A private cloud customer is considering using the public cloud to accommodate the peak utilization workload. Which of the following would be considered the ideal scaling solution?

Cloud bursting allows an organization to run workloads in a private cloud and automatically extend into public cloud resources when on-premises capacity is insufficient to meet peak demand. This provides cost-effective elasticity without permanently provisioning expensive private cloud infrastructure for workloads that only spike periodically.

Load balancing distributes incoming traffic across existing servers to optimize utilization but does not extend capacity into a public cloud environment during peak load.

Horizontal scaling adds more instances of a resource within the existing environment but does not describe the specific mechanism of extending from private to public cloud infrastructure.

Vertical scaling increases compute resources such as CPU and RAM of existing instances within the current environment and does not address leveraging public cloud capacity for overflow workloads.
