2015: Looking Ahead in the Networking Industry

2014 has been an incredible year in the networking industry. We've witnessed a transformation from point products to network platforms, furthering the movement toward software driven cloud networking.  At Arista, we are pleased to be a part of driving the pace of innovation for public, private and hybrid clouds, big data, security and virtualization. Here's what we see looking ahead to 2015:

  1. Accelerated uptake of building robust and resilient networks at layer 3 with overlays like VXLAN on top of that will continue.  Legacy networks will look even more like relics of the past and continue to have scale, stability and large-failure-domain issues in contrast to layer 3 spine/leaf designs which inherently scale out, have minimal fault domains combined with faster convergence.

  2. We will see continued success for open standards over proprietary vendor lock-in technologies.  Large open scale-out networks will win because they bring freedom of choice, enable a best-of-breed strategy, and deliver the best value for money.

  3. We will continue to see a massive shift from established legacy vendors to an ecosystem of openness and programmability for mobile workloads in big data and virtualization.

  4. Moore's Law plus overlay architectures bring reduction in tiers in the network from 3+ tiers to two-tier Spine/Leaf and single-tier Spline, enabling dramatically lower cost points for higher performance networks, similar to how server virtualization reduced CapEx/OpEx in the server world.

  5. The network will provide workflow-aware telemetry that goes beyond link counters by integrating with overlay controllers and orchestrators, rather than falling into the "app trap" of imagining the network should be in the business of special-casing each application.
