What should be done before upgrading a production Backstage instance?

Disable monitoring to avoid false alerts

Take a backup of the database and configuration

A company runs Backstage in production with multiple backend replicas behind a load balancer. They need to upgrade Backstage to a new version that includes database migrations. The company requires minimal downtime. What is the best upgrade strategy?

Update the backend replicas first, then run the migrations.

Stop all backend replicas, run the migrations, and then start the new version.

Run the database migrations first, then perform a rolling update of the backend replicas.

Run the migrations and update the replicas simultaneously in the same deployment step.

A company is deploying Backstage to production. They plan to serve the frontend from a CDN and the backend from a container orchestration platform. The security team requires that all traffic between the user's browser and both the frontend and backend be encrypted. What is the minimum configuration to achieve this?

Use a VPN for all users to access the frontend and backend.

Enable HTTPS on the backend container directly by installing a TLS certificate inside the container.

Terminate HTTPS at the CDN for the frontend and at the load balancer for the backend, and ensure the backend's base URL uses HTTPS.

Terminate HTTPS only at the CDN for the frontend, and keep the backend on HTTP because it is internal.
