Telecommunications giant Vodafone Group has seen some significant efficiency gains by going smaller in terms of its cloud application management. Fran Heeran, head of network virtualization, software-defined networking (SDN), and network functions virtualization (NFV) at Vodafone, said the carrier is seeing around a 40 percent improvement in resource usage from going with containers compared with virtual machines (VMs). Heeran made the comments during an event at this week’s Mobile World Congress show looking at the use of Kubernetes with the Open Network Automation Platform (ONAP). .
