You might know of "the cloud"—that nebulous technology term that refers to a place where stored files are accessible from virtually anywhere—in terms of where you keep your music, photos, and other media to avoid filling up your phone's internal memory. And that's right—but the cloud is much, much bigger than that. Businesses around the globe also rely on the cloud. That became immediately apparent on February 28, 2017, when Amazon Simple Storage Service, A.K.A. Amazon S3, went down, causing service outages on a ton of different websites including Netflix, Airbnb, Twitter, and Slack. Amazon S3 provides web hosting, file storage, and backup services for more than 1 million clients, making it one very big example of a cloud service. Learn more about the technology behind "the cloud" in the videos below.
