1. A method, comprising: provisioning, by a processing device, a first load generation unit in a cloud computing environment; instructing the first load generation unit to generate a first load and apply the first load to a first application server instance in the cloud computing environment, wherein the first load comprises a Hypertext Transfer Protocol (HTTP) request; measuring a performance level of the first application server instance to determine when the first application server instance reaches a saturation point; when the first application server instance reaches the saturation point, recording a performance statistic of the first application server instance, the performance statistic comprising a time between the first application server instance reaching the saturation point and when a second application server instance is provisioned in the cloud computing environment in response to the first application server instance reaching the saturation point; and when the first application server instance does not reach the saturation point, provisioning a second load generation unit and instructing the second load generation unit to generate a second load and apply the second load to the first application server instance while the first load generation unit continues to apply the first load to the first application server instance.
