Resources are Services (Workflows) or microservices and Data Connectors (Stored Procedures, Web Services, DLLs and their respective Sources).
Services are created by mashing up tools and other resources. We do this by constructing workflows on the design surface. They can be finely-grained and micro or very complex and extensive.
Data Connectors allow us to connect to different technologies as part of a service. This framework is continuously being added to.
