Live from the SDN World Congress Show in The Hague, Pravin Mirchandani, CMO, EKINOPS, reflects on the industry challenges steering the dialogue at this year’s conference.
In Gartner’s hype cycle, there is an inevitable time of disillusionment that follows the initial excitement of a new technology. At the SDN World Congress this feels different: although we have probably passed the peak of inflated expectations, there is less a trough of disillusionment, rather a set of major impediments that need to be cleared away in order to achieve the nirvana of SDN/NFV. Most actors can see what needs to be done and are steadfastly supporting the initial objectives but my impression is that breaking through to achieve the goals of network virtualization is like pushing through the famous glass ceiling. Though not created by prejudice, as in the traditional definition of glass ceiling, the barriers are real and there are many.
Glass Ceiling 1: Complexity One of the goals of software-defined networking is to reduce dependence on an army of network experts, who are difficult to recruit and retain, expensive to hire and prone to error. What’s clear is that what they do is indeed complex; and converting their expertise and processes into automated software processes and APIs is equally if not more complex, as there is a distinct lack of established practices and field-proven code to draw upon. Many of the speakers at SDN World Congress mentioned the issue of complexity and this was a constant theme in the corridor discussions. Laurent Herr, VP of OSS at Orange Business Services stated that Orange estimated it would take 20,000 man-days to convert their tens of IT systems to achieve virtualization.
Glass Ceiling 2: Culture Another common theme was the issue of culture. Telcos have been organised to deliver the ‘procure-design-integrate-deploy’ cycle for new services and have a well-established set of linear processes and organizational silos to achieve it. Introducing virtualized services however requires a DevOps culture based on agility, fast failing (anathema to the internal cultures of Telcos) and rapid assembly of multi-skilled teams (especially collaboration between network and IT experts) to deliver new outcomes, frequently, fast and reliably. Achieving a DevOps culture was one of the most frequently cited challenges by the Telco speakers at the Congress. Another common word they used was transformation.
Glass Ceiling 3: Lack of Expertise It’s difficult to estimate the number of engineers that really understand the principles and practices of virtualization but they probably number in the low hundreds across the globe. Given the ability of the vendors to pay better salaries, it’s a safe bet that the majority work for them rather than for the Telcos. Growing this number is difficult as it requires combining IT, programming and network skills. Creating collaborative teams helps but finding or training people to achieve mastery of the different skills is a challenge for the whole industry. This was more of a corridor conversation rather than openly cited by the speakers but it is a glass ceiling nevertheless.
