Ensuring resilience in control planes is critical for organizations managing infrastructure and applications across multiple regions with Kubernetes. This talk presents a reference architecture for creating a Crossplane-based Global Control Plane, enhanced with k8gb for DNS-based failover and leveraging an Active/Passive setup.
We’ll explore how Crossplane’s declarative infrastructure provisioning integrates with k8gb to build robust, scalable, and resilient multicluster environments. Key takeaways include:

- Architecting resilient multiregion control planes with Active/Passive roles
- Demonstrating failover mechanisms where the Passive control plane transitions to Active during failures
- Strategies for optimizing failover times while maintaining availability

This session will guide attendees through proven methods and real-world challenges of building resilient Global Control Planes, empowering them to manage critical workloads across geographically distributed regions confidently.
