Beyond the Limits: Scaling Kubernetes Controllers Horizontally - Tim Ebert, STACKIT
Thursday April 3, 2025 11:45 - 12:15 BST
Level 1 | Hall Entrance S10 | Room D
Do your Kubernetes controllers struggle to keep up with the demands of your growing infrastructure? As your clusters scale, traditional controller setups face increasing challenges, leading to slow reconciliation times, impacting application performance and overall cluster stability.

This session introduces sharding for Kubernetes controllers as a groundbreaking solution. By horizontally scaling controller workloads across multiple instances, it significantly improves scalability and addresses the inherent limitations of traditional leader election mechanisms.

In this session, we'll dive deep into the technical details of applying proven sharding mechanism from distributed databases to effectively partition controller workloads. We'll explore the underlying concepts and how to implement sharding in your own Kubernetes controllers.

Join us to learn how to overcome the scalability challenges of your Kubernetes controllers and unlock the full potential of your infrastructure.
