    #131 Securing the Software Supply Chain in Kubernetes

    In this episode, Ronald and Jan talk with Zahra Dehghanpour (platform engineer at bol.com) and Feike Wierda (Senior DevOps Engineer @Bol. via HCS Company) about software supply chain security in Kubernetes environments. Zahra shares her journey from development to platform engineering, driven by the constant challenges and unpredictability of working with infrastructure. Her earlier experience working in Iran, where infrastructure had to be built and maintained under constraints, shaped her approach to designing resilient and fault-tolerant systems. Feike explains that software supply chain security covers everything that touches your software, from dependencies and tooling to people and processes. At bol.com, this is addressed by standardizing pipelines, controlling dependencies through internal repositories, and applying security scanning early in the process. A key theme is balance: developers need freedom, but within secure guardrails. That’s why pipelines are not immediately blocked on vulnerabilities, but first used to provide visibility and gradually increase maturity. The episode also highlights that security is never “done.” It’s an ongoing process where automation, better tooling, and AI will play an increasingly important role, especially in areas like code review and vulnerability management.

    #130 What If You Never Had to Patch CVEs Again?

    In this episode, Ronald and Jan are joined by Hannah Hawken, partner sales at Chainguard,  who brings a fresh perspective on something every Kubernetes team struggles with: security. What starts as a conversation about career paths quickly turns into a deeper discussion about how we’ve been approaching security all wrong for years. Coming from a background in development and later moving into security, she reflects on what it feels like to build software without truly understanding the risks—and why so many teams are still in that exact position today. Instead of reacting to vulnerabilities after they appear, the conversation explores a different mindset. One where security isn’t something you bolt on later, but something you start with. Not “shift left”… but start left. From there, the discussion moves into the reality many teams face: thousands of CVEs, endless patching cycles, and security teams constantly playing catch-up. What if that entire model could be flipped? What if the software you build on is already secure by design? That idea opens the door to a broader conversation about trust in open source, the hidden complexity of dependencies, and the trade-offs between speed and security. Along the way, Ronald and Jan challenge what this means in practice. How do you actually adopt a different approach? What changes for developers? And where does this fit in real-world environments? The episode also touches on the future. Not just of Kubernetes, but of the infrastructure powering AI and modern applications. Because if workloads are becoming more complex and critical, the foundation they run on needs to evolve as well. By the end, one thing becomes clear: security isn’t just a step in the process anymore… it’s becoming the starting point Stuur ons een bericht.

    #129 AI, Legacy en de Illusie van Modernisering

    In aflevering 129 spreken Ronald en Jan met Jan Buurman van HCS Company iemand die al sinds zijn 17e in de IT zit en de evolutie van mainframes tot Kubernetes van dichtbij heeft meegemaakt  Jan begon als COBOL-programmeur en groeide door richting organisatie, processen en platformstrategie  Vanuit die brede ervaring kijkt hij anders naar Kubernetes dan veel engineers: niet als eindoplossing, maar als onderdeel van een groter geheel. Een van de scherpste inzichten uit het gesprek: Veel organisaties draaien al vijf jaar Kubernetes, maar hebben vaak nog maar 5–10% van hun applicatielandschap gemoderniseerd  Volgens Jan ligt het echte probleem niet bij het platform, maar bij legacy-applicaties en de businesscontext eromheen. Hij deelt een confronterende anekdote van een overheidsorganisatie waar Kubernetes technisch succesvol was geïmplementeerd, maar het onderliggende probleem niet oploste, omdat de oude COBOL- en Oracle Forms-applicaties nog steeds herbouwd moesten worden  We praten over: Waarom platform engineering niet automatisch modernisering betekentDe kloof tussen “de bubbel” en de realiteit bij developers buiten de cloud-native wereld Community-denken binnen organisaties als versneller voor standaardisatie  AI als mogelijke katalysator om legacy sneller te migreren naar Kubernetes  En waarom standaardisatie vaak het ondergeschoven kindje blijft  Jan sluit af met een nuchtere blik op de toekomst van Kubernetes: niets is permanent in IT. Ook Kubernetes zal ooit verdwijnen — maar tot die tijd is het dé standaard  Een aflevering over realisme, organisatieverandering en waarom techniek zelden het echte probleem is.

    #128 Why “Just Give Me Admin” Is the Most Dangerous Request in IT

    In this episode of The Dutch Kubernetes Podcast, Ronald and Jan are joined by Maurice Côté, VP of Products at Devolutions, to talk about one of the most misunderstood topics in modern IT security: Privileged Access Management (PAM). Too often, PAM is treated as a compliance checkbox. Something you buy because an auditor, insurer, or regulation tells you to. Maurice explains why that mindset is dangerous — and why access itself has become one of the biggest attack surfaces in today’s infrastructures. The conversation explores how Zero Trust principles apply in real-world environments, including Kubernetes and DevOps workflows. Topics include least privilege, just-in-time access, identity-based authentication, service accounts, and why traditional passwords are slowly disappearing in favor of certificates, passkeys, and identity providers. They also discuss upcoming regulations like NIS2 and DORA, and why security isn’t about passing audits, but about being able to survive, recover, and continue operating when something goes wrong. From bastion hosts and privileged access workstations to secret rotation and Kubernetes-native integrations, this episode focuses on practical security — not buzzwords. The key takeaway is clear: Security is not a product you buy once. It’s a discipline you practice continuously. A must-listen episode for platform engineers, DevOps teams, security architects, and anyone working with Kubernetes in regulated or high-risk environments. Powered By ACC ICT Stuur ons een bericht.

    #127 From Silicon Valley to Palestine: Scaling Software Globally

    In this episode of The Dutch Kubernetes Podcast, Ronald and Jan talk with Yahya Al-Salqan, CEO and co-founder of Jaffa.Net Software, about building and scaling global software companies far beyond the traditional tech hubs. Yahya shares his personal journey from academia and Silicon Valley, where he worked at Sun Microsystems, back to Palestine to found Jaffa.Net. What started as a mission-driven decision to contribute to his community has grown into a company with over 26 years of experience, serving international clients such as Intel, BMW, Fujitsu, Lufthansa, Oxford University, and several Dutch organizations. The conversation explores how modern software engineering practices and cloud-native technologies make it possible to deliver enterprise-grade solutions globally. Kubernetes and container technologies play a key enabling role by providing consistent environments, repeatable deployments, version control, and zero-downtime upgrades for customers running ERP and custom software solutions. Beyond technology, the episode highlights the Palestinian IT ecosystem, the importance of education, and how software development allows talent to transcend physical and political borders. Yahya explains why the IT sector is one of the fastest-growing contributors to the local economy and why investing in people and skills is the most sustainable path forward. The discussion also touches on future trends such as AI, blockchain, and programmable digital money, and how companies must continuously evolve to stay relevant. Throughout the episode, one theme remains central: global software scale is no longer defined by geography, but by mindset, tooling, and execution. Powered by ACC ICT Stuur ons een bericht.

    #126 From 135 ms to 6 ms: The Multi-Cloud Networking Mistake Everyone Makes

    In episode 126 of De Nederlandse Kubernetes Podcast, Ronald and Jan sit down with Chris Noon, Technical Solution Director at Alkira, to talk about one of the most underestimated challenges in cloud-native environments: networking. Chris shares his journey from traditional telco and enterprise networking, through VMware NSX, to modern cloud and Kubernetes platforms. The conversation dives deep into why networking often becomes more complex—not less—once organizations adopt multi-cloud, hybrid cloud, and Kubernetes at scale. Key topics include: Why IPsec meshes don’t scale in multi-cloud environmentsHow “hair-pinning” traffic across regions creates massive latencyAlkira’s cloud-native approach to connecting AWS, Azure, GCP, and on-premNetworking considerations around Kubernetes, CNI’s, and Zero TrustDORA compliance, security architecture, and data sovereigntyWhy AI workloads make networking and data placement more critical than everA great episode for anyone who realizes that cloud-native doesn’t end at Kubernetes—it starts with solid network architecture.

    #125 Why Kubernetes Belongs on Raspberry Pi’s, PLCs, and the Edge

    In this episode of The Dutch Kubernetes Podcast, Ronald and Jan sit down with Jussi Nummelin, Senior Principal Engineer at Mirantis, to explore the world of lightweight Kubernetes, edge computing, and multi-cluster orchestration. Jussi introduces k0s, a fully upstream Kubernetes distribution packaged as a single, statically compiled binary with zero dependencies. He explains why simplicity, predictability, and minimal operational overhead are essential for edge and IoT environments such as factory floors, industrial controllers, and remote locations with limited connectivity. The conversation then moves to K0rdent, Mirantis’ multi-cluster management layer built on top of Cluster API. K0rdent enables organizations to declaratively manage large numbers of clusters while automatically deploying essential “beachhead services” like CNI, storage, and observability across environments. Finally, Jussi shares his perspective on the future of Kubernetes: why it’s here to stay, how edge and cloud are converging, and why Kubernetes is becoming the standard orchestration layer far beyond the traditional datacenter. A practical and forward-looking episode packed with real-world use cases, architectural insights, and a clear vision of where Kubernetes is heading. Stuur ons een bericht.

    #124 Van Image Max Age tot DRA: de praktische kant van Kubernetes 1.35

    In aflevering 124 van De Nederlandse Kubernetes Podcast bespreken Jan Stomphorst en Ronald Kers de nieuwste Kubernetes-release: versie 1.35. Dit keer geen volledige lijst met alle wijzigingen, maar een bewuste keuze voor impactvolle features die in de praktijk het verschil maken. Een van de eerste onderwerpen is Image Max Age, een nieuwe kubelet-optie waarmee je expliciet kunt bepalen hoe lang ongebruikte container images op nodes blijven staan. Dit helpt bij het voorkomen van volle disks, onverwachte opruimacties en onnodige image downloads, vooral in grote clusters. Daarna komt Max Parallel Image Pulls aan bod. Deze feature voorkomt zogeheten image pull storms wanneer veel nodes tegelijkertijd een nieuwe image moeten downloaden. Door het pullgedrag te limiteren, blijven clusters stabieler en worden registries minder zwaar belast. Ook Dynamic Resource Allocation (DRA) krijgt aandacht. Hiermee kunnen resources buiten CPU en geheugen, zoals GPU’s en andere gespecialiseerde hardware, beter en veiliger worden toegewezen aan workloads. Kubernetes 1.35 voegt bovendien verbeterde foutmeldingen toe, waardoor het veel duidelijker wordt waarom een workload niet start. Tot slot bespreken Jan en Ronald verbeteringen rond StatefulSets, waaronder meer controle over parallelle updates. Dit maakt updates van databases en andere stateful workloads sneller en beter voorspelbaar. Kortom: Kubernetes 1.35 laat zien dat de focus steeds meer ligt op stabiliteit, schaalbaarheid en real-world operaties, in plaats van alleen nieuwe features toevoegen. Stuur ons een bericht.
