Summary

On October 7, 2024, ETSI Network Functions Virtualization (NFV) conducted a workshop to discuss the future direction of the ETSI NFV Telco Cloud and the role of artificial intelligence (AI). This analyst opinion summarizes the key discussions from participants of this workshop, including Deutsche Telekom, ETSI NFV, Huawei, NTT DoCoMo, Open Infrastructure (OpenInfra), Orange, Telenor, and Telefónica. The industry recognizes the increasing complexity of cloud native network operations. Operators that have advanced through their cloud native migrations believe transitioning to GitOps-based lifecycle management of the network elements is foundational. Their new approach relies on declarative deployments and management of the desired network state. The role of GitOps and AI in improving automation and intelligence for NFV management and orchestration (MANO) is being explored.

Operational complexity is high for cloud native networks

Operational complexity is increasing as network systems move away from monolithic appliances to virtualized or cloud-based networks. A cloud native network follows a layered architecture (as shown in Figure 1). It is influenced or shaped by three key trends:
