The cloud is a kind of infrastructure or hardware servers that make up a data center located at strategic points, in which information that travels over the internet is stored. Clouds must meet certain safety standards to be certified as safe. For example: they must have at least two power sources, they must have moisture-free spaces within the facilities, they must be at a certain level from the floor, among others. There are several cloud providers such as Amazon (Aws), Microsoft (Azure) or Google.
