Kubernetes Multi-Cluster Management in Practice
Overview When your business scale grows beyond what a single cluster can handle, multi-cluster becomes an inevitable choice. Reasons include: single cluster node limits (5000 nodes), multi-region deployment, hybrid cloud strategy, fault isolation, and compliance requirements. But multi-cluster management complexity grows exponentially—how to deploy applications across clusters, discover services cross-cluster, synchronize configurations, and handle failover. This article systematically covers multi-cluster architecture patterns, mainstream management tool comparisons, and practical solutions for cross-cluster service discovery, CI/CD, and disaster recovery failover....
