KubeCon + CloudNativeCon Japan 2025

Everyone is talking about platform engineering. You see smooth demos of golden paths and self-service platforms. However, there’s a significant area of challenges that is less talked about and thus often neglected when designing developer platforms.

In this talk, we’ll explore the often-overlooked day 2 challenges that platform teams face. We’ll dissect the area of day 2 into the many sub-areas and challenges they pose. Drawing on real-world experiences, including notable migrations that many in this community have faced, we'll shed light on the pain behind developer platforms and discuss solutions to these issues. Among others, we’ll delve into practical strategies for managing versioning and rollouts, and highlight the significant hurdles encountered, such as dependencies on end user teams or GitOps.

Join us for insights, strategies, and stories from the trenches that will help you navigate the complexities of service iteration in developer platforms.
