3 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

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.

Private Cloud

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

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.

Hybrid Cloud

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.
