Good tutorial in French explaining the features and benefits of Hetzner's Storage Share service, a cloud storage solution that integrates with Nextcloud, a popular open-source file management platform.
From just €4.29 per month, you can get your own Nextcloud instance as an alternative to Google, Microsoft, etc. It comes with 1 TB of storage, unlimited users and is hosted in Europe.
It's not free, but neither are the US competitors — it's actually cheaper than Google One (10€) or Microsoft 365 (13€).
You don't need any IT skills to install it; just create an account, pay and start using it. 
You can do it only for yourself or offer storage to family, friends and your community too.
