Understanding OPNFV 20 be deployed rapidly, in an automated fashion. By shrinking the time and expense from customer request to revenue by instantly deploying services, the time-to-break-even can go down significantly for operators. Reduced Capital Expenditure (Capex) NFV dramatically improves hardware utilization. No longer do you waste unused cycles on proprietary fixed function boxes provisioned for peak load. Instead you can deploy services with the click of a button, and have them automatically scale-out or scale-in depending on utilization. In another non-telco industry example, a gaming IT company, G-Core, was able to double their hardware utilization by switching to a private cloud. Using industry standard servers and open source software further reduces capex. Industry standard servers are manufactured in high volumes by multiple vendors resulting in attractive pricing. Open source software is also typically available from multiple vendors, and the competition drives down pricing. This is a win-win where reduced or elimination of vendor lock-in comes with reduced pricing. Additionally, operators can reduce capex by utilizing different procurement models. Before NFV, the traditional model was to issue an RFP to Network Equipment Manufacturers (NEMs) and purchase a complete solution from one of them. With NFV, operators can now pick and choose different best-in-class vendors for different components of the stack. In fact, in some areas an operator could also choose to skip vendors entirely via the use of 100% open source software. (The last two option is not for the faint-of-heart, and we will explore the pros and cons of different procurement models in the next chapter.) TIA Network's "The Virtualization Revolution: NFV Unleashed – Network of the Future Documentary, Part 6" states that the total opex plus capex benefit of an NFV-based architecture could be a cost reduction of up to 70%. Freed up Resources for New Initiatives If every operator resource is busy with keeping current services up and running, there aren't enough staff resources to work on new upcoming initiatives such as 5G and IoT. The side effect of reduced opex is that the organization will now have resources freed up to look at these important new initiatives, and so contribute to overall increased competitiveness. Or putting it another way, unless you fully automate the lower layers, there won't be enough time and focus
