SD-WAN and Network Infrastructure: Why They Matter
Today, any network infrastructure project without (at least) server virtualization is unthinkable and, in larger organizations, there is an automatic provisioning of resources for applications (which, if applied to the old architectures, would make the computer park occupy an entire neighborhood).
The new generation of network infrastructure is also driven by other factors, such as readiness to provide new applications (with the implications of capacity, security and QoS), as well as financial aspects. However, in software-defined networks (SDNs), the management of these resources is passed to an orchestration layer and can be presented as services.
