What is private cloud and public cloud?

The public cloud provides IT services publicly over the Internet. This is done via groups of interconnected servers, known as server farms. These services, such as the Microsoft Office 365 products, can be used by anyone. The public cloud means that companies don’t have to deal with the administration of IT as this is handled by the providers. A private cloud offers companies greater control and security. Here, too, the services are made available via the Internet or an internal network, but only for a clearly defined group of users. Users of a private cloud benefit from the advantages of cloud computing (including scalability, performance, no acquisition costs), but at the same time also from the specific control and customisation options of the private cloud.
