Inside KubeCon Europe 2025
Luca Berton attended KubeCon Europe 2025 in London, sharing real-time insights into one of the world’s most vibrant gatherings of Kubernetes and cloud-native professionals.
From riding the Kube Train to the talks on infrastructure as code and automation in Kubernetes environments, Luca documented it all — so you don’t miss a beat.
KubeCon + CloudNativeCon Europe 2025 at ExCeL London
KubeCon + CloudNativeCon Europe 2025 ran from 1 to 4 April at ExCeL London. Tuesday 1 April was the co-located day, and the main conference ran Wednesday to Friday. This page started as a set of video blurbs. The photos taken in the halls have since been written up as separate posts, day by day, and the photos below show the venue.

The talks, day by day
- Tuesday 1 April, co-located day. Platform Engineering Day: the abstraction debt trap covers a platform quiz, tiered abstractions and policy guardrails. DRA GPU sharing and CERN’s Kubeflow ML challenges covers the NVIDIA DRA driver examples and a platform that scores ML submissions as pipelines.
- Wednesday 2 April. Keynote slides, a kernel lockup postmortem and production safety rules covers CNCF at ten years, the CNPA certification and a Fastly talk with the 1-2-24 blast radius rule.
- Thursday 3 April. Benchmarking AI and GPU workloads with Triton compares time-slicing and MPS GPU sharing. Kubernetes at scale with LinkedIn and New Relic starts with LinkedIn’s bare-metal platform and 5,000-node clusters.
- Thursday keynote. The ICC Auditorium keynote block included a sponsored keynote, Redefining MLOps at Scale on Top of Kubernetes, by Randy Bias, Vice President of Open Source Strategy & Technology at Mirantis, as the official schedule lists it. The stage screens showed his name and title, and my recording catches the live demo: the Mirantis and Gcore stack was used to stand up an inference instance running a small open model in minutes, as a way to argue that the hard problem is managing Kubernetes sprawl as AI-powered apps multiply.
- Interviews across the three days. Twelve short on-camera conversations with Red Hat, Trilio, vCluster, Cloudsmith, Coder, Kubeflow, KitOps, Qodo and CNCF community people.
- The week after. The Dutch Cloud Native recap meetup on 10 April covered Nutanix’s air-gapped bootstrap design and AWS’s Triton on EKS pattern.
- Friday 4 April. The same Kubernetes at scale post ends with New Relic’s cell-based multi-cloud design using Cluster API and Karpenter.
My takeaways a few days later
When I recorded my own recap clips afterwards, the points I kept returning to were these. London felt like the centre of cloud native for the week, with around 15,000 attendees, plus many side events and branded breakfasts. AI dominated the programme, including agentic and generative AI, and my argument was that Kubernetes is a natural home for it because inference needs scalable, flexible infrastructure and the DevSecOps practices we already use for software can be applied to models. What surprised me most was how much attention observability and OpenTelemetry got, for the same reason. The talks were recorded, so you can catch up on the CNCF YouTube channel.

What Stood Out
- AI & Kubernetes: An ongoing theme throughout the conference.
- Infrastructure as Code: scaling automation inside Kubernetes environments was a recurring theme.
- Community: From Ansible contributors to DevOps engineers, the energy was real.
- The Kube Train: Yes, it’s a thing — and yes, it was as geeky as it sounds.
Final Thoughts
Whether you’re into containers, clouds, or community, KubeCon 2025 delivered.
And Luca captured it with enthusiasm, insight, and just enough behind-the-scenes action to make you feel like you were there too.
