What is Cloud Computing? Definition of Cloud Computing & Examples

The word “cloud” means “cloud.” It refers to a number of remote online storage systems in computer science. In other words, it’s a device that can store your information only through the Internet on distant computers (known as servers). This is the latest data storage phenomenon. The cloud is also known as cloud computing, meaning that you can still use the words associated with the naked era of computers, cloud computing.

Cloud computing is generally just a general concept that refers to the provision over the Internet of hardware and software. The degree to which the services are to be rendered is not specified. This ranges from a simple Cloud Storage, where users can store on remote servers, to a cloud network, where companies have complete data centers, as well as their own hard drive space on the Web.

Definition of Cloud Computing

Cloud computing remains generally a set of solutions that enable various services to be delivered on-demand through the Internet. All your data is saved on a remote server rather than on the hard drive of your computer by this system. Today, both businesses and individuals use it.

There are therefore different forms of cloud computing and it is not always easy to pick a cloud according to your needs. Why is cloud functioning? Why does such a storage device have advantages and disadvantages? Which are the various cloud computing types? Both of these questions need to be addressed adequately. Figure out here about the cloud you need to know.

Class Computation the Job Principle

The cloud continues to be a computing network. This is a series of servers that store client data and the connection (cables or fiber optics) through which customers access this. It continues to be owned by a company that offers cloud services to clients of various geographical locations. This remote server is a big and secure machine that operates with powerful operating systems (several processors and a lot of RAM) and frequently updated applications and software.

It is rarely attacked by a computer virus. It provides different services to all customers who connect to it over the Internet or through private networks. The service provider provides an automation system in its software that allows the customer to control the server and the network accordingly. Therefore, consumers of this service shall not comply with a cloud guideline. You remain autonomous and work as if the data were saved on your own hard drive. The user of the cloud does not know the geographical location of the data centers.

Cloud Computing Different Types

There are various types of clouds on the market that meet your unique needs. You have a wide range of clouds, whether it is to simplify activities or to handle the operations more conveniently. Here are some! Here are the others!

The Public Cloud

It is an application that allows you to save your data on servers online, which are also available to other users. There are a small number of users. Public cloud pricing varies according to the amount of data that you store on the server. You are paying as much as you store or collect details. This form of cloud provides virtually unlimited data for its users.

The Private Cloud

It remains the property of an individual, as the name suggests. A cloud is typically ideal for businesses that want complete control of their personal data, apps, and applications. Such servers may be located in places that do not belong to the client. Nevertheless, a third-party service provider can also handle the servers. The customer has direct access to this sort of cloud. The creation of this server requires significant financial and logistical resources. The user has complete control over this powerful and stable cloud.

The Cloud Hybrid

Many companies started to use this cloud form. In reality, a combination of the public and private cloud is the hybrid cloud. This remains the prerogative of large companies voicing individual needs. They currently have two kinds of data (confidential and non-confidential data) in the control of their various operations. Within the private cloud, confidential data is stored, and other information is kept in the public cloud where everyone can access it.

An example to understand about Cloud Computing

Let’s take a simple example, compare computing with video.

Before to watch a movie, you needed:

the DVD of the film, (or the VHS cassette for the older ones)

the DVD player.

A television.

Now, with VOD (Video on demand), all you need is:

a television connected to the Internet.

We can compare the cloud to VOD (Video on demand).
If you rent a movie on demand with your TV connected to the internet:

– no need to have a DVD or blue-ray player at home, that’s what is important: being able to watch the film.

In fact, we are going to use a service that replaces the hardware: this service is called VOD.
(For your information, the films available for VOD are stored on servers which are in the Cloud).

Now let’s make the same comparison with cloud computing, and you will see that the cloud: it’s services.

Without cloud

Before, to store and view your digital photos, you had to:

a computer,

and a sufficiently large hard drive.

Disadvantages:

if your computer crashes: you can no longer see them

if your hard drive fails: you lose your photos

your hard drive must have enough capacity to store everything, because if you run out of space, you will have to buy a new hard drive or a new computer.

you can ONLY view your photos on your computer (unless you have shared the folders containing the photos).

With the cloud

With the cloud: we will use a storage service

a device connected to the Internet. (tablet, computer, television, smartphone, etc.) is sufficient to view your photos.

Benefits :

Photos are not stored in your home, they are on computers that are secure and backed up – you cannot lose them.

you rent the necessary disk space. When you run out of it, you rent bigger.

you do not risk losing your photos because of a hardware problem (hard drive failure), it is the host who manages the equipment.

you can access it from anywhere and with any device: concept of ATAWAD. (see on part 2).

Example of online services

For individuals, the cloud comes down to online services among them one of the most used is document storage (also allowing sharing) such as: Hubic, DropBox, Google Drive, …

… But you can also find software for document creation, image processing, drawing management and many more…

here are for example online office tools:
