Cloud storage is a method of data storage and organization that takes place in the cloud, a network of remote servers that can be accessed over an Internet connection. With cloud-based storage, users and businesses can store, access, and maintain their data from any location that offers an Internet connection, rather than confining their files to a single location or device.
Before cloud computing was common, users maintained their data on a personal hard drive or on-premise data center, limiting their use of that data to one location. Think of it like choosing to invest in a landline rather than a mobile phone. As long as the user is inside their house, they’re able to get to the phone whenever it rings, but as soon as they leave their property, they become unreachable. With a mobile phone, however, they can answer a call from any location.
It works the same way with cloud storage. Users no longer have to stay home (or inside their office building) in order to access their data 24/7; instead, they can take their files on the go without lugging around expensive and limited hardware.
