What is Cloud Computing?
Cloud Computing is a network of remote servers hosted on the internet for storing and retrieving data. The cloud provides a number of IT services such as servers, databases, software, virtual storage, and networking, among others. In layman’s terms, Cloud Computing is defined as a virtual platform that allows you to store and access your data over the internet without any limitations. 
Companies that offer all the services mentioned above are called cloud providers. They provide you with the ability to store and retrieve data and run applications, managing them through configuration portals. Two of the best cloud providers available today are Amazon Web Services and Microsoft Azure.
Now that you know what is cloud computing, let’s see what are the benefits of cloud computing.

Benefits of Cloud Computing
Cloud platforms offer some significant benefits today, which are driving businesses to adopt Cloud Computing. Those major benefits include:

Cloud Categories Based on Deployment Models

1. Public Cloud

In a public cloud, everything is stored and accessed through the internet. This deployment system allows anyone with proper permissions to access some of the applications and resources. The most exciting part about the public cloud is that you own none of the components present in it, be it the hardware, software, or application. All the components here are managed by the provider. Amazon Web Services and Microsoft Azure are two prominent examples of the public cloud.

2. Private Cloud

A private cloud is used exclusively in organizations, which they can run locally or choose to outsource it to other cloud services providers. This infrastructure runs strictly on a private network, which means that people present in the network can only access it. VMware cloud and some of the AWS products are some of the examples of a private cloud.

3. Hybrid cloud

It is probably the fascinating form of Cloud Computing that contains the functionality of both public and private clouds. Organizations using the hybrid cloud can choose to keep some of their data locally and some on the cloud. NASA is the best-known example of an organization that uses a hybrid cloud. It uses a private cloud to store sensitive data and uses the public cloud to save and share data that can be viewed by the public worldwide.

Cloud Categories Based on Service Models

1. IaaS (Infrastructure as a Service)

This category consists of IT infrastructure that you can rent from a cloud provider on a pay-as-you-go basis, including servers, networks, and others. The best part about this service is that you have access to the services you provisioned, and some grant you root-level access as well. EC2, or the AWS Elastic Compute Cloud, is an excellent example of IaaS.

2. PaaS (Platform as a Service)

In this model, you are supplied with a pre-built platform from the cloud providers, where you can deploy your codes and applications. You only need to manage the codes and the applications, not the infrastructure. AWS Elastic Beanstalk is an example of a PaaS cloud.

3. SaaS (Software as a Service)

Here, the cloud providers offer you the end product, which could be an application or software that you can buy directly on a subscription. As a part of this service, the client maintains control of the software environment but does not maintain any equipment. There are some products of AWS and Microsoft Azure that provide SaaS.

Types of Cloud Computing

Cloud Computing is multiplying, resulting in it being classified into several different categories. However, out of various categories, there are six that stand out. These six categories are further divided into two parts: the category of cloud-based deployment and the category of cloud-based services. 

Cloud Computing is divided into three categories based on deployment, including:

  • Public cloud
  • Private cloud
  • Hybrid cloud

The remaining three categories are divided based on the services they offer, including:

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)

Now that you have a better idea of what the cloud categories are let’s learn more about them in-depth.

Difference Between IaaS, PaaS, and SaaS

Full-FormIaaS is an acronym for Infrastructure As A Service.PaaS is an acronym for Platform As A Service.SaaS is an acronym for Software As A Service.
AccessThe IaaS service provides its users with access to various resources like virtual storage and virtual machines.Using the PaaS services, users can get access to a runtime environment (for the development and deployment of applications and tools).The SaaS services give access to all of their services to the end-users, where it’s application hosting, storage, or any other services.
Technical UnderstandingA user requires technical knowledge to make use of IaaS services.One must acquire the basic knowledge of the concerned subjects to understand the setup of the PaaS services.You don’t need to know any technicalities to understand and use the SaaS services- the service provider can handle everything.
Used ByThe network architects primarily use the IaaS.Developers mainly make use of PaaS.An end-user generally uses SaaS.
ModelThe IaaS is a service model. It functions to provide various visualized computing resources all over the internet.PaaS is a cloud computing model. It mainly delivers the tools required for developing various applications.SaaS is a service model for cloud computing services. They mainly host various software and make them available for the clients.
PopularityIaaS is very popular among researchers and developers.PaaS is very common among developers who mainly focus on app and script development.The SaaS services are very common among consumers and companies for networking, sharing emails, files, etc.
Cloud ServicesVCloud Express, Sun, Amazon Web Services.Google and Facebook (and other search engines).Google and Facebook apps, MS Office Web.
