Many companies prefer to use other forms of server instead of on-site servers, the most popular of which is remote. Indeed, cloud computing is a system that allows companies to save a lot of money on hardware, and makes their data more easily accessible. What are the different models and what do they do? Read this article to learn more about the cloud.
Definition of PaaS
The cloud operates mainly through three types of public cloud servers, including PaaS. This leads to the question: what is paas? To this question, it is possible to answer that PaaS is a solution, a cloud computing service that allows the user to access a programming platform via several means. Whether it is :
- An interface that is connected ;
- A control panel;
- An API;
- Etc.
Thus, this hosting company takes care of all the tasks related to software maintenance and your IT infrastructure. To use Platform as a Service (PaaS), all you have to do is pay a subscription to your cloud provider. Since this platform works on the basis of a public cloud mechanism, it is up to the user to select either the software or the application he needs. And he pays for that licence. As a result, your company can benefit from the advantages of various servers without spending money on IT infrastructure and maintenance.
How the various types of cloud computing work and the differences between them
Cloud computing is made up of different service models that are subscription-based. Each has its own way of working and its own advantages in terms of a cloud computing solution. Thus, there are some notable differences between them.
Indeed, IaaS is a service that allows users to have external infrastructures at their fingertips in exchange for a subscription. These are used for data storage. With this service, the hardware is the responsibility of the service provider and the user is only responsible for the operating system and the data.
PaaS, on the other hand, offers the same advantages and services as above. The difference is that it also supplements the accompanying hardware. Especially when it comes to computer applications and data.
The SaaS formula remains the most popular among the cloud computing models. It is used both by the public and by private companies. In order to benefit from its services, the customer must pay a monthly subscription fee. This gives the customer the opportunity to make use of the platform of the service provider, who is responsible for the installation and configuration of the maintenance equipment.
What is cloud computing?
Cloud computing is a whole system of distributing IT services remotely. It does this by hosting them in an external data centre instead of a dedicated server.
For its operation, it is available in three main types. These are the public cloud, the private cloud and the hybrid cloud. Generally speaking, the public cloud is a cloud deployment that is made available to several companies or users. This means that this cloud is not exclusively the preserve of a single company.
In the case of the private cloud, it is intended for and used by a single company or organisation. As for hybrid or shared cloud computing, it is the combination of public and private clouds.
In short, cloud computing is a medium whose operation depends on certain service models and three types. It offers various advantages to its users on various levels.
