KubeCon / CloudNativeCon Europe 2023

From April, 18th until Friday, 21st the KubeCon in combination with the CloudNativeCon took place in Amsterdam: COMMUNITY IN BLOOM. An exciting event for people with interest in Kubernetes and cloud native technologies.

At credativ, it is must to pre-train us in many relevant areas. This of course includes Kubernetes and Cloud Native technologies. The KubeCon/Cloud Native Con has been one of the conferences on our must-attend list for several years now.

A short diary

We started our journey to the KubeCon by Tuesday evening with the badge pickups. On Wednesday the Keynotes started with the usual welcome words and opening remarks.

The information that 10000 attendees have been registered with additional 2000 people on the wait list was really impressive and shows the importance of Cloud Native technologies. Nearly 58% of the attendees were new to the conference which proves that more and more people get in touch with Kubernetes and Co.

In addition to the common sponsored keynotes a short update of the CNCF graduated projects was presented. There was a wide variation of projects. From FluxCD to Prometheus, Linkerd, Harbor and many more.

The second day started once again with keynotes which included several project updates e.g. Kubernetes and incubating projects.

The last day as usual opened with keynotes. A highlight here was the presentation “Enabling Real-Time Media in Kubernetes” which gave some insights about a Media Streaming Mesh.

Supplemental to the talks and presentations some tutorials happened. Those tutorials usually take at least two time slots and therefore, provide a deeper insight into a specific topic and left room for questions. The tutorials we visited were well prepared and several people were cruising through the attendees to help and answer questions. One of those tutorials showed the usage and benefits of Pixie which provides deep insights into a system using eBPF and various open source projects.

Beyond the tracks a booth location was available, it has been divided (by halls) to the company related booths and an area with projects. NetApp was represented at several booths.

The main theme this year seemed to be all about eBPF and Cilium. Various presentations on different tracks highlighted this topic and showed areas of application for eBPF. Different Cilium talks presented various aspects of Cilium for e.g. observability or multi-cluster connections and application failover.

Not so good

One bad thing has to be mentioned. Some talks were full. Really full. To some of them we got no access due to the fact, that the room was filled 15-30 minutes before the talk started. Maybe it would be possible for the next time to ask all users to create a personal schedule in the corresponding app and reassign the rooms by the amount of interested (scheduled) people.

Keynotes, Talks and Presentations

A short overview about the (visited) highlights of the talks and presentations:

  • “Improve Vulnerability Management with OCI Artifacts – It Is That Easy” a great talk about images and artifacts related to trivy
  • “Anatomy of a Cloud Security Breach – 7 deadly sins” – a short recap of really occured security breaches. Nothing unknown but a good comprehension.
  • “Creating a Culture of Documentation” – about integrating the documentation process and creating a culture.
  • “Kubernetes Defense Monitoring with Prometheus” – an encouraging presentation about the usage of metrics
  • “Breakpoints in Your Pod: Interactively Debugging Kubernetes Applications” – a great talk about requirements and how to achieve debugging in pods
  • “Effortless Open Source Observability with Cilium, Prometheus and Grafana – LGTM!” Highlighting the observability features from Cilium and service dependency maps with Hubble.


As always, the conference was worthwhile for gaining new impressions, having exchange with interesting people and expanding one’s knowledge. We were certainly happy to participate are already looking forward to attending the next KubeCon.
