The post covers two patterns: monolithic operators where SDK integration and business logic coexist in one module, and composed operators that use WIT interfaces to separate SDK integration from business logic across independently developed components. The Component Model enables fusing these components via `wasm-tools compose`, while WASI Preview 2 provides standardized system APIs. Graph definitions in YAML decouple pipeline structure from infrastructure binding, allowing the same operators to deploy across environments without rebuilds. Compiled WASM modules and graph definitions are stored as OCI artifacts in a container registry. ## Full article daily.dev links to this article rather than hosting it.
