NFV Infrastructure refers to a network architecture concept that allows network services to be virtualized and run on standard hardware instead of dedicated appliances. This approach enables greater flexibility, scalability, and cost efficiency in managing network resources. By decoupling network functions from physical devices, organizations can deploy and manage services more dynamically. The core components of NFV Infrastructure include virtual machines, hypervisors, and orchestration tools. These elements work together to create a virtualized environment where network functions, such as firewalls and load balancers, can be easily provisioned and managed. This leads to faster service deployment and improved resource utilization.
