Together with T-Systems, Gerresheimer AG analyzed the situation and went through various scenarios. This revealed that a complete migration of the systems to the Azure Cloud would not be the ideal target scenario. Based on the application needs as well as consideration of privacy aspects, the partners developed a multi-/hybrid cloud concept for the future Gerresheimer IT landscape. It turned out that the Future Cloud Infrastructure (FCI), a modern private cloud solution from T-Systems, would offer great advantages in the migration process. Since most of the IT systems are based on VMware technology (as is the FCI), they could be migrated completely in “as is” status to the FCI. This meant Gerresheimer was able to rapidly achieve its primary goal of platform consolidation and enhanced operating efficiency.
The room for maneuver gained allowed those responsible at Gerresheimer together with the T-Systems experts to make a detailed analysis of the application landscape and develop an optimized target vision. As part of the cloud migration framework, the partners envisioned different target scenarios for the servers – depending on the technical and privacy needs of the applications. Some would remain in their current state, while others would be migrated to new platforms: Systems with high dynamism and need for innovation move as before into the Azure Cloud. There they are administered in a standardized landing zone by T-Systems. This landing zone also features state-of-art security. Systems with lower dynamism, which continue to be operated on VMware, remain on the FCI. There they are managed either in-house or by T-Systems – depending on how relevant direct access to the platform and the application is for Gerresheimer.
