SAP applications, such as Treasury and Risk Management, SAP ERP, SAP BW, or SAP HCM, are the very core of a company. For its SAP applications, ZEISS had opted for an on-premises setup—an outdated and less flexible solution that was difficult to operate and modernize. This led to lengthy and slow processes in IT, and the automation of recurring processes seemed virtually impossible. Then, in 2017, the company made a decision: it would migrate business-critical SAP applications to the Microsoft Cloud with the help of Azure. ZEISS now benefits from unlimited scalability, flexibility, automation, and high speed in application development and use.
