How SR Linux Lets You Take Control Of Your Data Center

We explore SR Linux, the network operating system developed by today’s sponsor Nokia. Why should you care about the network OS running in your data center? Nokia designed SR Linux to support automation, orchestration, and customization. We’ll dig into SR Linux’s support for YANG and gNMI and how that ties into northbound orchestration platforms, how SR Linux provides streaming telemetry, and Nokia’s development kit that lets you customize this Linux-based network OS. Our guest is Igor Giangrossi, Sr. Director, Consulting Engineering at Nokia. | LISTEN NOW

IPv6 Security Essentials

You’re already running IPv6, even if you don’t know it yet. Your remote users are using it at their homes, your printers come with it built into the kernel, your generals are using it on their mobile phones (check out our news headlines section). So let’s stop trying to disable it whack-a-mole style, and start making an IPv6 security plan. Scott Hogg from the IPv6 Buzz podcast joins the show to walk us through the basics: What questions to ask your vendors; How to explain the benefits of IPv6 to your bosses; How to think about firewalls in light of IPv6’s ephemeral addressing; and much more.  | LISTEN NOW

Tech Hiring is Borked

Life isn’t easy for someone looking for a job in tech. There are lots of content mills pushing the idea that if you just pass this one six-month course, you’ll have a six-figure career in no time. There are lots of hiring companies who make job applicants jump through a ton of hoops, but often find themselves interviewing candidates who don’t have any deep, substantive knowledge. Kyler, Ned, and guest Andrew Brown take an honest look at the current tech job market ecosystem, give a few career tips, and tell their own long-runway career stories. | LISTEN NOW

Wasm is Not Here to Take Your Containers

Is WebAssembly (Wasm) here to replace containers? Not really, says guest Matt Butcher. Instead, Wasm is here for a specific kind of workload: One that needs to start super fast (under a millisecond), handle something, and then shutdown. Containers are still best for running very long, I/O intensive multithreaded workloads. Matt, Michael, and Kristina discuss how this new technology process represents the third wave of cloud computing. | LISTEN NOW

Kubernetes Networking Essentials

Where there are containers, there is networking. Today we dig into the networking that underlies Kubernetes, the open source orchestration platform for container-based applications. Our guest Karim El Jamali takes us through the essential concepts: Nodes, pods, clusters, CNIs, virtual ethernet pairs, ingress controller, eBPF, and service meshes. As container-based applications grow in popularity, it’s critical for network engineers to stay up to speed in this area. | LISTEN NOW
