-# Fluence Compute Engine

-[Fluence Compute Engine](https://github.com/fluencelabs/fce) \(FCE\) is a general purpose WebAssembly runtime that could be used in different scenarios, especially in programs based on the [ECS](https://en.wikipedia.org/wiki/Entity_component_system) pattern or plugin architecture. It runs multi-module Wasm applications with [interface-types](https://github.com/WebAssembly/interface-types/blob/master/proposals/interface-types/Explainer.mdhttps://github.com/WebAssembly/interface-types/blob/master/proposals/interface-types/Explainer.md) and [shared-nothing](https://en.wikipedia.org/wiki/Shared-nothing_architecture) linking scheme.

+# Marine

+[Marine](https://github.com/fluencelabs/marine) is a general purpose WebAssembly runtime favoring Wasm modules based on the [ECS](https://en.wikipedia.org/wiki/Entity_component_system) pattern or plugin architecture and uses Wasm [Interface Types](https://github.com/WebAssembly/interface-types/blob/master/proposals/interface-types/Explainer.mdhttps://github.com/WebAssembly/interface-types/blob/master/proposals/interface-types/Explainer.md)  \( IT\) to implement a [shared-nothing](https://en.wikipedia.org/wiki/Shared-nothing_architecture) linking scheme. Fluence [nodes](https://github.com/fluencelabs/fluence) use Marine to host the Aqua VM and execute hosted Wasm services.

+Todo: we could really do with diagram

+The  [Marine Rust SDK](https://github.com/fluencelabs/marine-rs-sdk) allows to hide the IT implementation details behind a handy procedural macro `[marine]` and provides the scaffolding for unit tests.

 # Marine CLI
 
-The [Marine command line tool](https://github.com/fluencelabs/marine) provides the project `marine build` functionality, analogous to `cargo build`,  that results in our Rust code to be compiled to the _wasm32-wasi_ module. In addition,  `marine` provides utilities to inspect Wasm modules, expose Wasm module attributes or manually set module properties.
