There are plenty of reasons for organizations to use NFV, including the following benefits:
- Better communication
- Reduced costs
- Improved flexibility and accelerated time to market for new products and updates
- Improved scalability and resource management
- Reduced vendor lock-in
Better communication and information accessibility
In addition to managing networks, NFV improves network function by transforming how the network architects generate network services. This process is performed by using an architectural and creatively designed method to link together different network nodes to produce a communication channel that can provide freely accessible information to users.
Often used to great effect for decoupling network services, NFV can also be used as an alternative for routers, firewalls and load balancers. One of the appeals of NFV over routers, firewalls and load balancers is that it doesn’t require network proprietors to purchase dedicated hardware devices to perform their work or generate service chains or groups. This benefit helps to reduce the cost of operating expenses and allows work to be performed with fewer potential operating issues.
Because VMs have virtualized services, they can receive portions of the virtual resources on x86 servers, allowing multiple VMs to run from a single server and better scale, based on the remaining resources. This advantage helps direct unused resources to where they’re needed and boosts efficiency for data centers with virtualized infrastructures.
NFV allows networks the ability to quickly and easily scale their resources based off of incoming traffic and resource requirements. And software-defined networking (SDN) software lets VMs automatically scale up or down.
Better resource management
Once a data center or similar infrastructure is virtualized, it can do more with fewer resources because a single server can run different VNFs simultaneously to produce the same amount of work. It allows for an increased workload capacity while reducing the data center footprint, power consumption and cooling needs.
Flexibility and accelerated time to market
NFV helps organizations update their infrastructure software when network demands change, starkly reducing the need for physical updates. As business requirements change and new market opportunities open, NFV helps organizations quickly adapt. Because a network’s infrastructure can be altered to better support a new product, the time-to-market period can be shortened.
Reduced vendor lock-in
The largest benefit of running VNFs on COTS hardware is that organizations aren’t chained to proprietary, fixed-function boxes that take truck rolls and lots of time and labor for deployment and configuration.
