The Cloud, also known as cloud computing, is a term that refers to services and applications that run on the Internet instead of physically running locally. Instead of storing information and data locally, it is stored on remote servers accessible from anywhere via the internet.
VoIP central applications in the Cloud, for example, refer to the use of communication services, such as telephone calls, videoconferences, instant messaging and other types of communication, which are carried out over the Internet using remote servers instead of using physical infrastructures.
