One or more computers receive a request from a user to change a configuration of a computing environment provided by one or more servers. In response to receiving the request and before performing the requested change in the configuration of the environment, the computers determine an estimated measure of performance that represents a level of performance of the computing environment if changed according to the request and provide data indicating performance measures indicating the estimated measure of performance for the environment corresponding to the change in the configuration of the environment. After providing the data indicating the estimated performance measures, the computers receive data indicating user input confirming the request to change the configuration of the environment, and perform the requested change in the configuration of the computing environment.
