Am I choosing cloud storage for a group of 100+ people?

Question

Data storage

Good afternoon - I ask for your experience in such a task - I need cloud storage for a workgroup under 100 +.
Here are my criteria:
1 I don't want to upgrade my hardware or virtual machine (do not offer owncloud).
2 I do not want to store data on users' PCs (there is a lot of data, users are unreasonable - throwing a Time Machine image into s3 is a common thing).
3 Differentiation of rights on directories ( R\OR\W ) - best of all within one array, creating several arrays for different groups is wrong in this situation.
4 Money is willing to pay. At the moment there are several iron nas around the world - they are old and there are many problems with them.
I spent a little time looking for alternatives and came to the conclusion that my choice is s3 or google cloud storage if mounted on end PCs and macs. There is such a Tnt drive tool - maybe everything you need for ~ 25. That's actually all - if you had a similar situation - then tell me, please, your choice.
Thanks in advance.

Yes, everything can be adjusted. In IAM, it will be possible to set up users and give everyone access only where they need to. I would advise creating a bouquet for each user. It will be more convenient to monitor and configure. If you give each bouquet a tag, then it will be possible to look at billing by users. Who screwed up how much.
And I fully support the choice of S3. This is a super stable, fast and reliable system. They have a slightly cheaper S3 called Redundancy Storage. There they provide 99.99% file safety. This means that 1 file out of 10,000 may be lost. Well, the standard storage is 100%. Unless, of course, a global catastrophe.
Plus, a lot of software is written on S3. If not the utility that you mentioned, then another. Something is still there to work with files.
