Public Cloud, Private Cloud, or Hybrid… What are the differences between private and public cloud cloud and what is the most suitable choice for your business to store data thanks to Cloud Computing?
In order to make the right choice, there are several key criteria to compare to distinguish the advantages and defects of these different solutions.
The public cloud
THE Cloud Public is managed by an external service provider, which hosts the company data using its own infrastructure.
The private cloud
THE Cloud Private consists in storing internal data and information on the company's own servers.
Now that the terms are well defined, let's examine the main points of difference between these two cloud computing solutions.
Differences between private and public cloud cloud
1) Price difference between private and public
The first difference between private and public cloud is obviously the price.
The price is of course an important factor in the choices of a cloud service. And, in general, the private cloud is more expensive to set up and maintain than the public cloud.
Indeed, it requires having a substantial internal infrastructure (servers, data centers), which is not within everyone's reach.
It becomes much more interesting for companies already with good -sized technical resources.
On the other hand, the price of the private cloud tends to be quite stable, where public cloud rates evolve according to needs.
2) Security between public and private cloud
The second difference between the Public Cloud and the Private Cloud concerns the security of the data transit in it.
Data security is of course a major concern for any organization. All the more with current restrictions on the GDPR for example.
Companies storing a large number of sensitive information will certainly prefer to turn to the private cloud: being entirely dedicated to the company, its access is much more limited and protected.
What is more, with a private cloud, very few resources (or even any) are shared with other organizations, thus limiting risks.
The public cloud, although it is completely reliable, inevitably presents more weaknesses at this level.

3) The difference in flexibility between private and public cloud
A company continues to evolve over time, and its cloud needs also. The flexibility of infrastructure is therefore the third difference between private and public cloud.
While your resources grow, the amount of data to be accommodated can be increased tenfold, and it is important that your cloud service follows the pace.
In this situation, the public nailed show higher flexibility, since the service provider can quickly increase your storage or data download capacity (for finance, however).
With a private cloud, an increase in needs can be problematic: if your infrastructure does not allow more information to be accommodated, needs: Public Cloud evolves more easily
4) Personalization of your cloud solution
The fourth difference between the private cloud and the public cloud is its ability to be personalized for your organization.
And in terms of personalization, it is most certainly the private cloud that emerges victorious.
More controllable and controllable, it allows you to be as close as possible to the needs of the company in terms of accommodation and management of its data, but also of the performance of the equipment and the network.
The public cloud is dependent on its supplier and therefore less adaptable.
5) The difference in speed between private and public cloud
The last difference between private and public cloud is the speed of implementation and operation.
An undeniable advantage of the public cloud is that it can be implemented fairly quickly, being completely outsourced.
The installation of a private cloud is longer and laborious, especially if the company does not have sufficient infrastructure upstream.
An alternative to private or public cloud: hybrid cloud
THE hybrid cloud is, as its name suggests, halfway between private cloud and public cloud.
With a hybrid cloud, an organization can for example manage its internal data (private cloud) and have recourse to a public cloud service if necessary, in particular in the event of a momentary increase in its needs.
We can also mention the virtual private cloud : it is roughly a public cloud whose security is reinforced and the bandwidth more efficient.
