In the context of the fourth industrial revolution, an increasing number of advances in manufacturing result from smart integration of information technology (IT) and data-driven solutions in factories. An essential limiting factor for improvements is the capability of the IT system. In addition to the IT hardware specifications, the choice of an appropriate IT architecture (Cloud, Fog, or Edge Computing driven) determines the overall investment, environmental impact, and resulting net benefit. This article presents a comprehensive systematic approach that seeks to support the choice of an appropriate IT infrastructure. It is deliberately aimed at supporting especially non-IT experts, guiding the practitioner through a multi-phase process. The approach is applied to an exemplary use case in the field of industrial technical building equipment, but can also be applied to any application case involving the planning of the IT infrastructure in a manufacturing context. The results illustrate the applicability and the potential of appropriately selecting a suitable IT infrastructure.

在第四次工业革命的背景下，制造业中越来越多的进步来自工厂中信息技术（IT）和数据驱动解决方案的智能集成。改进的基本限制因素是IT系统的功能。除了IT硬件规范之外，是否选择合适的IT体系结构（由云，雾或边缘计算驱动）决定了总体投资，环境影响以及最终的净收益。本文提供了一种全面的系统方法，旨在支持选择合适的IT基础架构。它的目的是特别为非IT专家提供支持，通过多阶段过程指导从业人员。该方法适用于工业技术建筑设备领域的示例用例，但也可以应用于涉及制造环境中IT基础架构规划的任何应用案例。的结果说明的适用性和适当地选择合适的IT基础设施的潜力。
