What aspect of systems design allows for building across multiple uses, viewpoints, and structures?

Scalability is a core aspect of systems design that refers to the ability of a system to accommodate growth or changes in workload. When a system is designed with scalability in mind, it means that it can be adapted to handle a higher volume of users, data, or transactions without requiring a complete redesign. This is particularly important as software and systems often need to evolve over time to meet increasing demands or to integrate new functionalities.

Building for scalability encourages the use of modular architectures or solutions that can expand or contract according to varying requirements. For instance, cloud computing is a prime example of a scalable solution, where resources can be dynamically allocated or released based on usage.

By focusing on scalability, designers can create systems that are flexible and resilient, allowing for multiple uses, viewpoints, and structures to coexist and thrive within the same framework. This ensures that an application can remain effective as user needs change or as new features are integrated, keeping the user experience seamless and consistent.
