The MonkCast: WASM and Edge Compute

WebAssembly enables sub-millisecond cold starts for serverless functions, solving the performance penalty that forces teams to keep containers warm in traditional platforms like AWS Lambda. Combined with edge networks that reduce network latency to 7-10ms, this delivers true pay-per-use serverless without sacrificing user experience. Spin, a CNCF project, provides a developer-friendly runtime that mirrors familiar language APIs while enabling hybrid architectures mixing WebAssembly functions with containerized workloads. Real-world applications include edge authentication, geographic content decisions, and ad injection for streaming platforms.
