cloud service providers

They are companies that provide cloud computing services and applications of various kinds, and each of the cloud service providers has its own data center so that cloud services are hosted in it, and those who use cloud services can access data centers through an Internet connection, so cloud services seem to be in a virtual place On the cloud.

Why go to cloud services?

Cloud services are a great benefit to users, whether they are individuals or companies, as cloud providers own large-sized spaces with high efficiency, and therefore instead of any client building the computer infrastructure to run his business through it, he goes to one of the cloud service providers and buys one of its services. This suits his needs, and he can have a shared computer infrastructure with many other clients, but each client works separately and isolated from the infrastructure of others.

Types of cloud service providers

Cloud computing is classified according to the service provided to:

Infrastructure as a service (IaaS): The infrastructure components are presented to the customer in the data center of the cloud service provider so that they can be accessed over the Internet without the need to purchase the client’s servers.
The basic system as a service (PaaS): The infrastructure components of the customer are presented in the data center of the cloud service provider so that they can be accessed over the Internet without the need to purchase client-specific servers. It also provides a working environment system that allows customers to access and use them in their business.
Software as a service (SaaS): Providing software applications and programs as a service. Instead of installing software on their devices, they can benefit from these reliable, safe, and specialized programs via the cloud.

According to these types, the types of cloud service providers vary, there are those who provide one type of them, there are those who provide two types, and there are those who offer all three types, and each of them has their own advantages that make them compete to provide the best cloud services to customers.

Cloud computing is classified according to how it spreads to:

A public cloud: It allows customers to access some services without the need to purchase them. It is available to everyone, such as Google documents available to everyone, which is an example of SaaS, the service as software and is free of charge
A private cloud: It is offered to a special class of clients based on characteristics that they specify, and for a fee
Hybrid cloud: It combines public and private clouds. There are those who use cloud services available to the public and may need some special services in their work, so they buy services from the private cloud for a fee.
A community cloud: It is provided by some cloud service providers to distinguish themselves from competing companies. This cloud is specialized in a specific sector, for example, the health sector, so that anyone in the health sector can benefit from health cloud services that allow health care providers to store information Patients and keeping backup copies of them, allowing any health care provider to view them when reviewing the patient so that he knows his full medical history to facilitate his work.

Thus cloud providers vary according to the type of cloud that they offer.
