Building a cloud-native network from core to edge
While some greenfield players are able to immediately embrace cloud-native network design and reap the benefits that come with it, those cases are few and far between. For most operators this is an incremental transition that gradually shifts from legacy systems to cloud-based systems. Through that transition, NFV provides some degree of automation and serves as a jumping off point for forward-looking investments.
Shekar Ayyar, VMware’s EVP and GM of Telco and Edge Cloud, described NFV as one “ingredient of a telco cloud. This is the idea that a carrier can take what were otherwise core network functions that were generally deployed on purpose-built hardware and you can now make them available as software workloads on top of infrastructure that’s virtualized by, let’s say, VMware.” The advantage here, just like in a typical data center, is decreased costs. But, for telcos, there’s the added benefit of service agility.
NFV gives way to a “broader thesis around how you can operate the entire telecom network as a cloud. You can provision resources from a telecom network, access them more on demand and deploy services much quicker.” He said VMware is a “strong believer” in the idea that, “You can’t do 5G…without a virtualized infrastructure.”
