A computer implemented method optimizes a configuration of an information technology (IT) infrastructure. A processor establishes a technology rule set, which defines technology weights of an IT infrastructure by mapping capabilities of IT infrastructure components to IT infrastructure attributes needed to execute a specific workload. A candidate IT infrastructure for executing the specific workload is then configured. The processor then receives responses, provided by a customer, to an attribute questionnaire. Each question in the attribute questionnaire is mapped to an IT infrastructure attribute of the candidate IT infrastructure, and the responses define a customer's level of agreement/disagreement with the technology weights. In response to the processor determining that the candidate IT infrastructure fails to meet the customer's expectations, the candidate IT infrastructure is reconfigured until the customer's expectations are met.
