How Small Can You Go? Customizing Interpreted Languages for WebAssembly Environments

Explore the customization of interpreters for popular language runtimes targeting serverless, embedded, and resource-constrained WebAssembly environments in this informative conference talk. Delve into the benefits of WebAssembly and WASI for developers and operations teams, including code reusability and enhanced security through sandboxing and capabilities-oriented security posture. Learn about the growing need to optimize deployment of traditional interpreted languages like Python, Ruby, and PHP in WebAssembly environments. Discover techniques for shrinking deployable modules, including interpreters and supporting libraries, as well as building bridges to access platform-specific functionality through host functions. Gain insights into current best practices and examine practical examples of running interpreted languages in popular serverless platforms. This 24-minute presentation by Rafael Fernandez Lopez from VMware and Oscar Spencer from Suborbital offers valuable knowledge for developers and operations professionals interested in optimizing interpreted languages for WebAssembly environments.
