Absolutely keep your load balancer for multi-node scaling, but how are you going to run you WebAssembly workloads within a given node? Unit can do that.

Or what if you have a single logical service that's composed of a mix of Wasm endpoints and static assets augmenting a traditional Python application? Unit pulls that all together into a single, unified thing to configure and deploy.

If you're writing Node, Go, or Rust you haven't had to think about application servers for a long time. Folks writing Python and PHP still do, and WebAssembly will require the same supporting infrastructure since Wasm -- by definition -- is not a native binary format for any existing platform. :)
