Cloud – What is the difference between Public / Hybrid / Private Cloud?

Cloud refers to the environment or “marketplace” in which cloud computing resources and services are offered. Probably the three best-known providers of a public cloud are Google (GCP), Amazon (AWS) and Microsoft (Azure).

But what exactly does public cloud mean here?

Well, we differentiate between various “delivery models” for cloud computing, which I would like to explain in a little more detail below.

1. Public cloud

Probably the best-known cloud model is the public cloud, where the resources and services offered are generally available and thus shared between all possible users and customers. Enormous cost savings can be achieved here.

2. Private cloud

Here the resources and services offered are provided specifically for one customer and are therefore exclusive. Within a company, this could be provided by an internal department as well as an external third-party provider. This usually offers the greatest possible security and may be mandatory for some applications for “compliance” reasons, but is probably also the most expensive cloud variant.

3. Hybrid cloud

This refers to a combination of public and private cloud. Here, general and non-critical services could be reserved in the public cloud for better cost savings and a private cloud could be used for the more critical services.

4. Community cloud

A type of private cloud, but released for a specific range of users, is called a community cloud. This could be, for example, a cloud environment for an association of universities, or several companies that have joined forces and use a common cloud environment.

5. Virtual private cloud

An area reserved exclusively for one customer on the public cloud is usually referred to as a virtual private cloud. Here, IT precautions must be taken to ensure that no cross-client access to the reserved resources can take place.

6. Multi cloud

This could be described as the next evolutionary stage of the hybrid cloud. Here, several of the cloud models mentioned above are integrated into one system architecture. This offers the greatest possible flexibility, but also an additional organisational and financial outlay that should not be underestimated.

Checklists are generally used in the selection process to map the respective requirements to one of the models.

Of course, we are here to help you find the right cloud provider for your personal I/O.nite experience.
