Typical infrastructure services may, for example, include messaging, storage, naming, and directory services. It may access artifacts; e.g., a file containing a message.

The name of an infrastructure service should preferably be a verb ending with “‑ing”; e.g., “messaging”. Also, a name explicitly containing the word “service” may be used.
