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

The principle of broad network access is fundamental in secure cloud computing as it ensures that users can access data and applications from any location with internet connectivity. This characteristic is especially important in a globalized environment, as it promotes flexibility and convenience for users who may need to work from different geographical locations.

Broad network access allows users to connect to cloud services through various networks, including mobile networks, Wi-Fi, and other internet service providers. This feature not only promotes collaboration among users by enabling them to share resources and tools no matter where they are located but also supports the principle of user accessibility and inclusivity in leveraging cloud technologies.

While portability refers to the ability to move applications and data between cloud services, and scalability involves the cloud's capacity to adjust resources based on demand, neither directly addresses the global accessibility aspect as effectively as broad network access does. On-demand self-service relates to the ability for users to provision resources as needed without requiring human intervention. Although all these principles contribute to the overall security and efficiency of cloud computing, broad network access specifically highlights the usability of cloud resources from various locations globally.
