What is cloud computing? (Definition).

In simple words, cloud computing allows small businesses and beginner companies to rents IT services instead of buying them for a lifetime. To buy or build own server for small companies and business is might not possible because it takes heavy investment. So, big companies who have their own servers, database, software, and hardware, provide you permission to use their computer power, and instead of it, you have to pay some rent to the cloud provider companies. However, the rent of cloud services is not fixed. It totally depends on how much you are using the database storage and servers. 

There is no limit to the use of databases, networking, servers, storage, software, business intelligence, and analytics in cloud services. Simply, cloud computing provides you the virtual infrastructure for your company or business. Rather you have not big servers which can handle lots of traffic and a database that can store lots of users’ data, you are using it. For this amazing and virtual technology, we all are thankful to all companies which provide the service of the cloud.

At last, the final definition of cloud computing is that cloud means internet, and computing means infrastructure. Cloud service is a virtual online service that connects your all computer to a secure network so that all can share data and work together.

Types of cloud

There are 3 major types of cloud services. Public cloud, private cloud, and hybrid cloud. Other 6 types of cloud also available such as community cloud, multi-cloud, distributed cloud, HPC cloud, Big data cloud, and last is poly cloud. 

Here, I have explained 3 major types of cloud services one by one.

Public cloud

Let’s understand the public cloud via example. Google Drive, Adobe cloud, Amazon AWS cloud, and one box, etc. are the popular public cloud service providers. Here, all things related to the system, hardware, storage, and database the third party company owns. You have to simply make an account there and start using it.  

While using the public cloud customers need not focus on handling the whole cloud system. Customers can use it only by making an account. All the above service providers give some free space in the cloud which you already know. If you need more storage then you have to pay charges. That is the thing about renting the service and you pay according to how much you are using.

Private cloud

From the word private you can understand that it is a cloud infrastructure that is handled by single organizations or the company. The private cloud could be located at the either cloud provider’s data center or organization. Private cloud service is the best service to secure your network and the data.

In the public cloud, there can be multiple users’ datastore on a single server. So, if the server crash then your data can be a leak, and another user can also see your data. While using private cloud service, the Company or business takes the whole server on the rent so, except the company’s data, other data can’t be stored on that server. So, the private server is the best way to give respect to the privacy of your users.

Hybrid cloud

the hybrid word means combination. The hybrid cloud word suggests that it is a combination of the private and public cloud. This is the simple way to exchange the data between the private and public cloud.

In organizations and businesses, there can be 2 types of data. One is public which doesn’t need any type of security and another is private which needs privacy. A hybrid cloud allows you to store data at both places. You can store private data on your server location or public data to the cloud provider’s service location. 

Generally, the private cloud is an expensive option. So, you can decrease the cost of servers and increase the security of important data by using the hybrid cloud service. 


There is not too much difference between the multi-cloud and hybrid cloud. Multi-cloud also provides the same service as a hybrid cloud but it uses multiple data centers, servers,  hardware,  and storage devices.

These are all basic and most used cloud types. If you need to use a cloud service then you can choose it according to your requirements and budget. Here,  you can read about more cloud types.

Benefits to using cloud computing

Every new technology has its own benefits and cloud services have also.

Cost efficiency

While using the third party service of cloud computing you have to pay only renting cost according to your use. You have not to invest in building big data centers and servers. So, it removes all the capital expenses and that capital you can invest for your company’s growth. 

Even though if you invest some capital to build your own server then every day you need extra maintenance charge for cooling server, electricity and employers salary and which is equal to the charge of renting any server. 


The simple meaning of agility is quick. Cloud service allows you to upload any data to your network and download or access it from anywhere. It provides data accessibility from any location and any computer with your permission.  So, you can transfer lots of data in a couple of minutes from one location to another location.

Deploy globally

Using the cloud service you can deploy the apps or websites globally in any region in a couple of moments. After a successful deployment of the app on the server, you will get huge global traffic and which can help you to expand your business growth and revenue of the company. 

Only by using the app, you can share any resources with your global audience and attract them.

For better performance

Nowadays, third party cloud computing service provider company has huge data centers, servers, and hardware rooms. So, they maintain it day by day. They update the hardware regularly so your application or website will perform better. 

Even though, if the system crashes and one or two server fails then they can then transfer the load on the stand by the server. So, it can’t affect the performance of the application.


Once you have started to use cloud service, you don’t need to take the backup of the data. Cloud service providers regularly take the backup of your data so in case, the server fails and data loss occurs then it can be restored from the backup location. So, you can recover the data without any disruption.

Scalability and security

As you know third-party company handles big servers and many users data so they have fully secured networks. It is a very difficult task for any hackers to break that security network and stole the data.

Moreover, you are getting better performance, Global deployment, better speed of the application, Reliability at a very low cost. It shows that your business or IT capabilities can grow very fast. 

Types of cloud computing

Generally, cloud services divided into six categories. Infrastructure as a service (IaaS), Platform as a service (PaaS), Software as a service (SaaS), Mobile Backend as a service” (MBaaS), Function as a service (FaaS), Serverless computing. 

Generally, cloud service provides the use of hardware and software virtually (online). But it provides the permission to choose hardware, and data storage according to your need. Also, it provides flexibility to manage and control your resources. Here, we have explained to you only 4 broad categories. 

Infrastructure as a service (IaaS)

Infrastructure as a service (IaaS) contains system software, computer networking, computer hardware, and data storage, etc. IaaS provides you the above type of resources which is related to IT infrastructure. As much as you will use this infrastructure, you have to pay according to that. 

IaaS does not provide services like managing, controlling, and deploying the apps, database, and website. To install and manage the resources is the total responsibility of the cloud customer.

Platform as a service (PaaS)

The benefit of using the PaaS over IaaS is that customers don’t need to handle the database, web app, and software. This all things manage and control the third-party cloud providing service. WordPress hosting is the best example of PaaS. When you bought WordPress cloud hosting, you don’t need to manage the database and WordPress hosting. 

 However, it provides you access to the database so that you can also make changes to it. So, PaaS is one step ahead of the IaaS which provides infrastructure and manages your resources also.

Serverless computing

The serverless computing service company focuses on building your app or software. It focuses more on adding unique features to the app instead of controlling and managing the server and resources. Cloud provides configure your app and plan about to deploy and manage it. 

Software as a service (SaaS)

While using the SaaS you don’t need to concern about how system software or application controlled. Because all things from hosting your application to managing and controlling are done by the cloud hosting providers. You don’t need to pay rent for the infrastructure like storage system and server. The company will use its own server and host your application in every region. Your work is so simple. You have to use the application by accessing it from the internet. So, while taking the SaaS service just focus on how your application is working rather than how it is controlled.
