The University of Illinois provides a variety of cloud options for students and faculty to safely store their files in the cloud. Which you choose to use is completely up to you. You can choose one, several or all to store your files in the cloud, and each service has different benefits associated with it. 

Box offers 10GB of free storage space, and includes GoogleDocs integration for ease of file sharing. The software is ideal for business and has built-in encryption to protect your files.

GoogleApps and Office365 both offer 15GB of free storage space, and provide ease of collaboration through allowing multiple users to write on one document. 

Each of these options is easy to integrate with Windows, iOS, Mac and Android, and all are provided to you by U of I!
