Network functions virtualization (NFV) allows service providers and operators to abstract network services, such as firewalling and load balancing, into software that runs on basic servers.
For operators and service providers, the holy grail of an NFV implementation is the ability to dynamically provision network components, services and applications in a matter of minutes rather than the weeks or months it takes to do so now.
Mobile operators and service providers are embracing NFV more quickly than anyone had expected, and experts are betting that the new technology will eventually make its way into the enterprise. However, business and technical challenges still loom in NFV.
In this Essential Guide, we explore NFV implementation basics and the potential benefits. We also break down current issues with NFV, as well as vendor approaches to the new technology.
1The ins and outs of NFV-
NFV: How does it work?
NFV virtualizes network services and applications that once ran on hardware appliances. In fact, network functions virtualization could replace many network devices with more flexible software running on bare metal servers, enabling a new kind of service chaining. Learn the basics of how NFV works, and how it could make its way into the enterprise.
Challenges and issues with NFV
It's clear what NFV can offer in terms of benefits, but challenges also exist. Some network experts argue a new network management model is needed for NFV and its implied orchestration. Operators will also face issues with NFV implementation, as well as with finding funding for the new technology.

4How SDN and NFV work together-
What is the relationship between SDN and NFV?
SDN and NFV aren't one in the same. In this section, experts explain the differences between SDN and NFV, while also taking a look at how each complements the other. Together, SDN and NFV provide powerful benefits to those in the mobile space as well as within service chain provisioning.
Together, SDN and NFV simplify service chain provisioning. David Jacobs explains how it becomes easier to spin up apps in enterprise and service provider networks. Continue Reading
