Which term describes a technique where applications run in a private cloud and burst to a public cloud during peak demand?

The term that accurately describes the technique where applications primarily operate in a private cloud but extend to a public cloud during periods of peak demand is cloud bursting. This approach allows organizations to leverage the reliability and security of a private cloud while also taking advantage of the scalability and additional resources offered by public cloud services.

Cloud bursting is particularly beneficial for handling sudden spikes in workload or demand that may exceed the capacity of the private cloud. By seamlessly integrating both environments, businesses can optimize resource allocation and control costs, ensuring they only pay for the additional resources when necessary. This model exemplifies efficient cloud utilization and flexibility in resource management.

In contrast, other terms like cloud mirroring refer to creating a backup of data on another cloud, hybrid clouding generally describes a combination of cloud environments without the specific bursting aspect, and cloud scaling pertains to adjusting resources either up or down in response to demand, but not necessarily involving both private and public cloud resources in the way cloud bursting does.
