Which provides services with a single purpose or function?

• A. Enterprise Service Bus
• B. Data Creation
• C. Service-Oriented Architecture
• D. Content Management System

Answer: (C)

In a Service-Oriented Architecture, functionality is broken into discrete services, each designed to perform a single, well-defined function. Each service exposes a stable interface or contract that other parts of the system can call, often over a network, enabling easy reuse across different applications. This single-purpose design makes it straightforward to compose complex capabilities by combining multiple services, and it allows individual services to be updated or replaced without disrupting others.

An Enterprise Service Bus is a communication backbone that connects and routes messages between services, rather than defining a single-purpose service itself. A Content Management System handles organizing and delivering content, not the architectural approach of splitting functionality into dedicated services. Data creation isn’t an architectural pattern for providing services.
