Final answer:
A service broker is a specific kind of service provider that acts as a registry and allows for the lookup of service provider interfaces and service locations. Option D is correct.
Step-by-step explanation:
A service broker is a specific kind of service provider that acts as a registry and allows for the lookup of service provider interfaces and service locations. It acts as an intermediary between service requestors and service providers, facilitating the discovery and connection of services.
The service broker maintains a registry of available services and assists in matching service requestors with suitable service providers.
For example, in a distributed system architecture, where different components communicate and interact with each other through services, a service broker can help manage the discovery and connection process. It provides a central point where services can be registered and looked up, making it easier for different components to locate and utilize the services they need.
The answer to the question is D) Service broker. A service broker is a specific kind of service provider that functions as a registry. It allows clients to look up service provider interfaces and service locations in a service-oriented architecture (SOA).
This supports the dynamic discovery and binding of services at runtime, which is essential for building flexible and scalable software systems. When a service requestor searches for a specific service, the service broker plays the key role in directing the requestor to the appropriate service provider.
Service brokers also facilitate loose coupling between service requestors and providers, which is a fundamental principle in SOA.
