Ask HN: Are there any realistic corporate cloud data storage solutions?

Hello Hacker New, I've been on a quest to find a corporate cloud data storage platform for over a year now, and have yet to come up with anything that fully meets an enterprises needs. Here is a list of what a true solution needs, anyone know of a company that I do not?

Centralized File Storage not tied to any one user, but to the company account.

Admin controls over folder permissions, regardless of who uploaded the folder/files

Individual file vesioning. Most providers have this.

Folder level versioning to allow an entire folder to get rolled back to a previous version, instead of each file individually.

Functional LAN syncing between clients on a local network in order to avoid massive bandwidth usage on active accounts.

File Locking! This seems to be the Achilles heel to cloud storage? I can't believe a company would roll out a product as enterprise ready without file locking. We use to have a cloud storage provider who had file locking, and it worked great for us, however they took the feature out because it caused problems for other clients.

No Maximum file limit, Size limits are ok if we have the ability to purchase additional storage, but onedrive for business has a 20000 item limit per site, and a 5000 limit per subsite. Meaning nearly every one of my clients cannot use onedrive for business.

Please HN, help me find something that works!
