Explaining Kubernetes Controller Architecture

How does the Kubernetes admission controller work, what are the failure modes and what do we need to guard against?

Today, we discuss almost everything that you need to know to understand the admission controller process better and to think about it in a secure, robust and resilient way.

I can’t think of a better primer on today’s topic and Kubernetes architecture more generally, I am certain you will enjoy the discussion.

Rob’s Hot Take:

In the November 15th Cloud 2030 Podcast episode, Rob Hirschfeld delves into the intriguing topic of Kubernetes admission controllers, emphasizing how Kubernetes architecture fosters innovation by allowing admission controllers to function as a generic property, avoiding the need for direct embedding into Kubernetes itself. The discussion explores the open system created by admission controllers, which, while offering valuable capabilities, introduces complexity, overhead, and performance considerations. Kubernetes appears to have successfully balanced these factors, contributing significantly to the industry. For those interested in this fascinating conversation, the entire podcast is available at the2030.cloud, inviting participation in ongoing roundtable discussions.

Learning about eBPF Applications

Special guest Bill Mulligan (twitter.com/breakawaybilly/) talks to us about the use cases for BPF and how it works.

We discuss eBPF, the kernel extensions that allow you to write small programs that work inside of kernel space in a safe sandbox way. These have a lot of applications, and they’ve been creating a lot of hype inside of the Kubernetes community as a way to address networking shortfalls.

Our conversation starts broad, but eventually zeros in on eBPF. I know that you will learn a lot about how eBPF can enhance and improve your infrastructure operations environment.

Power Distribution And Green Infrastructure

We conceptualize data centers as core infrastructure components in today’s discussion about green infrastructure.

In our discussion about data centers as an industrial load that have peaks and valleys in demand, we dive into the grid as a connected system. We discuss how storage can disrupt the way power is generated and distributed, not only in the United States, but also around the world.

Distribution systems play a huge role in green infrastructure, just like networks. The way we assume that networks are available and robust, we have made the same assumption about power generation in the world to run these data centers.

These topics are all tied together, and you will see a lot of insights and similarities in how we solve and build green infrastructure.

Rob’s Hot Take:

In the June 2nd episode, Rob Hirschfeld emphasizes the importance of distribution in discussions about creating greener data centers. Recognizing how power is generated, its localities, and dealing with infrastructure peaks and valleys are crucial components. The shift from centralized to decentralized infrastructure, both for power and data centers, plays a key role in reducing reliance on distribution systems, enhancing resilience, and addressing interconnected challenges. Join ongoing conversations about green infrastructure at the2030.cloud to explore these complexities further.

Evolution of Networking Systems

How do we evolve technology in the future?  We centered the answer on networking, but in a very general way.

The ability for a vendor to distribute technology and then connect things together and then build networks of that technology is a core component of how networking is evolving.   Ultimately, this is about building technology systems.

Sadly, that led us into a very dark place where we really thought through who’s going to own all of that infrastructure and their motivations.  How can we make sure that the people’s needs and the systems and the vendors’ needs are well aligned?

Rob’s Hot Take:

Rob Hirschfeld, CEO and co-founder of RackN and host of the Cloud 2030 Podcast, reflects on the November 2nd DevOps Lunch and Learn session, which explored the motivations and impacts of building highly networked systems. While acknowledging the significant societal benefits of interconnected technology, Hirschfeld emphasizes the importance of understanding and mitigating the potential risks, particularly regarding data control and accessibility. He advocates for building inclusive systems that prioritize adaptability and service to the greater good, inviting listeners to explore the comprehensive discussion on these critical topics at the2030.cloud.

Edge Networking: Facebook, BGP and 5G

Edge networking is hard! Because before we can talk about edge networking, we actually have to talk about edge management and edge control, and what it takes to build resilient infrastructure and train people to use it.

In the first half, we’re talking about the challenges of managing infrastructure, using the Facebook outage of the week we recorded as a starting point for how challenging it is to build resilient infrastructure.

In the second, we talk about edge networking with solid insights about how challenging edge networking really is not just creating networks in edge locations, but what does it take to sustain an edge network and the integration and technologies over the course of multiple technology generations?

Rob’s Hot Take:

Rob Hirschfeld, CEO and co-founder of RackN and host of the Cloud 2030 Podcast, reflects on the October 5th discussion about edge networking, highlighting the conversation’s focus on the long lifecycle expectancy of edge technologies and the challenges associated with their maintenance and evolution. He emphasizes the need to address these critical topics in edge networking discussions, inviting listeners to explore the in-depth conversation at the2030.cloud.

Designing for 5G and Digital Twins

We talked about 5G, factories and edge infrastructure.

They are very interconnected because they live at the network edge and are sensitive to how we need to route traffic.

This is important as the basis for using digital twinning as a new user experience (UI/UX) around interacting with systems. This new approach is starting to emerge and it will be very network intensive, visually oriented, and involve overlaying the physical world with the virtual world.

How the heck are we going to connect all these things together?
