The current state of the software-defined network (SDN) sector: plenty of surveys predicting fast growth and one high-profile study that illustrates the dangers of fast growth on a category’s long-term image.
Here is what people are saying:
- CIO reports that IDC forecast that the SDN market for enterprise and service providers will grow from $960 million last year to more than $8 billion in 2018. That’s a compound annual growth rate (CAGR) of 90 percent.
- The Linux Foundation, which runs the OpenDaylight program and its summit, found that 73 percent of its membership has already or plans within the next year to deploy an SDN, with 24 percent in the investigation phase. It’s fair to note that members of the organization are likely to be partial to SDN and network functions virtualization (NFV). The survey should be seen within that context.
- MarketsandMarkets predicts that the SDN (NFV) sectors will be worth $45.13 billion in 2020, a CAGR of 86.1 percent.
The news on this front was not good for SDN, according to The Register, the Hype Cycle…
…suggests software-defined networking (SDN) has arrived at the trough of disillusionment, meaning that people for whom it has no appeal beyond marketing will give up and leave the technology for those that actually need it.
Techniques and technologies associated with SDN, such as virtual switches, SD-wide area networks (SD-WANs) and SDN applications, fare much better than the core technology. This may say as much about the Hype Cycle approach and the people whose opinions are included as it does about SDNs.
Indeed, overwrought expectations are a part of the landscape for any ambitious new technology. In the world of SDN and NFV, however, vendors and others in the ecosystem should work with extra diligence to keep expectations under control. The promise is great, and that means that disappointment will be just as extreme. That’s a big deal in a sector that touches on the very fabric of the organization.
