Real-world: Operator CNF deployments (Ericsson, Nokia, Mavenir)

Major Vendor CNF Architectures

Leading telecom vendors have adopted distinct approaches to cloud-native network function architecture. Ericsson Cloud RAN and Dual-Mode 5G Core decompose monolithic NFs into fine-grained microservices, with some control plane functions split into over twenty individual containers working together. Nokia Cloud-Native Core packages each NF as a Helm chart with common operational patterns across the portfolio. Samsung 5G Core uses a microservices architecture optimized for public cloud deployment. Each approach reflects different tradeoffs between operational simplicity, scaling granularity,…
