Foreign components as Adapters

Source: APPUiO Cloud administrator
Stimulus: Desire to integrate a third-party component
Environment: APPUiO Control API
Artifact: Third-party component
Response: New third-party component works transparently with APPUiO Control API.
Response measure: Third-party system behaves according to the API specification (see Design by contract principle applied to components)
Rationale: The APPUiO Control API should ensure replaceability for parts of functionalities so that the foreign component can be integrated. For example an ERP responsible for invoices can be integrated or replaced so that the functionality of APPUiO Cloud is complete.
