• #122: Helm, Hiccups, and High Scale: Adobe’s Kubernetes Story

  In deze aflevering spreken Ronald en Jan met Giorgia Fiscaletti, Cloud Reliability Engineer bij Adobe. Giorgia vertelt hoe ze vanuit een creatieve achtergrond — kunst en digital design — uiteindelijk in de wereld van cloud engineering en Kubernetes terechtkwam.Bij Adobe werkt Giorgia aan Adobe Experience Manager, een enorm platform dat draait op tientallen Kubernetes-clusters met honderden namespaces per cluster. Ze deelt hoe Adobe Helm inzet voor het managen van applicaties op schaal en welke uitdagingen daarbij komen kijken.Belangrijkste inzichten uit het gesprek:Van creatieve roots naar cloud engineering: Een onverwachte maar krachtige overgang van artistieke studies naar high-scale cloudplatforms.Helm op massale schaal: Adobe gebruikte aanvankelijk per namespace een eigen helm-controller en source-controller, maar bij clusters met 200–300 namespaces leidde dit tot overbelasting van de API-server.Sharding als oplossing: Door controllers te centraliseren en te sharden over labels werd de druk op de API-server drastisch verlaagd.Etcd-problemen: Helm release secrets stapelden zich op, wat clusters richting read-only situaties duwde. Giorgia legt uit hoe dit werd geïdentificeerd en verholpen.Complexe customization-lagen: Adobe combineert Helm met meerdere configuratielagen voor klantomgevingen, interne features en experimentele patches.Real-world scale: 50+ clusters, ~200 namespaces per cluster, Argo CD pipelines, Flux controllers en zeer diverse klantconfiguraties — allemaal parallel draaiend.Werken bij Adobe: Giorgia geeft een uniek inkijkje in de tooling, architectuur en cultuur achter een platform waar duizenden engineers op bouwen.Deze aflevering biedt een zeldzaam kijkje in de schaalproblemen, designkeuzes en technische creativiteit die nodig zijn om Kubernetes in enterprise-omgeving zoals Adobe soepel te laten functioneren.Powered by ACC ICTStuur ons een bericht.ACC ICT Specialist in IT-CONTINUÏTEIT Bedrijfskritische applicaties én data veilig beschikbaar, onafhankelijk van derden, altijd en overalSupport the showLike and subscribe!

• #121 SBOM or Be Doomed: Surviving the Next Supply-Chain Meltdown

  In this episode of The Dutch Kubernetes Podcast, Ronald and Jan sit down with Soroosh Khodami to explore one of the most urgent questions in modern software engineering: are we truly ready for the next Log4Shell-level cyber crisis?Soroosh, a hands-on solution architect currently supporting security platform services at Rabobank, takes us deep into the evolving threat landscape. From classic vulnerabilities like SQL injection to modern supply-chain attacks and the infamous XZ backdoor, he explains how seemingly small weaknesses can cascade into full-cluster compromise — especially in cloud-native and Kubernetes environments.The conversation covers:How a simple SQL injection can escalate into full Kubernetes root access, thanks to lateral movement and unpatched dependenciesWhat supply-chain attacks really are, and why they’re becoming the attackers' favorite weaponLow-effort, high-impact practices to secure your CI/CD pipelineShift-Left Security & DevSecOps — what’s hype, what’s real, and how teams need to evolveWhy SBOMs are becoming mandatory, and how they help organizations prepare for future zero-daysEssential tooling for SBOM generation, scanning and continuous monitoringHow new EU regulations (DORA & CRA) will impact developers, architects and enterprises in the coming yearsSoroosh also shares practical stories from the field, including real-world examples of dependency attacks, insecure pipelines, and security mistakes that happen even in mature organizations.This episode is a must-listen for developers, architects, platform engineers, and anyone building or deploying software in 2025 and beyond.Stuur ons een bericht.ACC ICT Specialist in IT-CONTINUÏTEIT Bedrijfskritische applicaties én data veilig beschikbaar, onafhankelijk van derden, altijd en overalSupport the showLike and subscribe!

• #120 Let Them Cook — Inside the Kubernetes Recipes Cookbook

  In this episode, we sit down with Luca Berton and Grzegorz (Greg) Stencel, authors of the brand-new book Kubernetes Recipes — a 400+ page cookbook packed with real, practical solutions for everyday Kubernetes challenges.Luca and Greg explain how the idea for the book started: most Kubernetes books do a great job explaining theory, but very few show how to solve the messy, real-world issues engineers actually face. So instead of writing “yet another reference manual,” they chose the cookbook format: 👉 a problem, 👉 a clear solution, 👉 and deeper explanations when needed.We discuss:How they co-wrote the book late at night while balancing work, family life, and open source contributions.Why enterprise Kubernetes, especially in heavily regulated environments like finance, is a completely different beast.How their recipes cover everything from beginner topics to advanced CRDs, operators, networking, storage, NFS, stateful apps, and multi-cloud clusters.The tools that actually help developers — from KubeLens to vCluster.Why writing a book forces more accuracy and consistency than video tutorials.How they used real questions (including many from Stack Overflow) to choose the most relevant scenarios.We also talk about the future of Kubernetes:Luca sees AI workloads, better observability, and complexity-reducing tooling as the next big wave.Greg stresses that developer experience must improve — especially for developers suddenly expected to “learn Kubernetes” overnight. And yes, cluster upgrades remain painful.A fun and insightful conversation about practical Kubernetes knowledge, open source culture, and what engineers actually need today.Stuur ons een bericht.ACC ICT Specialist in IT-CONTINUÏTEIT Bedrijfskritische applicaties én data veilig beschikbaar, onafhankelijk van derden, altijd en overalSupport the showLike and subscribe!

• #119 Your Web App Scaling Tricks Don’t Work for LLMs

  In this episode, we talk with Abdel Sghiouar and Mofi Rahman, Developer Advocates at Google and (guest) hosts of the Kubernetes Podcast from Google. Together, we dive into one central question: can you truly run LLMs reliably and at scale on Kubernetes?It quickly becomes clear that LLM workloads behave nothing like traditional web applications:GPUs are scarce, expensive, and difficult to schedule.Models are massive — some reaching 700GB — making load times, storage throughput, and caching critical.Containers become huge, making “build small containers” nearly impossible.Autoscaling on CPU or RAM doesn’t work; new signals like GPU cache pressure, queue depth, and model latency take over.LLMs don’t run in parallel, so batching and routing through the Inference Gateway API become essential.Device Management and Dynamic Resource Allocation (DRA) are forming the new foundation for GPU/TPU orchestration.Security shifts as rootless containers often no longer work with hardware accelerators.Guardrails (input/output filtering) become a built-in part of the inference path.And then there’s the occasional request from customers who want deterministic LLM output — to which Mofi dryly responds: “You don’t need a model — you need a database.”Powered by: ACC ICTStuur ons een bericht.ACC ICT Specialist in IT-CONTINUÏTEIT Bedrijfskritische applicaties én data veilig beschikbaar, onafhankelijk van derden, altijd en overalSupport the showLike and subscribe!

• #118 Why Ceph Still Rules Cloud-Native Storage

  In this episode of De Nederlandse Kubernetes Podcast, we talk with Travis Nielsen, one of the original creators of the Rook project, about the evolution of cloud-native storage and how Rook and Ceph make reliable, distributed storage accessible to Kubernetes users.Travis shares the story of how Rook started back in 2016 when Kubernetes was still young and how it became the bridge that made Ceph, a powerful but complex storage system, usable in the cloud-native era.We discuss:What Ceph actually is and why it remains one of the most trusted open-source storage platforms.How Rook simplifies Ceph deployment and management inside Kubernetes clusters.The difference between NFS and CephFS, and when to use each.The best ways to run databases on Ceph and how to balance performance, consistency, and replication.Multi-tenancy, scaling, and failure domains  how Ceph handles massive distributed systems.Common mistakes people make when setting up Ceph and how to avoid them.The future of storage in the Kubernetes ecosystem and why Ceph remains essential for stateful workloads.A deep dive into the intersection of data durability, Kubernetes, and open source innovation  from someone who helped build it all.Stuur ons een bericht.ACC ICT Specialist in IT-CONTINUÏTEIT Bedrijfskritische applicaties én data veilig beschikbaar, onafhankelijk van derden, altijd en overalSupport the showLike and subscribe!
