Physical network gear isn't going anywhere

For decades, hardware has reigned as king in the network, but the deluge of hype surrounding cloud, virtualization and software-defined networking has some asking how long physical network gear can hold on to its crown.

As we see in this edition of Network Evolution, however, even in today's software-defined and virtualized networks, hardware still has a firm foothold. Virtual overlays need hardware underlays; SDN fabrics require network gear; physical switches handle east-west traffic and physical routers connect data centers to the outside world.

Yes, the role of physical network gear is evolving in the SDN era, but it won't disappear anytime soon. Find out how early adopters are using hardware in their virtual environments.

Also in this issue, learn why content delivery network services have become more affordable, with a plethora of new options available to meet a wide variety of needs. Even some small and midsize enterprises now find CDN services -- once prohibitively expensive for all but the titans of media -- within their reach. Find out how such organizations have already put them to good use.
