(*) Corrected, see note below. Definition: Computing Hosting, Networking, and Data Hosting Infrastructure ABB are a Technology Service that enables the functionalities for i) hosting Interoperable European Solutions and ii) providing the necessary networks for operating these solutions.

Hosting and networking represent the lower level of the technical layer, but to be considered when designing an interoperable solution, as they can create interoperability barriers. Interoperability technical specifications need to be used at this level to ensure interoperability of the levels above.
