HanseMerkur is one of the oldest private health insurance companies in Germany. The company ran multi-tenant clusters on premises with Kubespray, with a legacy platform based on Kubernetes 1.11 (released in 2018).
This setup resulted in several operational problems, including high overhead and over-consumption of hardware. Because of this, HanseMerkur’s platform team wanted to go bare metal and consolidate HanseMerkur’s entire infrastructure into one place.
The consolidation project required HanseMerkur to solve three major challenges with their Kubernetes operations.
- Maintenance overhead and lack of workload isolation for compliance
- Long approval cycles for platform and security teams
- Lack of visibility for dev teams
