Serverless Functions with Zero Cold Starts: WebAssembly + Spin

Serverless doesn’t have to mean cold starts. Find the code over on GitHub at https://github.com/akamai-developers/serverless-url-shortener In this video, we build truly serverless functions with zero cold starts using WebAssembly (Wasm) and the CNCF Spin framework. Instead of relying on pre-warmed containers or microVMs, we use WebAssembly to achieve instant startup times and excellent runtime performance. You’ll learn: - Why WebAssembly is a game changer for serverless - How the CNCF Spin project works - How to build a real-world URL shortener as a serverless function - How to test everything locally - How to deploy globally on Akamai Cloud for ultra-low latency By running serverless workloads on Akamai’s massively distributed edge network, you can deliver fast, scalable APIs and functions close to your users—without worrying about cold starts ever again. If you’re a developer interested in serverless architecture, edge computing, WebAssembly, or cloud-native performance, this video is for you. New to Cloud Computing?
