NFV stands for Network Functions Virtualization. It is an architectural framework and technology that virtualizes network services traditionally performed by dedicated hardware devices. NFV aims to decouple network functions from proprietary hardware appliances, making them software-based and deployable on standard servers and virtualized environments.

Manager (VIM)
VIM acts as a control plane and provides a platform to launch
virtualized network functions (VNFs).
The VIM is responsible for managing the virtualized
infrastructure (VI), including the servers, storage, and
networking resources needed to support the VNFs
The VIM provides a number of benefits to service providers and
end users, including:
• Simplified management
• Improved resource utilization
• Enhanced security
