SDN @ TEN – Key Observations

• SDN has many new faces!

- SD-WAN, SD-DC, SD-EPC, and so on. Software is the key word in SDx

• SDN is not really about cost reduction – it’s about service, market and value EXPANSION

• Much of SDN value today is around automation and service velocity

- Launch services fast, make them turnkey, capture new revenue

• Critical to gain experience early!

- Build a culture of software excellence with a value-creation mindset

SDN at TEN – Final Thought: Experience Matters

• Don’t wait for the perfect time when technologies finally emerge

- Technology will evolve, but there is value in experience

• There is plenty of value NOW!

- SDDC’s widely deployed – shift from IaaS to PaaS/CaaS happening now

- SD-WAN example: not perfect, not even open, but a big success for SDN

- Segment Routing is the next vehicle – deployable today!

• SDN is about value creation – not self-actualization

- Leverage the best technology available in a package that is ready to deploy!
