Present-day enterprises are increasingly turning to network virtualization as an alternative to physical devices. This is especially true in branches where there are often space, power, and support constraints. By embracing network function virtualization (NFV), it is possible to reduce branch network infrastructure to a single rack unit – a compute node on which virtual appliances like virtual firewalls, virtual SDWAN appliances, and virtual branch gateways can be deployed on-demand. Original equipment manufacturers (OEMs) are providing all-in-one solutions which include compute, management and orchestration tools, and virtual appliances for turnkey deployments. Alternatively, an enterprise can also choose a variety of commercially available virtualized network functions (VNFs) and off-the-shelf servers.
