Managing multiple Kubernetes clusters across different cloud providers (GCP, Azure, AWS) is one of the most challenging aspects of modern cloud-native operations. In this session, we'll explore how k0rdent provides a declarative approach to multi-cloud multicluster management, and how Istio service mesh enables seamless application deployment and communication across clusters spanning multiple cloud providers.

We'll dive into real-world scenarios where we've deployed applications across multi-cloud clusters (GCP, Azure, AWS) using k0rdent's declarative approach for multi-cluster orchestration. You'll learn how to:
- Set up and configure k0rdent for multi-cloud multicluster orchestration
- Manage Kubernetes clusters across GCP, Azure, and AWS declaratively
- Deploy applications with Istio service mesh for cross-cloud, cross-cluster communication
- Handle traffic management, security policies, and observability across multi-cloud clusters

This talk includes live demos showing the complete workflow from multi-cloud cluster registration to application deployment, with practical insights on what worked, what didn't, and lessons learned from production multi-cloud multicluster deployments.
