WasmEdge is already one of the smallest and most efficient Wasm runtimes out there. It embeds into libsql (SQLite on the server!) to execute user definited functions to perform complex tasks like HTTPS web services & AI inference from SQL statements! https://wasmedge.org/docs/embed/use-case/libsql/

The WasmEdge C++ and Rust SDKs allow host applications to embed Wasm functions asynchronously. It is critically important in many applications where the embedded Wasm function is simply not allowed to block the execution of the host applications. https://github.com/second-state/wasmedge-rustsdk-examples/bl...

Asynchronous host SDKs are complex and a lot of work still remains. We are continuously improving it with our end user and partner communities.

What's coming next?

* Support plugins in our Docker and k8s integrations

The example below, from the microservice-rust-mysql demo app, shows how to create a web server in hyper for WasmEdge. The main listening loop of the web server is as follows:

Hey Tim, I appreciate your willingness to engage. What I'm getting at is a bit more pointed. In terms of composability, Docker and WASM are opposites: Docker requires a stand-alone runtime, and an orchestration layer, etc., whereas a WASM module & runtime can be embedded directly into my application, into a browser, or into (comparatively) simple, time-tested tools like Apache[0].

So, to your point, the opportunity here is to provide WASM-native alternatives to existing container-specific technologies, that are more composable by design, because they don't have to deal with the complexity of trying to ape an extra operating system just to run some software.

For example, I'd love to see container orchestration be supplanted by something like a la carte Erlang-style service discovery—that's a primitive that could easily be composed with other primitives, and wouldn't result in the combinatorial explosion of nouns we see in systems like k8s / Swarm / others.
