What is the primary focus of Service Oriented Architecture (SOA)?

The primary focus of Service Oriented Architecture (SOA) is on combining and coordinating services. SOA is an architectural pattern that allows for the software components to communicate and work together as interoperable services regardless of their underlying platforms or languages. This approach promotes reusability, scalability, and flexibility as services can easily be combined in different ways to achieve various business processes and functionality.

The essence of SOA lies in its ability to facilitate communication between loosely coupled services, which can be independently developed and deployed. This allows organizations to adapt more readily to changing business requirements and promotes efficient integration between disparate systems.

In contrast, the other options do not capture the core principles of SOA. Network management and monitoring primarily focus on managing the network infrastructure rather than the architectural principles of service integration. Data storage and retrieval processes are more aligned with database management and data architecture, not the integration of services. User interface design is concerned with the visual aspect of applications and how users interact with software, which also falls outside the main focus of SOA.
