Cloud computing is an online data storage system that allows user to to save their data online. There are many cloud computing providers. This is a useful service that keeps the data safe and secure. Data saved here can not be lost and remains secured from any threat.
To understand how cloud works let’s assume that the cloud consists of layers, the back end layers and the front end layers. The front layers are the parts you see and interact with. For example, suppose that you access your Facebook profile, you are using software running on the front of the cloud whereas the back end consists of hardware and software architecture that allows you to see the data on the front end.
