‘From core to edge’ — Telefónica Germany on cloud-native shift

Telefónica Germany is treating cloud‑native networking as a complete overhaul, not a software upgrade. Chief technology and information officer Mallik Rao says the move to cloud‑native has to run through the whole company: how the network is designed, how it is run day to day, and how teams work, from the core network out to the edge.

Rao notes that telecom operators know how to build and operate traditional networks, but those strengths can slow them down when they try to adopt cloud‑native methods. The hardest part is less about tools and more about changing architecture, operations, and internal culture at the same time.
