What describes the fundamental change in how businesses manage IT resources through cloud computing?

The fundamental change in how businesses manage IT resources through cloud computing is best described by dynamic resource management. This concept refers to the ability to automatically allocate, scale, and manage resources based on current demand, rather than relying on fixed, static resources. In a cloud environment, businesses can quickly adjust their resource usage in response to changing needs, optimizing efficiency and cost.

Dynamic resource management allows organizations to provision and de-provision resources in real-time, leading to greater flexibility and responsiveness. This shift from traditional IT management, which often involved significant upfront investment and a slower response to changes in workload, has transformed how businesses operate. By leveraging cloud computing, companies can achieve better utilization of their IT resources, ensuring they're only using what they need when they need it, which enhances performance and reduces costs.
