Multi-cluster and geo-redundancy: federation, failover, DR

Why Single-Cluster Is Not Enough

Production telecom networks cannot rely on a single Kubernetes cluster for their entire 5G Core deployment. Geographic redundancy across multiple sites ensures service continuity during data center failures, network partitions, and planned maintenance. Regulatory requirements in many countries mandate that subscriber data remains within specific geographic boundaries, requiring distributed deployments across national regions. Latency requirements for edge computing use cases like autonomous driving demand UPF placement close to the radio access network. Multi-cluster architectures address all…
