What does the term "scalability" refer to in cloud computing?

Scalability in cloud computing specifically refers to the capability of a system to adjust its resources to accommodate varying workloads. This means that as the demand for services increases, a scalable cloud infrastructure can provision additional resources, such as processing power, memory, or storage. Conversely, when demand decreases, resources can be scaled back to avoid unnecessary costs. This on-demand adjustment is a fundamental advantage of cloud computing, allowing organizations to efficiently manage resources according to their current needs, ensuring performance and cost-effectiveness.

In the context of the other choices, storing data securely, integrating multiple services, and maintaining data integrity are essential components of cloud services, but they do not encapsulate the concept of scalability. Scalability is uniquely about resource management in relation to changing demand.
