Multi-Region Kubernetes at Scale: Lessons from Running Rancher and RKE2 in Production

Operating persistent workloads across globally distributed Kubernetes clusters is hard.

This talk dives into a realworld implementation of a "cluster of clusters" architecture built using opensource tools like Rancher, RKE2 and Helm

We will discuss -

• Designing a “cluster of clusters” model with Rancher acting as a gcp(global control plane)

• Simplifying operations with GitOps-driven templates and centralized policy management.

• Configuring secure inter-cluster communication with VPC peering and VPN tunnels.

• Automating cluster onboarding, upgrades and rollbacks with minimal downtime.

• Addressing challenges like cross-region latency, HA configuration and team level access control.

practical takeaways for

• DevOps engineers

• SREs

• platform teams

• anyone building or operating distributed Kubernetes infrastructure.

  this talk is particularly relevant for those working with stateful applications, storage, or looking to scale infrastructure in a maintainable, secure way using open-source components.

  How do big cloud service providers manage their storage-apps and provide 5 9 SLAs at scale? - this is the biggest take away from this talk!
