Case Study: HanseMerkur reduces infrastructure overhead and achieves compliance with Tigera Calico

HanseMerkur consolidates 16 clusters into 4 with Tigera

HanseMerkur, one of Germany's oldest private health insurance companies, faced significant operational challenges with its multi-tenant on-premises Kubernetes clusters. The legacy setup resulted in high infrastructure overhead, hardware over-consumption, and a lack of workload isolation necessary for organizational compliance. To consolidate its infrastructure, HanseMerkur needed to solve issues with maintenance, long security approval cycles, and a lack of visibility for development teams.

Tigera's Calico provided the solution by enabling the enforcement of microsegmentation and delivering the required security and observability capabilities. This allowed HanseMerkur to move to a bare metal infrastructure and consolidate 16 clusters into just 4. The implementation by Tigera successfully reduced infrastructure overhead and ensured the company remained compliant with all regulatory requirements.
