From hobby project to SaaS startup: Scaling Immich on Kubernetes to thousands of tenants by Jochem Bruijns

This talk takes you on my journey of building a cloud-native SaaS startup around Immich, the loved Google Photos alternative.
I’ll share the scaling challenges I ran into along the way, from design flaws to production bottlenecks, and how I solved them using CNCF projects like KEDA, ArgoCD, and others. You’ll hear about what worked, what didn’t, and the lessons I learned so you don’t have to make the same mistakes.

From Chaos to Calm: EoCs at work by Riccardo Trivellato

In this talk, I’ll walk you through how our GitLab Dedicated team (handling single-tenant customers) dealt with a constant flood of Sidekiq alerts that made life really hard for our on-call engineers. Since we work fully async—no meetings, everything documented in writing—we had to find a smart, clear way to tackle the problem.
Embracing a dogfooding mindset, we turned these challenging incidents into valuable learning experiences. The solution wasn’t a quick fix but an ongoing, iterative process: we studied Sidekiq more deeply, especially in our unique GitLab setup, and restructured queues by splitting them into separate pods based on priority. This approach boosted efficiency, cut unnecessary costs with smarter scaling, and made on-call life much easier.
If you’re interested in how to transform messy problems into continuous improvement without endless meetings, this talk is definitely for you!
