Scalability Questions

Hi, I'm building an app which handles some reasonably intensive requests on the server (pupetteer headless + LLMs + image editing etc). I'm not sure how wasp (wasp open saas specifically) will handle multiple concurrent requests. Would it be better to host these processes in a separate docker container, scale horizontally and make requests to the containers? From the documentation, I'm struggling to understand exactly how the applications are deployed. I know how to do it with the CLI tools, but I don't know what the architecture looks like and what these limitations would be.
