What is the best way to organize a semblance of a local network with a connected disk but via the Internet?

Question

Data synchronization

Video post-production. Large volumes of files for each project - from hundreds of gigabytes to terabytes.
The task is to unite the n-th number of freelancers so that they quickly get involved in the project, and do not have to download everything and synchronize. For example, you connected vpn and you have a virtual disk, as if in a local network.
Now it's a Google drive and it's inconvenient, constant failures.
How is it better to organize this so that there is a good speed, it is convenient to connect and disconnect users, distribution of rights is possible and inexpensive to use.
Maybe AWS-based solutions?
Yes, as a rule, freelancers are from Moscow, so maybe something native?

Answer 1

Terabyte synchronization between all freelancers? Is it really necessary for all users?
I'm ndex.Disk - is native enough?
Might be worth another look at Syncthing

Sync thing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

Answer 2

FTP is specially designed for such tasks.
