Scalability related queries for the self-hosted Prefect-2.0 API Server

I want to know how the self-hosted prefect-2.0 api server scales vertically and horizontally. Assuming I’m using a PostgreSQL db following are my queries:

  1. Does the server scale vertically with multiple cpu cores? ( assuming Yes since it is RESTful and thus stateless b/w requests )
  2. How memory intensive is the server? ( How much memory would a server need to handle a constant load of 100RPS without issues )
  3. Does the server scale horizontally on multiple VMs / k8s cluster? ( also assuming Yes since it is RESTful )
