Why can the Backstage frontend and backend be scaled independently?

Because the frontend is serverless and the backend is static.

Because they are separate components that communicate over a network.

Because the backend is a database and the frontend is a web server.

Because they are bundled together in a single deployment unit.

How does the Backstage frontend typically communicate with the backend to fetch data?

By using server-side includes to embed data into the HTML.

WebSocket connection for push updates

How is the Backstage frontend typically deployed?

As a containerized application that runs on a Kubernetes cluster.

As a virtual machine image that includes the backend and frontend together.
