DevOps in networking begins to gain ground

Software development has benefited from a DevOps framework, which brings together software engineers and operating teams to collaborate in a continuous integration/continuous delivery model that helps automate and deploy code faster. DevOps in networking, however, is still an emerging concept. Many networks are still managed and updated using heavily manual processes.

In this issue of Network Evolution, find out how network virtualization and automation are leading enterprises to consider whether they can manage their networks through DevOps methodologies. As more network elements become software-driven, organizations will see a shift to DevOps in networking.

In addition to an emerging DevOps approach, the software-driven network brings with it a slew of new technologies and approaches to understand. From software-defined networking and software-defined WAN to network functions virtualization and virtual network functions, network professionals have to wade through options aimed at changing everything about how networks are built and managed. Read on as we sort out the subtle differences among these technologies.

And as virtualization enhances network design, it also makes the network a more attractive target for hackers. We also look at what security tools and services enterprises are investing in to boost network security in the cloud.

Finally, read how the Broward Center for the Performing Arts is using cloud-based network monitoring to keep its theater in the spotlight.
