Depends on the domain. There's a bunch of sciences using large datasets served up efficiently using static file formats, e.g., https://zarr.dev/ and https://parquet.apache.org/
Admit I'm not familiar with that domain. But don't people use managed services even there? In my job we host parquet files on S3.
