I asked for advice on how to express something in UML once:

“No one cares whether you follow the UML standard, just make something up”

“But my company uses waterfall and requires UML diagrams to move onto the next phase of development!”

“That’s an issue with your company then. Ask your boss how to do it. Question closed.”

I was considering this. The hosting provider we use for model training runs doesn’t charge for ingress/egress. Their storage costs would eat us alive though haha. OVH looks much more promising.
