From Cloud to Edge computing - Unleashing the power of WebAssembly at the edge by Alex Casalboni

Wasm I/O 2025 - Barcelona, 27-28 March Slides: https://2025.wasm.io/slides/from-cloud-to-edge-computing-unleashing-the-power-of-webassembly-at-the-edge-wasmio25.pdf As cloud computing reshapes traditional backend architectures, emerging demands for ultra-low latency and data locality reveal its limits. Enter edge computing—where WASM serves as a critical bridge between centralized cloud capacity and the need for distributed processing. In this session, we’ll dive deep into how WebAssembly enables lightweight, secure, and fast compute workloads at the edge, with an emphasis on real-world use cases that leverage Rust’s unique strengths for predictable performance and memory safety, while coexisting with cloud resources. We’ll showcase the architectural tradeoff and technical challenges we face at Edgee such as data sovereignty and security constraints to power features such as data collection and dynamic A/B testing. We’ll share how we optimized our open-source Rust-based WebAssembly components for edge deployment. Join us to discover how to build architectures that seamlessly blend cloud and edge, unlocking a new level of responsiveness and efficiency.
