Bayer Business Services, the Bayer Group’s global competence center for IT and business services, was looking for a way to reduce costs while maintaining the quality of its mission- critical SAP infrastructure. Bayer chose to migrate from AIX, a proprietary UNIX operating system, to Red Hat® Enterprise Linux® and substituted IBM servers running on proprietary software with standards-based x86-servers. With this dual solution approach, Bayer Business Services improved performance at a much lower total cost of ownership (TCO).
