the motive is simple, price...why buy a box from Cisco if you can buy SDN box for 1/10 of the cost?...that is why the overall networking hardware revenue is descreasing and Cisco stock suffering (and others who produce high end equipment, Cisco is just an example as they are still number 1)
It will take a lot for SDN to move well beyond big data centers. There needs to be an opportunity as well as a motive for doing so. It is a good sign that Amazon and Microsoft are adopting SDN, however. It shows that broader adoption is possible.
Why are surpised Rick?...the whole concept of SDN is to lower the networking cost and get free of expensive Cisco boxes...I would expect Amazon to be the first to jump on this concept...with Google, Facebook etc quickly to follow...in my view in 5 years the whole market will move over, at least in new purchases...Kris
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
