Leveling Up Wasm Support in Kubernetes
summary
Argues that WebAssembly becomes a third wave of cloud compute alongside VMs and containers, claiming half a millisecond cold start and orders-of-magnitude density gains (reporting 3,000 applications on a 2XL node after networking hacks). Describes building developer tools—Spin for two-minute from-cursor-to-deploy flows and test harnesses—and a Kubernetes integration (spin-kube) that runs WASM via containerd instead of reimplementing kube plumbing, and shows those pieces working in production-style tests.
