The advantage of such a hybrid cloud deployment is that an organization only pays for extra compute resources only when they are needed.

The Business Impact of Cloud Bursting

The line at the top shows the associated costs for provisioning all the resources for peak loads. The blue lines show what the cost could be if they’d provision for the average load and use on-demand resources for the peak loads. Based on this case study, cloud bursting can yield a 40% reduction in overall costs.
