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 is a hybrid cloud strategy where an application primarily runs in a private cloud and seamlessly extends into a public cloud to handle spikes in demand, effectively accommodating peak utilization workloads without over-provisioning private infrastructure.

Load balancing distributes incoming traffic across multiple resources within a system to optimize resource utilization and maximize throughput, but it does not inherently involve extending capacity to a separate cloud.

Horizontal scaling (scaling out) involves adding more instances of resources, typically servers or virtual machines, within a given environment, but it does not specifically refer to extending from a private to a public cloud.

Vertical scaling (scaling up) involves increasing the resources (e.g., CPU, RAM) of an existing single instance or server, which has inherent limits and does not involve leveraging the public cloud.
