Tjenesteudsender

Tjenesteudsender is a Danish term describing the component, role or device that distributes or makes a service available to consumers or other services. It is not a fixed product category but a functional description used in information technology and telecommunications to denote the part of a system that performs service delivery.

A tjenesteudsender typically handles tasks such as exposing service interfaces (for example REST, SOAP or gRPC), routing requests to appropriate service implementations, and mediating security checks, monitoring, logging and throttling. In event-driven architectures it may act as a publisher in a publish-subscribe pattern, disseminating messages to subscribers or to other services via a service bus or message broker. In API and cloud contexts it is often realized as an API gateway, a service proxy, or a distribution node.

The term can apply across contexts, including microservices, enterprise integration, public digital services, and telecommunications networks. It is usually distinguished from the service provider (tjenesteudbyder), which creates or owns the service, and from the consumer who uses the service. The tjenesteudsender therefore focuses on making the service accessible, reliable, and controllable in terms of access and performance.

Examples include an API gateway that accepts external requests and forwards them to internal services, or a message broker that publishes events to multiple subscribers. In practice the exact implementation varies with architecture, protocols, and organizational needs.
