NFV and DevOps Converging to Bring Telecom Lessons to the Enterprise

American poet Robert Frost began “The Road Not Taken” with “Two roads diverged in a yellow
wood.” But when looking at the quickening pace of transformation in NFV, it might be more
appropriate for us to talk about how the two roads of NFV and DevOps are beginning to
converge.
Forgive the lyrical mashup, but there is something poetic happening as the technologies and
business models that underpin network virtualization mature. In the year ahead, we’re going to
see the convergence of NFV and DevOps—developed by telecoms—making its move into
enterprises. This “Enterprise NFV” shift will benefit enterprise operators of large, global
networks and hybrid cloud deployments.
Telecoms like AT&T, Deutsche Telekom, Telefonica, and China Mobile embraced NFV in 2016,
driven by the maturity of open source projects like OPNFV, Cloudify, ARIA, Open-O,
OpenStack, and Kubernetes. At the same time, the business models for VNFs are beginning to
modernize, adapting to fit modern, scale-out design principles. The result of these shifts is that
enterprise operators of big networks are beginning to pay attention to what service providers
have achieved with NFV.
This enterprise NFV shift allows for network management and orchestration services to become
an integrated part of the application design and deployment process—DevOps. In essence,
Enterprise NFV allows the network to “follow the app” through its lifecycle, automatically and

2. Enterprise NFV allows the network to “follow the app” through its lifecycle, automatically and
dynamically configuring network services to facilitate application development, testing and
scaling.
A simple example of this can be seen in the initial deployment of an application to a private
cloud. That application is likely to need network changes like configuration of security groups,
changing firewall rules, installing and configuring load balancers, DNS operations and IPAM
management. Open source tools like Cloudify provide all the NFV orchestration needed to
support this deployment in a DevOps setting, automating installation and deployment,
monitoring of KPIs, and auto-healing and auto-scaling based on those KPIs.
That’s a reasonable example to illustrate how NFV and DevOps are already uniting for
telecoms. Now, let’s consider a more complex—and more likely—scenario that we’ll see more
and more of in 2017: hybrid cloud NFV for large enterprises.
As enterprises increasingly adopt hybrid cloud in the year ahead, they face a new level of
network operations complexity. NFV and DevOps offer compelling benefits for scenarios like
bursting, where the network must be automatically and dynamically reconfigured to adjust load
balancing and traffic steering and to re-configure firewall rules and implement routing changes.
Similar to bursting, blue/green operations refers to load sharing between two clouds, which is
useful for testing new applications or version in a controlled setting. It demands automated
network reconfigurations as applications move from dev/test into production. The merger of
NFV and DevOps gives enterprises using blue/green a telecom-proven approach to achieve this.
Enterprises benefiting from the union of NFV and DevOps in 2017 will look to standards-based
orchestration to get them there, just like telecoms have with standards like TOSCA and open
source orchestrators like Cloudify. Enterprises likely will want just one NFV orchestration
manager, one that supports application deployment across multiple clouds (from VMware to
OpenStack) as well as multiple data centers and availability zones.
The lessons of NFV and DevOps are moving from telecoms to the enterprise in the year ahead.
By this time next year, it will no longer be “the road less traveled,” but rather a well-marked
path for enterprises embracing DevOps and hybrid cloud. Choosing this path will make all the
difference, and you want to choose it before your competitors do.
