Network Functions Virtualization (NFV) system consists of three key Infrastructure elements. These elements are:
• NFVI (Network Functions Virtualization Infrastructure)
• VNFs (Virtual Network Functions)
• MANO (Management and Orchestration)
Let’s talk about each of these elements one by one.

NFVI (Network Functions Virtualization Infrastructure)
NFVI (Network Functions Virtualization Infrastructure) is the part that is consist of hardware and software elements of the network. NFVI has sub parts, these parts are:
• Hardware Resources
• Virtualization Layer
• Virtual Resources
Hardware Resources consist of hardwares of network devices,servers, storage etc. These hardare resources are shared and used by VNFs (Virtual Network Functions).
Virtualization Layer decouples the hardware resources of the NFVI. It compute, storage and network resources are emulated. It is responsible abstracting the physical resources and by doing this VNF uses this resources as independent.
VNFs (Virtual Network Functions)
VNFs (Virtual Network Functions) part consist of two key elements. These are :
• VNF (Virtual Network Function)
• EMS (Element Management System)
