What is NFVI?

NFVI (Network Functions Virtualization Infrastructure) is the hardware and software components required to support the virtualization of network functions. It provides the environment to deploy and manage virtualized network functions (VNFs), such as routers, firewalls, and load balancers, as software on standard server hardware, instead of dedicated hardware appliances. NFVI commonly includes compute, storage, and networking resources, managed by a virtualization layer.
