Build a Serverless WebAssembly App in Python Using Spin

Overview

Explore the potential of WebAssembly in cloud computing through this conference talk from Conf42 Python 2024. Dive into the fundamentals of WebAssembly, its advantages, and its impact on serverless architecture. Learn about Spin, a tool for building and deploying WebAssembly applications, and witness two live demonstrations showcasing its capabilities. Discover how WebAssembly is revolutionizing cloud computing by eliminating the need for containers and addressing serverless limitations. Gain insights into the WebAssembly component model, module structure, and application composition. Understand the challenges and solutions for interpreted languages like Python in the WebAssembly ecosystem, including the use of componentize-py for seamless integration.
