The mobile industry is at a tipping point. In the 4G/5G era, the status quo network economics are unsustainable. The cost-per-bit models and network architectures that dictated 4G strategies will not support 5G use cases.
Let’s look at 5 critical factors, and examine how network virtualization from the core to the RAN transforms mobile network economics through cost savings and introduces the network flexibility and service agility needed to drive and protect revenue.
1) NFV & SDN Need Native Software Design
Cloud native software design leverages containerization, stateless processing, and microservices to create VNFs that use compute resources more efficiently and reliably. Rather than just scaling up or down, native VNFs scale out to spread the capacity load across available compute resources. Native VNFs achieve the flexibility, scalability and operational efficiency promised by NFV. Ultimately, NFV will transform mobile networks to achieve web-scale, full-service automation and enable Platform-as-a-Service (PaaS) offerings, completely changing the economic equation for mobile operators.
