The conversation on software-defined networking (SDN) will be reignited at the ultimate SDN forum on next week in Santa Clara, Calif. Over the past three years, SDN has captured the attention of enterprises and service providers. Primary factors driving the consideration of SDN include the need for provisioning more business imperative application services and tackling network complexity. Business cap-ex on network hardware is only at about 15 percent of overall hardware spending, while op-ex spending has been unpredictable and quite high, even up to 35 percent of overall op-ex costs. However, most CIOs are pursuing an SDN architectural approach primarily for delivering and scaling reliable business services within predictable timeframes.
Barriers to SDN Adoption
However, while SDN has been in focus over the few years, most of the validation thus far has been conceptual or demonstrations of controllers with limited capabilities. The upcoming SDN forum will be a great venue to discuss enterprise customers who are looking for validation through proven use cases, particularly those that address the needs of varying architectural needs. Real promise of SDN is to deliver automated solutions at a large scale. Customers are expecting a logically centralized SDN control plane to deliver high scalability, high performance, high availability, and resilience.
While a few proprietary SDN controllers developed by vendors or cloud providers, such as Google, have some of these capabilities, they are not available to the developer community in the industry to use and further innovate. Proprietary technologies have often limited availability of skilled workers in every facet of technology. These barriers have caused customers to take a cautious approach to SDN deployments and curb their consideration to a few targeted use cases on legacy hardware. The latter discussion points justify the strong need for an SDN forums such as the one organized by the Open Networking Summit.
What to Expect in the Next 12 months
- In addition to separation of control plane from data plane, SDN deployments have to consider logical centralization of the control plane and enable mission critical capabilities such as performance, scalability, and resilience;
- Much like what Linux and virtualization did for RISC/Unix server business, SDN has the potential to disrupt proprietary switching technologies and embrace white boxes driving down TCO while improving enterprise network agility. Any SDN deployment strategy has to include adoption of white boxes over the next 24 months;
- For SDN to truly have an impact for businesses, it needs to be easily accessible to development and orchestration functions for application architects and developers. Any SDN deployment strategy has to include integration of orchestration tools within the SDN control plane.
At the Open Networking Summit in Santa Clara, Calif., there will be panel discussions on enterprise adoption of SDN with participation from several enterprise customers including: Credit Suisse, Deutsche Bank, Samsung, NSA, among others. The panel discussions will be an open conversation covering key topics including:
- Key business and operational benefits of adopting SDN in the enterprise
- Factors driving use cases’ prioritization in enterprises
- Early experience on pilots and proof of SDN concepts
- Panel members’ vision on deploying SDN over the next few years
- Topics relating to skills, training, and organization
- Transformation to a DevOps model and its impact on SDN deployments
- Expectations from panel members on open source SDN tools
At ONS 2015, we have assembled the “who’s who” in the networking industry, as well as marquee enterprise customers to present experiences on a broad range of SDN deployment use cases. You won’t want to miss it.
