System Architecture vs System Design

System architecture and system design are two related but distinct concepts in the field of software engineering.

System architecture refers to the overall high-level design of a software system, including its components, structure, and interactions. It defines the fundamental principles and guidelines that govern the system’s construction and operation. System architecture often involves decisions regarding the selection of hardware and software components, as well as the protocols and standards for communication and data exchange between them.

System design, on the other hand, is the process of defining the detailed specifications of the software system based on the overall architecture. It involves the creation of detailed design documents, diagrams, and other artifacts that specify the implementation details of the system’s components and their interactions. System design is typically focused on the implementation of the system’s functionality, performance, and usability requirements.

In summary, system architecture defines the high-level structure and principles of a software system, while system design involves specifying the details of the system’s implementation based on the architecture. Both of these concepts are critical to the successful development of complex software systems that meet the requirements of their stakeholders.
