This talk will explore how to customize interpreters for popular language runtimes to target serverless, embedded and resource-constrained WebAssembly environments. WebAssembly and WASI bring many benefits to developers and operations teams. The former are able to reuse their code with no or minor adaptations, whereas the latter can deploy on safer environments, thanks to sandboxing features and a capabilities-oriented security posture. As WebAssembly becomes popular among traditional interpreted languages such as Python, Ruby and PHP there is a growing need to optimize their deployment. This involves both shrinking the size of the deployable modules, including the interpreter and supporting libraries, as well as building bridges to access platform-specific functionality that needs to be exposed to the developer, typically via host functions. This talk will provide an overview of current best practices and provide practical examples of running interpreted languages in popular serverless platforms.
