The role of software architecture involves designing the structure and organization of software systems. It encompasses defining components, their interactions, and guidelines for development, ensuring that various software parts work cohesively. A well-considered architecture addresses non-functional requirements such as scalability, performance, and security while facilitating future maintenance and adaptability. Software architects collaborate with stakeholders, translating business needs into technical specifications and making critical decisions that impact the overall system design. Effective software architecture ultimately contributes to the long-term success and quality of software applications.
