The Hosting API makes it possible to define a ``Virtual'' Hosting
service. Such a service aggregates the services provided by one or
more other Hosting Services. This has the following advantages for
an application:
- The application can be migrated between real hosting services, or
spread across services from one or more providers.
- The creator of the virtual hosting service can issue multiple hosting
contracts for the virtual service, keeping different components of
an application separate. Only one contract is required from the provider
of a real Hosting Service.
The Hosting API's are designed to make this aggregation possible.
