Containers have started to surface in the telecommunications market, most notably in the area of network functions virtualization (NFV), and its counterpart, SDN (software-defined networking). Yes, it’s time to introduce container NFV and container SDN.
SDxCentral analysts believe that the combined SDN & NFV market will grow to nearly $105B by 2020, with a CAGR of 44% over the 5 years from 2015 to 2020, eight times the growth rate of the broader total available market. The portion of network purchases influenced by virtualization is anticipated to increase from 16% in 2015 to almost 80% by 2020.
The concept for NFV originated from service providers who were looking to accelerate the deployment of new network services to support their revenue and growth objectives. The constraints of hardware-based appliances and the need to control operational expenses (OpEx) drove several service providers to form the NFV ISG (industry specification group) under European Telecommunications Standards Institute (ETSI) to help develop the concepts, architecture and standards necessary to make NFV successful. NFV is a new approach to designing, delivering and managing network services that decouples the network functions proprietary hardware appliances so they can run in software on COTS (commercial off-the-shelf servers).
Key benefits of container NFV include:
