At a glance
Cloud models describe how a cloud is provided and how access to it is regulated. There are three important cloud models: Public cloud, private cloud and hybrid cloud. In addition, there are some highly specialized variants, but they are rather rare.
A public cloud can be accessed via the Internet, e.g. as online storage space for photos and documents or for cloud-based software or hardware. As a rule, the services of a public cloud are available to anyone who wants to use them. Participants usually rent resources such as memory, computing power or infrastructure for a fee and thus do not have to provide the corresponding resources themselves. The technology is available for both private and business users.
A private cloud offers a higher level of security and control by not being accessible online. Instead, it is only available internally to authorized subscribers, such as a company or government agency. Private clouds can either be hosted in-house and available over the internal network, or they can be hosted by an external provider and accessible only via VPN. This type of cloud is also called corporate cloud because of its strictly limited access and practical benefits for companies.
The hybrid cloud combines private and public clouds to take advantage of both solutions. Within the hybrid solution, public and private clouds remain cleanly separated. Data exchange takes place via a secure interface. This hybrid solution makes it possible to offer a cloud solution from a single source and still handle critical applications and data with increased security.
Other cloud models
There are other variants of cloud models that extend the models described above for specific use cases:
Like the public cloud, users can access various cloud services via the Internet. However, there is one limitation: the community cloud is only available to selected participants. This cloud model is used, for example, when several organizations have similar requirements for a cloud system and want to share it. This is ideal for joint projects or for more efficient use of resources in general.
The term is often mistakenly used synonymously with the hybrid cloud. In fact, however, a multi-cloud is a combination of different clouds that are all the same type - so all clouds involved are either private or public. The clouds involved can come from different providers. For example, it is possible to combine an existing cloud with another to enable new features that the existing solution does not offer.
Virtual private cloud
Virtual private clouds are private clouds that are located within public clouds. By means of virtualization, the private area is securely shielded from the publicly accessible part.
Our cloud model: ROBIOTIC.RICO
ROBIOTIC.RICO is what we call our intelligent software architecture - our heart. This is where all information is processed quickly and securely for our customers. The sensor and machine data are collected centrally in the cloud (Amazon Web Services & Google), where they are available for further evaluation and visualization.
