Using individual Virtual Network Functions (VNFs), a fully virtualized environment can be constructed by connecting or combining them as building blocks. On top of hardware networking infrastructure, VNFs run on virtual machines (VMs). They can run on multiple hardware boxes using all of their resources. In this article, we will discuss the architecture and components of VNFs, their advantages and limitations, and how they differ from NFV. What Are Virtual Network Functions (VNFs)? To achieve agility, flexibility, and dynamic scaling in network infrastructure, Network functions virtualization (NFV) and Software-defined networking (SDN) are being used in technology transformation. Software-defined networking (SDN) allows network administrators and operators to take complete control of their networks, and NFV replaces the network equipment with a virtualized infrastructure. On this virtual infrastructure, Virtual Network Functions (VNFs) will run and host. Virtual Network...
