WebAssembly Modules

Ocre containers use WebAssembly (WASM) modules as the format for executable code. These modules are stateless binaries compiled to run on the WASM virtual machine.

Modules can either be pure WebAssembly or Ahead-of-Time (AOT) compiled binaries optimized for a specific platform target. In general, the Ocre Orchestration Hub will automatically AOT compile modules on-demand based on the architecture of the deployment target. However, there are instances where a pure WASM binary may be preferred.

Currently, only a single WASM module is supported per container image. However, we are exploring extending this to support multiple modules and/or components via the WebAssembly Component Model.
