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?

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?

• A. Cloud bursting
• B. Load balancing
• C. Horizontal scaling
• D. Vertical scaling

Answer: (A)

The main idea being tested is using cloud bursting to handle peak workloads in a hybrid cloud setup. Cloud bursting lets your baseline work run in the private cloud, but automatically spill over excess demand into the public cloud when utilization spikes. This lets you meet peak performance without permanently expanding on-prem capacity, paying for the public cloud resources only during those spikes. This approach is the best fit because it directly leverages the public cloud for temporary increases in capacity, preserving private-cloud control and cost efficiency for normal operation. In contrast, simply load balancing spreads work among current resources and doesn’t inherently increase overall capacity with public cloud, while horizontal scaling adds more servers within the same environment and vertical scaling increases power of existing servers—neither by itself provides seamless, on-demand use of public cloud resources for peak traffic.
