==Cloud-native Networknetwork Functionsfunctions==

From 2018, many VNF providers began to migrate many of their VNFs to a container-based architecture. Such VNFs also known as [[Cloud-Native Network Function]]s (CNF) utilize many innovations deployed commonly on internet infrastructure. These include auto-scaling, supporting a continuous delivery / DevOps deployment model, and efficiency gains by sharing common services across platforms. Through service discovery and orchestration, a network based on CNFs will be more resilient to infrastructure resource failures. Utilizing containers, and thus dispensing with the overhead inherent in traditional virtualization through the elimination of the [[Hardware virtualization|guest OS]] can greatly increase infrastructure resource efficiency.<ref>{{Cite web|title=Cloud-Native Network Functions|url=https://www.cisco.com/c/en/us/solutions/service-provider/industry/cable/cloud-native-network-functions.html|access-date=1 April 2021|website=Cisco}}</ref>
