What advantage does cloud computing offer over traditional on-premises solutions, particularly regarding resource scalability?

1. Static resource allocation

2. Global scalability

3. Local scalability only

4. Hardware dependency

The correct answer is: Global scalability

Choosing global scalability as the advantage of cloud computing over traditional on-premises solutions highlights one of the most significant benefits that cloud environments provide. In a cloud computing setup, resources—such as storage, computing power, and applications—can be dynamically scaled up or down based on demand across diverse geographical locations. This means that organizations can deploy resources in multiple regions instantly, responding to user needs and traffic changes without being limited by local capabilities or hardware limitations. With global scalability, businesses can improve performance for end-users by placing resources closer to them, ensuring faster access and lower latency. This level of flexibility and reach is difficult to achieve with on-premises solutions, which are typically confined to a specific physical location and require significant investment and time to scale up resources. The cloud allows organizations to pay for only what they use, which makes it an economically attractive option, especially during varying workloads. In contrast, static resource allocation, local scalability, and hardware dependency reflect constraints that typically accompany traditional infrastructure. Static resource allocation does not allow for flexibility in resource usage, which can lead to wasted capacity or shortages. Local scalability only addresses resource needs within a specific location, lacking the expansive adaptability of global scalability. Hardware dependency negates the inherent benefits of cloud computing, as organizations would
