Explore compiler and runtime co-design for WebAssembly-based Function as a Service (FaaS) in this 23-minute conference talk from KubeCon + CloudNativeCon Europe 2022. Delve into the potential of WebAssembly (Wasm) as a safe, portable, and efficient low-level code format for FaaS implementations. Learn about existing FaaS solutions, their challenges, and how compiler-runtime co-design can address these issues. Discover the benefits of compiling various source languages to Wasm and implementing fine-grained multi-tenancy. Gain insights into the future of FaaS and how Wasm is poised to become a dominant force in serverless computing.
