Dynamic scaling is a term that refers to the automated management of cloud resources that can adjust based on current demand. This approach allows systems to automatically increase or decrease resources, such as computing power or storage, in response to fluctuations in workload. For instance, during peak usage times, additional servers may be provisioned to handle the increased load, and conversely, resources can be scaled back during lower usage periods. This ability to adapt resources in real-time ensures optimal performance and cost efficiency.

In contrast, static scaling involves setting a fixed amount of resources regardless of demand, which can lead to either underutilization or insufficient capacity during high demand. Load balancing, while related to distributing workloads evenly across resources, does not inherently involve the automatic adjustment of the resource quantity itself. Provisioning refers to the process of allocating resources but does not specifically denote any automated response to changing demand. Therefore, dynamic scaling is the most accurate term for automated resource management based on demand in a cloud environment.
