All good things must come to an end, and in this case that means saying farewell to Kubernetes Unpacked. In this final episode, Michael and Kristina pack up the Kubernetes Unpacked podcast. They look back on covering issues including sustainability, security, open source projects, and certifications. They thank the professionals who joined the show as... Read more »

Kubernetes turns ten years old this summer. We take the opportunity to look at where it’s been and where it’s going. While many other open source projects folded over time, Kubernetes took the world by storm with the support of diverse entities including CNCF, Microsoft, AWS, Google, RedHat, and individual contributors. Moving forward, we predict... Read more »

Observability is foundational to application and infrastructure performance. That’s why it’s fitting that OpenTelemetry is the second most active project in the CNCF after Kubernetes. Today CNCF ambassador Dotan Horovits tells us about the project: OpenTelemetry is a uniform, vendor-agnostic observability framework for generating and collecting telemetry data across both infrastructure and application, across different...

Whether you want to migrate legacy applications to Kubernetes in order to save the whales or for any other reason, Konveyor is here to help. Savitha Raghunathan joins us today to walk us through the open source tool. The basics: You input the application’s source code (any language that has a language server) and Konveyor... Read more »

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... Read more »

In this episode of the Kubernetes Unpacked Podcast, Kristina and Michael catch up with Mark from Yellowbrick to talk about all things underlying architecture. Very rarely do we get a vendor to chat about what’s going on underneath the hood and how a particular application stack/tool is running, so this was an awesome episode! Mark... Read more »

CI/CD is not a villain. GitOps is not some kind of Kubernetes way of sneaking around it. In fact, GitOps falls under the CI/CD umbrella. Marcus Noble joins the show today to talk about how he uses a Kubernetes-native, open-source CI/CD framework called Tekton to test Kubernetes cluster creation, configuration, and deletion based on changes...

Kubernetes is designed to be highly scalable and highly dynamic… a perfect habitat for cryptominers to terminal shell into and then exploit your workload’s resources to the max. And that’s just one example of security threats Kubernetes users need to prepare against. Nigel Douglas from Sysdig joins Michael Levan and Kristina Devochko to give you... Read more »

What are we talking about when we are all talking about private clouds? On-prem? Hybrid? Virtualization? Where does hardware fit into it all– and would younger engineers even know what to do with a physical piece of hardware? Driven by Broadcom’s acquisition of VMare and the anticipated rising costs of VMare licenses, enterprises are exploring... Read more »
