In general, cloud computing means, you keep all the data of your computer or laptop on the Internet instead of storing it in the hard Drive of that computer, it is called cloud computing. When you keep your data stored on the hard disk of the computer, then you can access it only from that computer. But if you store that data in the cloud i.e. on the Internet, then you can access it from anywhere and from any computer.
Due to the feature of cloud computing, it is popular nowadays and everyone has started using it too. It is possible that you are also using any cloud application. If seen, the need for cloud computing is increasing nowadays. Not always everyone is taking their system, but they save their important data in the cloud and access it from anywhere.
Nowadays, along with cloud computing, the desire for distributed computing has also changed. So let’s know without delay what is a cloud computing and the types of cloud computing are there.
What is cloud computing?
It is the technology by which a user can store their data on the Internet or access software or services online. In simple language, if you do not keep your data on the hard disk of the computer and store it in the cloud storage of the Internet and access it, then it is called cloud computing.
When a user keeps his data or software in the local drive i.e. the hard disk of the computer, then he has to depend on that computer. But if that user keeps his data in the cloud that is in the internet platform, then he can extract that data from any laptop, computer, or mobile too. It is a pleasure that you can access your data anywhere. You won’t need to carry a particular computer everywhere.
Nowadays there are many services available on the internet. Many facilities are available such as cloud storage, online video, website, and software service.
In this, the service that the user needs, he uses it by paying for it. For this, the user does not have to create any platform or infrastructure. Nowadays the user needs service all the time on the internet.
As an example, all the users nowadays using YouTube, Facebook, WhatsApp, Instagram, Twitter, Google Drive, Google Photos, etc. In which you upload photos, upload videos, and also access it. All these cloud software has become a necessity for people. That’s why the importance of cloud computing is very high in today’s time.
Importance of cloud computing
It costs a lot of money to establish a small or big IT company. It is necessary to have a server room in a small or big IT company. In which database management, firewall, mail server, and the entire network are operated. Many devices are required to perform this task. Such as router, modem, switch, and hub. Engineers are appointed to operate all these.
To solve this type of problem and reduce the cost of infrastructure, nowadays all the companies have started using cloud computing. In this, the company has to buy storage in the cloud. And uses it according to its use, which costs less than all those components.
In cloud computing, it reduces the demand for hardware and software from the user. In this, the user should be able to operate. It is as easy as operating a web browser. All of you do some popular cloud computing web service every day. For example Gmail, Yahoo, Hotmail, etc.
When you use all these mail cloud services, it does not ask the local drive to keep the data in it. It stores in its cloud storage and you can use it as per your requirement.

The types of cloud computing
Services model of cloud computing
Generally, there are 3 types of cloud computing services models.
- IaaS (Infrastructure as a Service)
- PaaS (Platform as a Service)
- SaaS (Software as a Service)
The full form of IaaS is infrastructure as a service of a cloud computing model. In this type of service model, cloud computing power, network power, storage, software, and all other controls are operated by users. This type of service model is used mostly for businesses purpose.
Some cloud providers offer this service to businesses as a virtualized infrastructure. In this, businesses outsource storage, server, and cloud networking with the help of the internet.
This service model is very useful for those who are small businesses and do not want to spend money on infrastructure. There are many hardware devices, network devices, external storage devices, and a lot of expenses to maintain in a year. But by using the IaaS service, this cost will stop and money will be saved. An example of this is VPS (Virtual Private Server), in which you also get network, software, and computing power.
The full form of PaaS model is Platform as a Service. This service model is for users who work on software design, application development, and service. This service provides the convenience of working in the cloud via the Internet.
You know that there are many software development and design tools on the Internet, with the help of which developer applications get serviced. All this work is being done due to PaaS service model.
This PaaS service keeps updating its service from time to time and keeps adding new features. Which is beneficial for software developers, web developers, and businesses. This includes software support services, management services, storage facilities, networking, deployment, testing, collaboration, hosting, and maintaining applications.
The full form of SaaS is Software as a Service. It is third-party software that is provided by the vendor or service provider to the customer to access it through the internet.
This software is designed according to the user so that the user can use it from any place in the world. This type of software has to be purchased from the vendor. Through this software, HR management, accounting, invoicing, etc. work can be done.
Types of cloud computing based on Deployment
Based on deployment cloud computing is also divided into 4 types.
Public Cloud is available to everyone and it is managed by the service provider only. These services are often free or charge very little. For example, Amazon Web Services (AWS) and Microsoft Azure, all of them are Public Cloud Computing.
In a Private Cloud, services and networks are stored on a single private cloud (server). In this, the user uses this private cloud for himself. This cloud storage can be used by only one user and no other person can access this cloud storage. For example, Google Drive, and Dropbox are private cloud computing. All your data in these drives are secured with your own user id and password and you can access this cloud storage only with the help of your user id and password.
Community Cloud is made for only one group of people. Apart from that group, no one else can access the data that is in the cloud. For example, in a government office, only its employees will be able to access all the data kept on its site. It also keeps user ID and password protected.
A hybrid cloud is a combination of both private cloud and public cloud. Also, you can use the cloud according to your need. That is, you keep the important application in a private cloud and you keep the rest of the application in the public cloud. Some things on a site are available only to the registered people and some things are available to the public. Such a cloud is called Hybrid Cloud.
History of Cloud Computing
Cloud computing is believed to have originated in the 1960s. Then the internet was not even started properly. The real beginning of cloud computing took place 30 to 40 years later in 1990, when a company named Salesforce started providing services to its website people. Only then did it become known about how importance of cloud computing is and how this feature can be of great use.
After many years, this field gained momentum and as soon as the 22nd century came, many big companies like Amazon, Google, Dropbox, and Microsoft started providing their services in the field of Cloud Computing.
Advantages of cloud computing
