1. A computer implemented method of optimizing a configuration of an information technology (IT) infrastructure, the computer implemented method comprising: a processor establishing a technology rule set, wherein the technology rule set defines technology weights of an IT infrastructure by mapping capabilities of IT infrastructure components to IT infrastructure attributes needed to execute a specific workload; the processor configuring a candidate IT infrastructure for executing the specific workload; the processor receiving responses, provided by a customer, to an attribute questionnaire, wherein the responses define a customer's level of agreement with the technology weights, wherein each question in the attribute questionnaire is mapped to an IT infrastructure attribute of the candidate IT infrastructure, and wherein the IT infrastructure attribute comprises an attribute from a group consisting of an enablement of increased IT integration by use of the candidate IT infrastructure over the current IT infrastructure, a reduction in a level of disruption caused by power failures by use of the candidate IT infrastructure over the current IT infrastructure, a reduction in incidences of operator errors by use of the candidate IT infrastructure over the current IT infrastructure, and a reduction in tasks associated with the specific workload by use of the candidate IT infrastructure over the current IT infrastructure; and in response to the processor determining that the candidate IT infrastructure fails to meet a customer's expectations, of the customer, for an IT infrastructure's performance abilities, reconfiguring the candidate IT infrastructure until the customer's expectations are met.
