Which design pattern describes software components that expose specific functionality as services to other applications?

Which design pattern describes software components that expose specific functionality as services to other applications?

• A. Monolithic Architecture
• B. Microservices Architecture
• C. Service Oriented Architecture (SOA)
• D. Model-Driven Architecture

Answer: (C)

The concept here is exposing capabilities as reusable services that other applications can consume. That is the hallmark of Service Oriented Architecture. In SOA, components are designed as services with well-defined interfaces and service contracts, enabling different applications to discover and interact with them over a network using standard communication protocols. This loose coupling and cross-application interoperability are what set SOA apart. Monolithic architecture bundles everything into one deployable unit, so there aren’t discrete services exposed to other apps. Microservices also expose services, but the defining focus of SOA is the broader, contract-driven service-oriented integration across diverse applications. Model-Driven Architecture centers on modeling and generating code from models, not primarily on exposing services.
