What is cloud bursting?

An application model that remains exclusively in a private cloud
An application model that allows burst capacity to a public cloud
An application model that uses only public cloud services
An application model that limits storage options

The correct answer is: An application model that allows burst capacity to a public cloud

Cloud bursting is a specific approach to cloud computing that enables an application to handle increased demand by leveraging additional resources from a public cloud. This model is particularly useful for applications that experience variable workloads, allowing them to operate primarily in a private cloud while "bursting" into a public cloud when necessary. In this scenario, if the private cloud runs out of resources or cannot accommodate spikes in demand, the application can seamlessly access extra capacity from the public cloud. This flexibility not only helps manage costs effectively—since organizations only pay for the extra resources when they are needed—but also ensures that service levels are maintained during peak times. This ability to scale resources dynamically makes cloud bursting a modern and efficient strategy for managing cloud resources, particularly in environments with fluctuating workloads. The other options do not align with this definition, as they describe different cloud models or restrictions rather than the hybrid nature of cloud bursting.
