Which design principle of secure cloud computing ensures that users can utilize data and applications from around the globe?

The design principle that ensures users can utilize data and applications from around the globe is broad network access. This principle is fundamental to cloud computing as it allows users to access cloud services over the internet from various devices and locations without being restricted to specific hardware or network configurations.

Broad network access means that cloud services are available not just within a localized network but are accessible through the internet, enabling users to connect to their applications and data from anywhere in the world. This flexibility is crucial for businesses and individuals who require mobility and the ability to collaborate across different geographical locations.

The other principles, while important, focus on different aspects of cloud computing. For instance, portability refers to the ease with which applications and data can be transferred between different cloud environments, scalability is about the ability to adjust resources based on demand, and on-demand self-service allows users to provision computing resources without requiring human intervention. These aspects contribute to the overall functionality and user experience of cloud services but do not specifically address global accessibility in the same way that broad network access does.
