In the hybrid cloud, a private cloud and a public cloud are combined into one entity. The public cloud is what people usually mean when they referring to the cloud. On large server clusters a user (or an entire business) receives a specific area, but not a self-contained physical server. This means that in a public cloud, two companies can use the same storage module and share its space.
In a private cloud, in contrast, other users have no access to the hardware. Private clouds can be booked with external providers as well. The servers in this case are not on a company’s premises, but in a remote server cluster. In this way, the user enjoys advantages that are also provided by public clouds, but with more data security. An on-site datacenter that a company operates itself can also be set up as a private cloud. For this purpose, the server can be configured in such a way that it can also be used by employees who are located at a different location.
The Hybrid Cloud is a combination of both solutions. With this model, a company uses the private cloud for specific work aspects and outsources everything else to a public cloud.
