What’s Cloud Computing? How does cloud computing work?

A cloud can be private or public. A public cloud sells services to anyone on the internet. A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people, with certain access and permissions settings. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services.

How does cloud computing work?

Cloud computing works by allowing client devices to access data over the internet, from remote servers, databases and computers.

An internet network connection links the front end (includes the accessing client device, browser, network and cloud software applications) with the back end, which consists of databases, servers and computers). The back end functions as a repository, storing data that is accessed by the front end.

Communications between the front and back ends are managed by a central server. The central server relies on protocols to facilitate the exchange of data. The central server uses both software and middleware to manage connectivity between different client devices and cloud servers. Typically, there will be a dedicated server for each individual application.
