Aflevering #87 Beyond Containers: Webassembly In Kubernetes

?? Recorded during SRE Day in Amsterdam In this episode of the Dutch Kubernetes Podcast, Ronald Kers (CNCF Ambassador) and Jan Stomphorst (Solutions Architect at ACC ICT) sit down with Deepu K Sasidharan (Co-chair of JHipster) to explore a groundbreaking topic: running Kubernetes without traditional containers using WebAssembly (Wasm). ?? What is WebAssembly, and why should you care? Originally designed for running high-performance applications in web browsers, WebAssembly is now making its way into cloud-native computing and Kubernetes environments. Deepu explains how WebAssembly differs from containers and why it could be a game-changer for serverless computing and edge workloads. ?? Why WebAssembly in Kubernetes? ? Faster startup times – Near-instant execution compared to container cold starts. ? Lightweight execution – No OS dependencies, making it more efficient. ? Better security & isolation – Sandboxed execution with minimal attack surface. ? True serverless? – Potential for workloads that truly start and stop instantly. ?? Challenges & Limitations ?? Not every application can be easily ported – Multi-threading and TLS support are still evolving. ?? Standardization is still in progress – Different WebAssembly runtimes (e.g., WASI, Spin, WasmEdge) implement features differently. ?? Limited ecosystem adoption – Kubernetes and cloud providers are still building support for WebAssembly workloads. ?? What’s Next? As WebAssembly adoption grows, could it replace containers for certain workloads? Major cloud providers, Kubernetes distributions, and companies like Docker are investing in Wasm, but there’s still a long way to go before it becomes a mainstream alternative. ?? Is WebAssembly the next big thing in cloud-native computing, or just another niche technology? Listen to find out! ??
