Leveraging SDN and NFV for Comprehensive and Cost-effective Cyber Network Defense & Application Delivery

Last week I spent a few days in sunny (and crowded) San Jose, California at the NFV World Forum.  The theme this year was largely about open environments and interoperability, ushered on by the standardization efforts behind NFV, along with the related topics of carrier-grade service assurance and reliability.  I was fortunate to speak about how Radware is actively investing in open environments as the architecture becomes common platforms for commercial implementations.  Radware is implementing SDN and NFV in network security and application delivery domains to help service providers achieve radical cost reduction while benefitting from the advantages of cloud-based application services.

More recently there has been a lot of discussion about the value of an overlay SDN model vs. an underlay SDN model and the role of specialized hardware in either model. All of these discussions are important and they all are focused on key architectural characteristics of SDN.
