“The cloud” is something of a buzzword these days: there’s lots of talk about it, but not everyone knows what it means. Windows Live SkyDrive [http://explore.live.com/skydrive] is a cloud-based document storage service, and what that means is that it can keep your documents safe from damage or getting lost, allow you to copy those documents to any computer at any time, and enable you to share documents via email or collaborative editing. The cloud component refers to where these documents are stored; rather than keeping them on your computer, they are in a password-protected portion of the Microsoft servers, completely isolated from the various threats that go along with everyday internet usage.
SkyDrive is integrated directly with the latest version of Microsoft Office (Office 2010). What this means for the user is that files typed up in Office programs, like Word and Excel, can be saved directly to SkyDrive [http://explore.live.com/skydrive-get-started?T1=t2], saving you the hassle of uploading them yourself. In addition, new Word, Excel, PowerPoint, and OneNote documents can be created directly within SkyDrive, and the use of Office Web Apps allows said documents to be edited directly. The Web Apps also allow for collaborative editing [http://explore.live.com/skydrive-share-photos-files?T1=t4], so multiple people can work simultaneously on the same document without the clutter of multiple copies or edit merging.
Another use for SkyDrive is photo sharing [http://explore.live.com/skydrive-get-started?T1=t4]. Whereas normally sending photos in an email would require attaching them individually, and thus being subject to attachment size limits and inbox clutter, SkyDrive can be used to store entire albums of photos and then simply linked to in the email. The recipient can then browse and download photos from the SkyDrive at their leisure. At the same time, permissions can be set on the SkyDrive so as to keep some documents private while others are available to anyone.
While SkyDrive is currently somewhat of a standalone product, it will be much more heavily integrated in Windows 8 [http://blogs.msdn.com/b/b8/archive/2012/02/20/connecting-your-apps_2c00_-files_2c00_-pcs-and-devices-to-the-cloud-with-skydrive-and-windows-8.aspx]. An app under the new Metro interface will allow SkyDrive files to be easily accessed and browsed outside of a browser, as well as making said files and the SkyDrive itself available from any other app. This is built-in alongside the open and save functions, so any app that can access files can access cloud storage through SkyDrive.
One of the greatest thing about Skydrive is the price – Skydrive is Free! 25GB of storage for your files for free! Skydrive apps are available for Windows Phone and iOS and there are currently a number of thrid part Android apps as well as the new OneNote for Android app just released from Microsoft that lets you access your notes on Skydrive from an Android phone.
