Office 365 is designed to enable its users to share, collaborate, and communicate in the cloud. Office 365 takes the Microsoft Office applications and combines them with hosted versions of Microsoft Exchange, SharePoint, and Lync (Microsoft's robust business communication tool). Office 365 is a reliable alternative to desktop applications, now with cloud storage, that will ensure that your information will be safe. Microsoft guarantees that Office 365 servers will have 99.9 percent uptime to make sure that your work will always be accessible.
Google Drive brings all the benefits of cloud computing to your small business. By having Google host your files securely in the cloud, your work will always be saved and backed up. You can also share your work with the specific people on your team that you give permission to, while blocking access from everybody else.
