There are a couple of different ways in which cloud services can be made available Let’s quickly go through the main cloud development models:
Public cloud, the most popular model, as the name itself suggests it’s publicly available to all users. The service provider maintains the servers, where data is created and stored. Public clouds are a great option for companies that don’t want to invest and be responsible for maintenance of their own hardware.
Private cloud is, contrary to public cloud, a model in which cloud computing resources are available only to the specific organisation to which the hardware is dedicated to. Private cloud is the choice for institutions where top-notch security is the number one priority – for example in banks or governmental organisations.
Hybrid cloud encompassess the traits of both private and public clouds. The use of a hybrid cloud depends solely on the organisation, but most commonly the more sensitive data is stored on the private cloud, while supporting applications are kept in the public cloud.
