When talking about a cloud service we refer to services that are used over the Internet.
Before the cloud concept, everything about the processing and storage of data was done from your own computer. That is, we had to have the relevant programs installed on our laptop to make certain services funcionasen.
What we now allows cloud service is precisely the separation between programs before we were forced to install and run a particular tool. Effect is using management applications or systems remotely through the Internet, without having them installed.
Although we are not aware, every day we use a large number of services in the cloud: Google, Amazon, Apple, Yahoo, Gmail, Twitter, Facebook, youtube, etc.. to which we can access from any laptop or computer that has an Internet connection.
