Rapid testing of configuration changes in software defined infrastructure

A computer usable program product comprising a computer-readable storage device, and program instructions stored on the storage device, the stored program instructions comprising:

• program instructions to forecast, by analyzing operational data from a production software defined infrastructure (SDI), a future event that is likely to occur in the production SDI at a future time;
• program instructions to forecast, using a repository of correlation records, a set of configurations that are likely to change in response to the future event;
• program instructions to construct, corresponding to a configuration from the forecasted set of configurations, an instruction for a testing SDI;
• and
• program instructions to cause, responsive to the instruction, the testing SDI to initialize a test virtual machine (VM) in the testing SDI, wherein the test VM is specifically configured to test a change in the configuration from the forecasted set of configurations, and wherein the test VM is ready to test the change when the future event occurs at the future time.

A computer system comprising a processor, a computer-readable memory, and a computer-readable storage device, and program instructions stored on the storage device for execution by the processor via the memory, the stored program instructions comprising:
