Cloud bursting is a deployment model where applications normally run in a private cloud or local data center. During peak loads, when the resources and computing power of the private cloud or data center are no longer sufficient, cloud bursting additionally accesses the resources of the public cloud. This results in a hybrid operation with two clouds.
Cloud bursting has the advantage that additional computing power from the public cloud only needs to be requested and paid for when required. In addition, the computing power is available at short notice. In cloud bursting, the private cloud and the publich cloud operate as a hybrid cloud.
Cloud bursting can be usefully employed if the company's own data center does not require any additional computing power during normal operation. It is particularly suitable for low- sensitivity applications and those that do not affect corporate security.
