies and therefore help coordinate and make sure you don't overlook some critical link (like version compatibility) as developers add to it. It seems to have provisioning for CI as well.
