Arista Networks’ EOS CloudVision software platform aims
to make the benefits of SDN a reality for the enterprise.
The term “software defined networking” (SDN) certainly means different things to different people. To the giant web companies, SDN means having the ability to create custom network software to enable functions that are unique to that organization. This requires dedicated software engineers and a networking team large enough to run and support the custom networks. There are somewhere in the neighborhood of 30 companies that have the resources, size, and scale for this model of SDN to make sense.
For businesses below this tier – service providers and enterprises – SDN means the promise of automation and cloud scale but also a high level of complexity, sometimes more complexity than the original network. A good rule of thumb for IT initiatives is that solutions should never be more complicated than the problem they’re intended to solve. This is one reason SDN deployments have been slow despite the fact that almost every organization I talk to today is interested in the technology. For SDNs to become pervasive in the non-web-scale tier, they must become easier to deploy.
