Ten years ago, Yahoo and Google offered rapid creation of free file sharing and collaboration spaces — perfect for group papers, sports teams, families — in short, any group of people who needed to see a common, centralized set of files.
There's no shortage of Web hosted business-oriented file services in today's cloud era: OneDrive, OneDrive for Business, Box, Google, Dropbox, Salesforce Chatter, among others.
Most recently, Amazon announced its new enterprise cloud file sharing service, Zocalo. Zocalo will offer simple document feedback, centralized repositories, offline sync to laptops, phones and tablets, security and directory integration. As with many of these services, the costs are minimal to none, allowing users to stand up a new repository in minutes for a project with a credit card.
These services pose a real challenges for the Microsoft enterprise.
