SkyDrive cloud storage is now open for access to third-party applications. Microsoft team has released an update to SkyDrive for both Windows and Mac, as well as for iOS and Windows Phone. With the update, we can write applications that are able to access files in the cloud directly from their PC/Mac or mobile app. With the SkyDrive API, we can utilize SkyDrive to build an app on any platform.

If we are developing social or collaboration applications that utilize cloud storage, SkyDrive is option worth evaluating. Apart from Google Drive API and Amazon S3 storage alternatives, with SkyDrive API we can utilize the SkyDrive API to build mobile and tablet apps that provide directly access to a user's documents and photos, which are stored on SkyDrive. As SkyDrive provides iOS, Android and Windows support, we can build mobile applications on multiple platforms by leveraging this API.
