What is Cloud Computing? Advantages Of Cloud Computing

Cloud Computing is the service in which the on-demand computing resources are provided to the user as per their requirements. The services like storage, physical and virtual servers, virtual machines, database,s etc are provided. All these work on a pay-as-you-go basis.

Cloud Computing is very helpful for small businesses as they can't afford to establish their own computing resources and also maintenance is costly.

Types Of Cloud Computing

There are different types of Cloud computing services that are being provided in the market.

1. Software-as-a-service ( SaaS ) 

In SaaS, the software applications are provided to the users. The access is given via a web portal or a dedicated API. The software applications are hosted on the cloud.

2. Platform-as-a-service ( PaaS )

In PaaS the hardware and software applications are provided, the computing resources with development tools are given. The more advanced use of cloud computing is provided here. PaaS also works on Pay-as-you-go Basis.

In PaaS services, cloud provider gives everything from servers, storage, computing applications, database, etc. The users have just to have access to it

3. Infrastructure-as-a-service ( IaaS )

IaaS is the Higher version of PaaS. Here you are provided with all the computing services, from physical and virtual servers to databases. Operating systems, storage, development tools, etc and many more are there to use. It works on a Pay-as-you-go model. Mainly companies with large technical ecosystems work on IaaS.

Advantages Of Cloud Computing


Cloud Computing saves the cost of establishing infrastructure and maintaining the data center. Also, the users have to pay only for the resources that they use.


Cloud Servers work way faster than normal servers. Cloud resources process the applications very fast. Huge files, data, resources are processed in seconds and minutes. Its saves a lot of time and money. Also with the cloud, you can go wide in regions. You get multiple regions allowed you can deploy your applications in any region in minutes.


Establishing your own data center requires a lot of racks and stacks. You need hardware and software setups and also maintenance costs are also applied. But in Cloud Computing you get access to all the development tools, applications, operating systems in one place without any issue.


In the cloud, the data and applications are hosted in a wide manner. The things work on multiple servers and also have a strong security layer. Bypassing cloud computing security is not so easy and it makes your data safer. Big businesses always save their backups on multiple Clouds.

Types of Cloud

There are different types of Clouds provided by the service providers in the market. Mainly there are three clouds that are provided by the sellers.

1. Public Cloud

In Public Clouds, the service provider manages the whole infrastructure and provides the computing resources to the consumers on a pay-as-you-go basis. In this case, the Cloud has all features which should be there but it is provided to multiple consumers. The consumers have access to the resources and services via a web portal. You can operate and manage it easily.

2. Private Cloud

The Private Cloud is like a whole computing infrastructure is used by only a single Organization. It can be built up at the user's own location or also can be sourced by the provider's data center. The Private Cloud provides the best Security and is also the fastest in terms of processing.

3. Hybrid Cloud 

A hybrid cloud is a combination of private and public clouds. It is for the people who are cost-saving and quality at the same time. In a hybrid Cloud some of the resources are hosted on public Cloud and some of the resources are processed on a private Cloud. Both are interlinked and it gives additional support.
