Standardization, virtualization and disaggregation are foundational elements of the wave of cloud architectures sweeping the enterprise and the service provider landscape. Software-defined networking (SDN) has been one of the key drivers of innovation in networking within these architectures. And network virtualization (NV), as one of the main use cases enabled by SDN, is growing and thriving. Both NV and SDN provide significant benefits to end-users, whether enterprises, cloud service providers or communications service providers. Improved agility and flexibility, enhanced security, reduced operational costs, better scaling and many other significant benefits have been achieved by network virtualization adopters across the board. Networking in most clouds, public, hybrid or private, achieve their connectivity magic through use of network virtualization technologies.
At the same time, SDN has also enabled improvements in the WAN, especially with the interest in SD-WAN by enterprises and roll-out of managed SD-WAN offerings by communications service providers. While SDN principles have taken hold across end-users and networking vendors alike, we unfortunately don’t see large numbers of commercial sales of SDN controllers. In addition, there have been few successful startups focused on just shipping SDN controller software. Nevertheless, despite commercial challenges on selling pure SDN controllers, the market for SDN technology and network virtualization (and SD-WAN), in particular, has blossomed and grown significantly, with vendors like VMware claiming near $1B sales of their network virtualization product.
The open source scene in SDN has likewise matured, with continued momentum behind two leading SDN controllers, OpenDaylight and ONOS, both hosted by the Linux Foundation. With OpenDaylight as a platform foundation, we see the emergence of a second generation of SDN companies, led by Lumina Networks (formerly Brocade SDN) and Inocybe, who are looking to different business models to capture value. Time will tell if they will succeed where the previous generation did not.
And as network virtualization takes hold in enterprises and service providers, public cloud providers like Amazon, Microsoft Azure and Google have built out improved network virtualization capabilities, making them an important part of the ecosystem. In fact, many businesses will get their first taste of network virtualization and SDN capabilities through using VMs and containers hosted on these public clouds. We expect to see significant innovation over the course of the next year from these public cloud providers.
