Faasm Ecosystem

Faasm is a research project on distributed serverless runtimes with WebAssembly (WASM). Faasm originated in the Large-Scale Data & Systems group from the Imperial College London, but has contributors and collaborators among other institutions.

Faasm Projects

• Faasm is a high-performance serverless runtime using WebAssembly for function isolation.
• Faabric is a messaging and state layer for distributed serverless applications.
