Major Reinsurer Migrates SAP to the Cloud for Operational Resilience
Swiss Re, one of the world’s largest reinsurers, migrated its SAP S/4HANA systems from a hosted private cloud to Microsoft Azure as part of their broader IT modernisation initiative. Prior to this transformation, the incumbent environment suffered from low availability and limited agility, which affected infrastructure resilience and resulted in recurrent component failures. By moving to the Azure public cloud, Swiss Re sought to boost efficiency, optimise capital investment, and reduce operating costs. This migration enabled rapid prototyping of enterprise application features, higher application availability, and paved the way for better scalability in supporting business growth. The enhanced agility also allowed Swiss Re to respond more rapidly to internal demands and changes in the reinsurance landscape, building a technology foundation for subsequent innovation.
