Based on the experiences of the two speakers—one working in a large corporate environment striving to foster Wasm adoption internally, and the other from a small startup focused on building better tooling for the Wasm ecosystem—this talk explores the hurdles and opportunities in establishing Wasm’s place, on the server side, across diverse contexts. We’ll analyze the key requirements necessary to make Wasm a mainstream technology on the server side, focusing on the following topics: -The current state of the System Interface (WASI) -Debugging tools for server-side Wasm -Monitoring and observability practices -Package management challenges -Secure supply chain requirements -Join us as we explore the evolving landscape of server-side WebAssembly and its potential to transform backend development.
