Jerrod Gerth, Principal Solutions Architect at Alcatel-Lucent, explored software-defined networking (SDN) in a presentation to Argyle's CIO membership at the 2015 Chief Information Officer Leadership Forum: Spotlight on Financial Services in New York on Sept. 16. In his presentation, Gerth discussed how "a variety of things ... fall under the software-defined networking bucket."
According to Gerth, the goal of SDN is to make networks more programmable. As such, there's been a consumption shift inside the data center, Gerth said. With the evolution of containers, Gerth noted the unit of measure for networks has changed from a server to a virtual machine. The shift toward containers also has helped many organizations save time, Gerth added: "With containers now, we're getting down to minutes and seconds. We did a demonstration for another group earlier this year where we took 100,000 containers and we instantiated those hundred thousand containers in less than ten minutes. We went from zero to 100,000 containers in less than 10 minutes. It’s incredible velocity for provisioning inside of the data center."
SDN must remain flexible and keep up with rapidly evolving "micro services," Gerth said. And with containerization, Gerth pointed out organizations can benefit from fast, portable networks: "We reduce the number of errors in network provisioning. Then we also gain mobility as well. This configuration is now portable; it’s not fixed to a specific location or a specific address. It could be in the data center or in any one of our data centers. It could be in the public cloud. We have a configuration now that is fast, fewer errors and mobile and portable as well."
Jerrod Gerth has been providing free, on demand, “what do you mean you don’t have time?” IT support for family and friends for over 20 years. He earns a living working as a Principal Solutions Architect for Nuage Networks focusing on some of the largest and most complex deployments. Over the last 16 years, Jerrod has held similar positions at Vyatta, Brocade and Foundry Networks. He and his wife, Mandi, live in Dallas/Fort Worth, where they are trying to raise at least one of their five children who will take care of them in their old age.
