I’m having trouble thinking of a better way to handle file downloads in a micro-services architecture.

We have a micro-service that generates a report and sends the download url to the results micro-services like so:

{
...,
id: "056b99d5-5983-4e63-8eb4-ccccc46c10b7",
report_download_url:"https://reporter-api.staging.services.com/reports/22f6bdc8-1c64-4c378018-47579d1b369b/download",
...
}

The results microservice frontend directly calls the reporter service to download the file using that url. This feels slightly weird to me. Should the report micro-service be sending a url pointing towards the report service or maybe the S3 bucket where the actual file is being stored?

Thanks!
