WebAssembly: A Recovering Kubernetes Engineer's View of the Future
summary
Argues WebAssembly complements Kubernetes rather than replaces it and shows a working wasmcloud stack (using wasmcloud and Cosmonic) running a 49‑line Rust KV counter compiled to Wasm, linked at runtime to an HTTP provider and a Redis provider with zero code changes. Demonstrates moving the same module between a DigitalOcean K8s cluster and a laptop, routing across regions, and hot‑swap of backing stores; runtime supports thousands of modules per node and addresses bin‑packing and sandboxing use cases.
