Can You Maintain 1000 Apps? WasmCloud & K8s: The Ultimate Golden Template
Talkat KubeCon + CloudNativeCon Europe 2025 · on Thursday, 2025-04-03· at 15:00· Level 0 | ICC Capital Hall | Room I·
summary
Demonstrates that by replacing heavyweight container templates with a platform harness built on wasmCloud and Kubernetes, platform teams can manage 1,000 applications as a single patchable surface. Shows a working web shell exploit inside full OS containers, measures cold starts (1.2s vs milliseconds for warmed WASM), compiles user logic to 7 kilobyt components, runs 10,000 tiny components under 1GB, and plugs blob stores, HTTP, messaging and secrets as swappable capabilities.
