A method may include validating an execution plan specifying one or more configurations to apply to an information technology infrastructure. The execution plan may be validated by at least determining a structural validity of the configurations of the execution plan. In response to the configurations of the execution plan being determined to be structurally valid, the validation of the execution plan may further include determining whether the information technology infrastructure satisfies a policy if the configurations specified in the execution plan are applied to the information technology infrastructure. In response to a successful validation of the execution plan, the one or more configurations specified in the execution plan may be applied to the information technology infrastructure by at least provisioning, modifying, and/or de-provisioning one or more resources at the information technology infrastructure.
