How eBPF and Cilium Are Reinventing Kubernetes Networking

Why doesn't traditional network security work in Kubernetes anymore - and what's replacing it? In this episode of Radio Cloud Native, Nick Chase of Mirantis sits down with Christian Hernandez and Nico Vibert of Isovalent (Cisco) to unpack how eBPF and Cilium are rewriting the rules of cloud native networking. They cover why IP-based security breaks down in dynamic Kubernetes environments, how identity-aware policies (labels and metadata) are taking its place, and what eBPF actually does at the kernel level to make tools like Cilium, Tetragon, and Hubble possible. They also dive into Cilium's place as an ideal CNI for Kubernetes for policy driven networking, as well as a new component they are dubbing the "Kubernetworker" (combining Kubernetes and Networking). The group will finish looking towards the future of networking and the changes that are still on the horizon as AI workloads become commonplace. A full list of topics covered in this episode includes: Current networking landscape What is eBPF? Traditional vs K8s networking K8s networking training/certification What networking changes mean for Cilium Mirantis k0rdent + Cilium partnership Future of networking (for AI/ML) If you want to listen to more episodes of Radio Cloud Native, please visit https://www.mirantis.com/radiocloudnative/ to download, or find them wherever you prefer to consume your podcasts.

All Infrastructure Is AI Infrastructure: Navigating the New Era of Enterprise AI at Scale

As enterprises scale generative AI and autonomous agents, every layer of the technology stack - from silicon to orchestration (ie. Metal to Model) - is being reshaped. In this episode, hosted by Mirantis CMO Dominic Wilde, you will hear why AI workloads reverse decades of cloud abstraction, what full-stack AI infrastructure actually demands (GPUs, CPUs, networking fabrics, power, storage, etc.), how data sovereignty and regulatory frameworks like GDPR and DORA create hard architectural requirements, and what principles - manageability, observability, flexibility, repeatability, and the importance of open infrastructure - must be used to guide enterprise AI platforms into the future. All of this change has informed how the teams at Mirantis built k0rdent, a complete, open source platform for AI infrastructure orchestration. A full list of topics covered in this episode include: The end of abstraction and what's next Full-stack AI infrastructure Data/AI sovereignty & compliance The developer experience gap Core principles for enterprise-ready AI platforms The case for open infrastructure Commoditization to contracts k0rdent by Mirantis If you want to listen to more episodes of Radio Cloud Native, please visit https://www.mirantis.com/radiocloudnative/ to download, or find them wherever you prefer to consume your podcasts.

Rancher Kubernetes Engine (RKE1) is EOL. So What's Next?

Rancher Kubernetes Engine 1 (RKE1) reached end of life on July 31st of 2025, meaning no more security patches, bug fixes, or a direct upgrade path forward. For businesses still running RKE1, the clock is ticking - and the decisions made now will have major implications for security, compliance, and operational continuity. In this episode, Edward Ionel of Mirantis is back to walk you through what re-platforming actually looks like in practice, the hidden costs and challenges of migration, and how to evaluate your options for moving to RKE2, RKE3, or a more modern Kubernetes platform. Whether you're managing 10 clusters or hundreds, this is a practical guide to navigating one of the most consequential infrastructure transitions your team may face. A full list of this episode's topics include: Official announcement of EOL for RKE1 Why migrating away from RKE1 doesn't work Current evolution in App infrastructure Current evolution of Cloud Common containerization challenges k0rdent by Mirantis Full container solution stack Value of the cloud native/K8s-first approach If you want to listen to more episodes of Radio Cloud Native, please visit https://www.mirantis.com/radiocloudnative/ to download, or find them wherever you prefer to consume your podcasts.

Stop Losing Money on Idle GPUs

The GPU cloud market is booming - but for NeoClouds and cloud service providers, explosive growth is quickly becoming a race to the bottom. In this episode, Edward Ionel of Mirantis breaks down why raw compute is no longer enough to sustain a profitable business, and what operators must do to protect their margins before the window closes. Edward walks through the full monetization maturity model - from commoditized bare metal to a fully managed AI factory platforms capable of delivering 50%+ profit margins - and explains why evolving from selling compute to selling outcomes is no longer optional. If you're building or operating GPU infrastructure, this episode is a must-listen. Reach out to Edward directly for a demo: eionel@mirantis.com A full list of this episode's topics include: Emerging GPU Cloud and AI Infrastructure opportunity Evolution and challenges for NeoClouds Transforming AI Services GPU depreciation gap and market erosion The 4 stages of GPU monetization Building an AI Service platform Building an AI Factory A hyperscaler-like experience for AI Real world case study If you want to listen to more episodes of Radio Cloud Native, please visit https://www.mirantis.com/radiocloudnative/ to download, or find them wherever you prefer to consume your podcasts.

Defeat Platform Complexity with Use Case-Optimized Multi-Cluster Kubernetes

In this month's installment, Sergey Goncharov, Sr. Product Manager for Mirantis Kubernetes Engine 4k (MKE 4k) is back to help you tackle the ever-emerging problem of Platform Engineering for complex multi-cluster, multi-cloud Kubernetes workloads. With the rise of AI/Ml, these are becoming more and more prevalent in enterprises around the world. Overcoming this complexity requires a multi-cluster approach: designing clusters tailored to specific workloads with declarative services and policies, ensuring consistent lifecycle management (LCM), and scaling this strategy across your environments. By optimizing platforms for specific use cases (Kubernetes-based platforms that is), you can improve agility, streamline operations, boost workload availability, enhance security, and maintain compliance - without implementing a global multi-cluster architecture at smaller scales. A full list of this episode's topics include: Challenges with Kubernetes complexity Multi-cluster thinking is key Building use case-optimzied platforms at scale Example open source tools for multi-cluster K8s If you want to listen to more episodes of Radio Cloud Native, please visit https://www.mirantis.com/radiocloudnative/ to download, or find them wherever you prefer to consume your podcasts.

Open Web Alliance Framework + amazee.io's Lagoon = Fully Open Source Web Hosting

In this month's installment of Radio Cloud Native, Bryan Gruneberg, Solutions Architect from amazee.io (now a Mirantis company), walks you through everything you need to know about the Open Web Alliance (OWA) and open source web hosting. He will cover some background in the beginning to set the stage for amazee.io's Lagoon, a fully open source application delivery platform built on top of Kubernetes - as well as amazee.io's tried and true open source website and AI hosting solutions. Bryan will cover, in detail, the framework laid out in the OWA's Open Web Manifesto, and how organizations can piggy-back on this structure to ensure that their hosting platform is just as open source as their solution. He will also look at the application side of things, exploring how platforms like Drupal, Wordpress, and TYPO3 stack up in comparison to the Open Web Alliance's standards and how you can leverage them in a truly open source, vendor-agnostic way. A full list of topics for this episode include: Background on amazee.io and Lagoon Background on the Open Web Alliance (OWA) Defining the "Open Web" via the OWA Open Web Manifesto How Lagoon maintains an "Open Web" Drupal vs Wordpress vs TYPO3 vs Joomla Why use Lagoon by amazee.io Resources for getting started with Lagoon If you want to listen to more episodes of Radio Cloud Native, please visit https://www.mirantis.com/radiocloudnative/ to download, or find them wherever you prefer to consume your podcasts.
