The Opportunity for OpenShift Infrastructure

Today we tackle the generational infrastructure shift that’s keeping IT leaders awake at night: OpenShift virtualization adoption. We dig deep into why organizations are struggling to migrate from traditional VM-focused infrastructure to Kubernetes-managed infrastructure. We explore the real hurdles blocking this transition and unpack the strategic positioning that matters when you’re moving to container-orchestrated infrastructure. This isn’t about dumping everything into Kubernetes and calling it done, we examine what it really takes to use Kubernetes as your infrastructure abstraction layer while navigating the operational realities that make or break these migrations.

Container Driven Architecture

In this episode, we continue our dive into the changing architecture of IT infrastructure and look at how containers and container platforms are changing. We also look at the fundamental nature of what people want to buy, accelerated by VMware Broadcom, making virtualization platforms much less attractive, and the shifting landscape here. This is work that is based on a presentation that I’ve been giving around the shift towards open shift virtualization and Kubernetes in general.

Is 2025 even harder than we expected?

We review 2025 predictions today and dig into why I think this year is going to be both boring and terrifying for a lot of enterprise IT leaders. That, of course, spans Amazon, Reinvent storage, VMware, AI, and Agentic AI – we run the gamut on what is coming and why this is actually going to be a very challenging year.

Virtualization in Containers (KubeVirt, OpenShift Virtualization)

In this episode, we dive deeper into the new architectural trends for infrastructure designers in this coming decade, which is a transition from virtualization platforms first like VMware into containerized platforms first. But this time, we talk through the use of virtualization in containerized systems – keeping VMs but with what changes are necessary to make a containerized virtualization platform dominant instead of a virtualized virtualization platform.

BootC created Bare Metal Containers [TechOps]

We dive deep into the technical details of BootC – a Red Hat-led technology that uses container-like definitions to describe machine boot processes. BootC is an important development, especially as companies embrace containers and seek a unified approach to machine configuration.

RackN CTO, Greg Althaus, provides an in-depth overview of how BootC works, its key capabilities, and the potential benefits and challenges for operations teams. They explore topics like BootC’s relationship to containers, the concept of immutability, different deployment methods, and the operational considerations around managing BootC at scale.

This conversation offers a balanced, non-Red Hat perspective on BootC, highlighting both its technical merits and the significant operational work required to successfully adopt and integrate it. Listeners will come away with a nuanced understanding of this emerging technology and the factors organizations should weigh as they evaluate BootC for their infrastructure.

Containers Manager [TechOps]

In this episode, we continue our TechOps series, diving deep into the topic of container management. As containers become increasingly mainstream, the need to effectively manage and orchestrate these lightweight, purpose-built environments is crucial.

We’ll explore the distinctions between container management and orchestration, discussing the different tools, techniques and trade-offs involved. We’ll also hear insights from the RackN team on how they’ve approached container lifecycle management within their own infrastructure management platform, Digital Rebar.

This is a rich discussion that touches on everything from Kubernetes to system design trade-offs. So let’s jump in and learn how to wrangle those containers!

Containers and Walled Gardens

We start talking about walled gardens and the momentum and push that causes us to get into vendor active environments in this episode. This is going to be a multi-part discussion where we look at the drivers of AI in the future.

In this case, we used up a lot of time before this recording talking about Kubernetes and what’s next for Kubernetes and containers, as well as how that ecosystem has been shaping up. This conversation is about the wall gardens that could be broken down, and in some cases, have actually been built taller because of containerization and Kubernetes and infrastructure and how infrastructure works.

After that background before going into the discussion, we pick it up on how these ecosystems and walled gardens are self reinforcing as well as chinks in the armor that will allow us to go back to interoperable standards.

Kubecon Retrospective

Klaus and I go through what happened at the Kubecon North America event in Detroit. Specifically, lessons learned in watching how the community reacts to new technologies like CRDs, declarative programming, and cluster APIs.

We also discuss the health of the community and the operators and vendors who were involved.

We give our impressions and insight – this conversation deep dives into practical use and futures in Kubernetes.

Rob’s Hot Take:


In the November 1st DevOps Lunch and Learn, Rob Hirschfeld reflects on the Kubernetes KubeCon retrospective, highlighting the profound impact beyond a platform. The adoption of Custom Resource Definitions (CRD), operators, declarative programming, and GitOps represents a fundamental architectural shift, transforming how applications are built and architected. This shift, witnessed in cloud-native Federation and architectures, marks a significant departure in thinking and process, redefining how systems are addressed and services are communicated. The podcast encourages a broader understanding of the trend, inviting listeners to explore these transformative concepts and join the ongoing discussions at the2030.cloud.

What We’re Watching At Kubecon

How do Helm charts and operators interact with Kubernetes? Today we have a fascinating discussion about the interesting components of Kubernetes including Helm charts, admission controllers and things that are changing and being revised and updated.

We discuss potential topics in anticipation for Kubecon, and if you’re at all interested in Kubernetes, whether you’re attending the conference or not, you will find this to be a must follow list of topics related to Kubernetes.

What’s up with Containers for 2022

This discussion sifts into tactical concerns for containers in the near term. We’ve gotten far with containers and Kubernetes. But what about process controls that we need to wrap around containers?

We talked through how we need to be thinking about containers now that we have good control surfaces around them to make things work. If you were using containers and Kubernetes, this podcast will certainly inform your thinking.
