Cloud apps have become popular among people who share content on the Internet. LinebreakS.L., based in Spain, offers a cloud app named (appropriately enough) "CloudApp," which allows subscribers to share files, images, links, music, and videos. Amazon Web Services offers an "AppStore" that facilitates quick and easy deployment of programs and applications stored in the cloud. Google offers a solution called "AppEngine" that allows users to develop and run their own applications on Google's infrastructure. Google also offers a popular calendar (scheduling) cloud app.
