The public cloud
A Cloud Public is a accommodation dedicated to different customers, who share the computer resources of the same infrastructure.
In most cases, organizational data is stored on a remote server, which does not belong to the company. Nevertheless, some Public cloud suppliers offer their services in their customers’ data centers.
Even if the infrastructure of a public cloud is shared, user data is stored there separately. Concretely, the company has a dedicated storage space to which other customers do not have access.
The advantages of the public cloud
Accessibility
The public cloud is appreciated for its ease of use. Indeed, There is no physical infrastructure to deploy To be able to use it, since it is instantly accessible using a simple internet connection. In addition, the public cloud supplier takes care of equipment maintenance and updates.
Flexibility
In terms of infrastructure, Public cloud services give access to an almost unlimited capacity. It is therefore possible to store a large amount of data and run many applications. In the event of a rise in charge, the shared cloud adapts to the evolution of the company’s resources.
The cost
With the public cloud, payment is made for consumption. The company only pays what it useswith the possibility of renting software rather than acquiring licenses. In addition, it does not need to provide a budget dedicated to the maintenance of the infrastructure.
The limits of the public cloud
Public clouds depend on the Internet to provide services, which can cause performance and availability problems. In addition, they do not offer the same security guarantees as the private cloud.
The private cloud
Unlike the public cloud, the Cloud Private is dedicated to a single customer: the infrastructure is therefore not shared between different users. This type of cloud solution can be hosted on the company’s servers or externally in a data center.
Indeed, there are two administration options:
- THE Internal private cloud is managed and maintained by the organization.
- THE Private Cloud Hosted is administered by an external cloud service provider.
This architecture is ideal for companies wishing to have a complete mastery of their cloud environment.
Private cloud benefits
Control
Generally, private cloud users own their infrastructure and the software they use. So they have total control over their cloud and its configuration. In addition, they benefit from better control of its performance, while power reductions can occur on a public cloud, especially in the event of a peak activity.
Security
The private cloud offers high guarantees in terms of sensitive data protection and confidentiality. First of all, because access is shared with a limited number of users. But also because this type of cloud infrastructure can be isolated from the Internet, which limits the risks of computer attack or data leakage. In comparison, public clouds do not offer such a level of protection, although they meet safety and compliance requirements.
Personalization
The private cloud allows the company to personalize its cloud environment from A to Z with, for example, specific storage and tailor -made features.
Private cloud limits
Despite its assets, the private cloud requires higher investment expenditure. It is also less flexible than the public cloud, which easily gives access to a wide variety of services.
The hybrid cloud
THE hybrid cloud is an environment made up of several interconnected clouds. As its name suggests, it combines the public cloud and the private cloud, everyone can be used where it is the most suitable.
This mixed architecture also makes it possible to associate a on -site infrastructure with a external cloud environment.
The advantages of the hybrid cloud
Versatility
The hybrid cloud is distinguished by its agility, because it allows juggling up different types of cloud according to needs. In addition, it can adapt quickly to workload variations, as well as to projects requiring great computing power.
Security
The hybrid cloud architecture solves certain public cloud safety problems, as it offers better control over the accommodation of workloads and how they are protected. Concretely, The most sensitive data can be stored on a private cloudfor maximum security. As for less confidential information, They can be easily and lower at lower cost on a public cloud.
The simplicity
Thanks to the pooled public cloud resources, a hybrid cloud infrastructure is easier to administer and configure than a private cloud.
The limits of the hybrid cloud
If it brings together the “best of the two worlds”, the hybrid cloud also has certain drawbacks of the public cloud, such as the risk of confinement in a specific platform for a supplier, and the private cloud, such as the management of an internal accommodation infrastructure.
Private Cloud, Public Cloud, Hybrid Cloud… Each solution has its own advantages, but also its limits. Thus, the company must take into account its specificities, its needs and its budget to choose the most suitable infrastructure between public, private or hybrid cloud.
