Which feature distinguishes traditional systems development from modern approaches?

The correct choice highlights the incorporation of cloud-based environments as a distinguishing feature of modern systems development compared to traditional approaches. Traditional systems development often relied on on-premises applications and infrastructure that required significant hardware investment and management within an organization. These systems typically operated in isolation, which could limit scalability and flexibility.

In contrast, modern approaches leverage cloud computing, which enables scalable solutions, easier collaboration, and access to resources from anywhere with an internet connection. Cloud environments facilitate the use of services and storage that can dynamically adjust based on the system's needs, supporting the rapid deployment of applications and the ability to handle large amounts of data seamlessly. This shift also supports more collaborative development methodologies, such as agile, which thrive on rapid iterations and frequent updates, further underscoring the modern paradigm in system development.

While agile methodologies, desktop applications, and single-user applications do play roles in different contexts of systems development, they do not capture the transformative impact and broader implications of cloud technology on the development practices themselves. Thus, the incorporation of cloud-based environments serves as a key differentiator between traditional and modern systems development approaches.
