We need a proxy like nginx or envoy to communicate the cloud system with the exterior while load-balancing resources.

For the heavy task, we may want to use WebAssembly so we can use almost the same (native) code in the cloud nodes and in the user browser as well as achieving a better performance than using JS alone in the browser.

The problem with using WebAssembly only in the browser is the (efficient) communication between the browser and the cloud. We can address this problem by:

1. Use HTTP to communicate and use JSON as a way to communicate nodes. Easy to implement.
2. User GRPC and Protocol Buffers to communicate between nodes. To do that, we will need to use JS to retrieve the response from the webassembly execution and then send it over grpc.

It seems that GRPC is not supported in Go over WebAssembly, but, this repo seems to solve it: https://github.com/johanbrandhorst/grpcweb-wasm-example.
