Cloud bursting is a technique that allows you to automatically scale your cloud resources up or down based on demand. This can be a cost-effective way to address spikes in traffic or workload, without having to invest in additional hardware.
In this case, the company can configure cloud bursting to automatically spin up new VMs in the public cloud when the private cloud reaches its capacity. The new VMs will be terminated when the usage is back to normal. This will allow the company to handle the increased traffic without having to invest in additional hardware.
