KubeCon + CloudNativeCon Japan 2025

Our hero, a running app in a K8s prod environment, knows they are destined for greater things! They’re serving end users, but the value of the cloud is not realized. Hero’s devs toil on custom integrations, deployment is brittle and slow, and security and governance are HARD. Hero longs for a developer platform with consistent and repeatable system building blocks.

It is up to you, the audience, to guide our hero’s transformation from a lost and confused app to one built on a solid foundation that abstracts away complexity and promotes innovation. In their fifth KubeCon ‘Choose Your Own Adventure’-style talk, Whitney and Viktor will present choices that an anthropomorphized app must make as they build an Internal Developer Platform, enabling the devs to have self-service access to widely used system capabilities. Throughout the presentation, the audience (YOU!) will vote to decide our hero's path! Can we navigate CNCF projects and build a platform before the session time elapses?

Kubernetes cluster upgrades are frequent and can lead to unforeseen problems, including application downtime. Therefore, it is essential to understand the roles of each component that makes up a Kubernetes cluster and how they behave during an upgrade in order to safely upgrade the Kubernetes cluster and achieve zero downtime for your applications.

This session will explain the basics and practical practices to improve safety, and ensure zero downtime for your applications. In 30 minutes, we will provide an easy-to-understand explanation of everything from the roles of the main Kubernetes components to points to note during upgrades and recommended configurations to minimize or eliminate application downtime during the upgrade process. This session is recommended for those who are going to operate Kubernetes in earnest and those who are troubled by upgrades and want to learn how to prevent application downtime during Kubernetes cluster upgrades.

Join us on an anime-powered journey to explore the power of eBPF in cloud native. Inspired by Sailor Moon and Dragon Ball GT, this talk breaks down how eBPF enhances observability, networking, and security, using the Sailor Guardians and Gohan to make eBPF approachable. We’ll break down topics like real-time observability by comparing it to psychic flames.
And just as unchecked power in anime can lead to chaos, eBPF’s immense capabilities need to be used wisely. Drawing from Dragon Ball GT's arc where the Dragon Balls become a threat, we’ll examine best practices for safe deployment of eBPF (e.g., LSM, verifier constraints, Linux Capability restrictions). Spoiler alert: our Sailor Guardians and Gohan will come out victorious, worry not!

By the end, you’ll gain a clear understanding of how to wield eBPF safely and effectively in cloud native environments, no Super Saiyan transformation required!
