Get WITty: Evolving Kubernetes Scheduling With the WebAssembly Component Model - Dejan Pejchev & Jonathan Giannuzzi, G-Research
Thursday April 3, 2025 16:00 - 16:30 BST
Level 1 | Hall Entrance S10 | Room D
At KubeCon NA 2024, we introduced WASM + KWOK Wizardry: Writing and Testing Kubernetes Scheduler Plugins at Scale, showcasing how WASM plugins transform Kubernetes scheduling. This session continues the story, highlighting our progress toward a language-agnostic framework using the WebAssembly Component Model.

The current Go-centric WASM plugin SDK restricts innovation to a single language. By adopting the Component Model, we enable developers to write plugins in Rust, Python, JavaScript, and more, unlocking new possibilities. This approach enhances modularity, simplifies integration with standardized interfaces, and strengthens security through improved isolation.

We’ll also showcase how this aligns with the Kubernetes Scheduler Simulator, providing a powerful testing environment for these advanced plugins. Join us to see how the Component Model fosters collaboration, innovation, and extensibility in Kubernetes scheduling. Let’s move beyond wizardry and get truly WITty!
