Best way to share a Mosaic Dataset (raster imagery) externally

[ASw93]

I have a Mosaic Dataset that is made up of over 10,000 raster images.

I am wondering what the optimal method is for sharing this with someone external to the company. I know that a Mosaic Dataset has to be provided along with the actual raster images it is referencing and tiling together. So what would be the optimal way to store these 10,000 raster images, add them to a Mosaic Dataset, and then give it all to someone external?

Is the best method just to create 10,000 raster datasets within a GDB, and then the Mosaic Dataset within there too, and pass it all over as a GDB?

(I also understand that they will need to repair the mosaic dataset paths if copying to a different directory)

This seemed a lot more intuitive using Raster Catalogues in ArcMap.

One workflow I would recommend is sharing the mosaic dataset as a tiled map service using ArcGIS Pro.  One of the biggest advantages of doing this is not having to copy the 10,000 files out to someone external.  They use the tiled map service shared to them via ArcGIS Online or the Portal for ArcGIS (Enterprise).
