Various projects and organizations who work with cloud computing use different words to refer to the same thing. This cross-reference shows the words used by Exosphere. In most cases, Exosphere has adopted the OpenStack term, except where a clearer/better term exists for the target audience (researchers and other non-IT professionals).
Note for users: an organization can offer a customized version of Exosphere with localized nomenclature (see localization section of README.md), so if you are using Exosphere somewhere other than try.exosphere.app, that interface may use different words. Ask your administrator for details.
Note for developers: some code in the Exosphere codebase (e.g. variable and function names) may use OpenStack terms instead of the "Exosphere new default term" listed below. Please see issue 506 for ongoing work to resolve this.
