Chapter 13. Conclusion
Mobile operators have moved from proof-of-concepts (PoCs) to trials to production using virtualized mobile network elements. This was first pioneered by Tier1 operators and we are seeing it being followed by Tier2 and Tier3 operators around the world. Virtual mobile network offer the operators freedom from vendor lock-in, ability to grow and shrink the network based on demand without having to order and deploy new hardware. This has been made easy to deploy due to the Orchestration and Management functions. Further operational gains can be gained by leveraging configuration automation tools such as Ansible by Red Hat. NEPs and Telcos are working against the backdrop set by ETSI NFV standards body in standardizing the way NFV can be implemented, deployed and managed.
