Facade Service

A facade service is any application service or API that the gateway offers. Typically the service is an intermediary to one (or more) target services outside the gateway.

A facade service may also be known as a proxy service or virtual service, especially if the interface of the facade and target services are the same. The gateway facilitates a loose coupling between the facade and target service by managing interfaces, policies and configuration information for either the facade service or target service.

Policies applied to a facade service are enforced by the gateway and include decryption, validation, throttling, and authorization.
