Cloud computing is the distribution of computing services like servers, storage, databases, networking, software, analytics, and intelligence over the Internet (“the cloud”) in order to provide speedier innovation, more flexible resources, and economies of scale.

You usually only pay for the cloud services you use, which helps you cut costs, run your infrastructure more efficiently, and scale as your business grows. The best web app development company in Chennai uses cloud computing to develop, configure, test, and deploy any web application.

In other words, the cloud eliminates the need for local hardware. Maintaining a server can be time-consuming and complex for a business. Hardware and upkeep can quickly add up to a lot of money. The user only pays for the portion of the cloud that he uses with cloud computing. The service is responsible for the physical server’s load, security, and maintenance, among other things.

Types of Cloud Computing

Public cloud, private cloud, and hybrid cloud computing are the three basic types of cloud computing. Let’s take a closer look at the many sorts of cloud computing.

  • Public Cloud
  • Private Cloud
  • Hybrid Cloud
Public Cloud

A public cloud is a platform that makes resources such as virtual machines (VMs), applications, and storage available to customers remotely using the conventional cloud computing concept. Free public cloud services are available, as well as a range of subscription or on-demand payment models, including a pay-per-use approach.

Amazon, Microsoft, and Google are just a few examples of public cloud providers. These businesses provide services as well as infrastructure that is shared by all clients. Massive amounts of available space, fast data upload speeds, and increased bandwidth are all common features of public clouds, resulting in easy scalability. For software development and collaborative projects, the public cloud is frequently recommended.

Companies can build their apps to be portable, allowing them to shift a project from the public cloud to the private cloud for production. The majority of cloud providers bundle their computer resources into a service. Access to a completely virtualized infrastructure that provides little more than raw processing power and storage (Infrastructure as a Service, or IaaS) to specialized software programs that are simple to deploy and use are all instances of public cloud services (Software as a Service, or SaaS)

Pros of a Public Cloud
  • Easy scalability
  • No geographical restraints
  • Cost-effective
  • Highly reliable
  • Easy to manage
  • Cons of a Public Cloud
  • Not considered the safest option for sensitive data

A public cloud is a platform that makes resources such as virtual machines (VMs), applications, and storage available to customers remotely. Amazon, Microsoft, and Google are examples of public cloud.

Private Cloud

Private clouds are often located behind a firewall and used by a single company. For enterprises with strict regulatory requirements, a totally on-premises cloud may be the best option, while private clouds established through a colocation provider are gaining favor. Authorized users can access, use, and store data in the private cloud from any location, just like they can in the public cloud.

The distinction is that no one else can use or access those computing resources. Although private cloud solutions provide protection and control, they come at a price. Because the cloud owner is responsible for both software and infrastructure, this is a less cost-effective strategy than the public cloud.

Pros of a Private Cloud
  • High level of security
  • Great control on server
  • Easy Customizable
Cons of a Private Cloud
  • Harder to access data from remote locations
  • Requires IT expertise

Private clouds can only be used by a single company. Authorized users can access, use, and store data in the private cloud from any location.

Hybrid Cloud

Hybrid clouds are a mix of public and private clouds. They’re built to allow the two platforms to work together effortlessly, with data and applications flowing freely across them. A hybrid cloud model’s main benefit is its ability to combine the scalability of a public cloud with the security and control of a private cloud. Data can be safely kept in a private cloud environment behind firewalls and encryption mechanisms, then transported securely into a public cloud environment when needed.

This is especially useful in the age of big data analytics when industries like healthcare must adhere to rigorous data privacy standards while also deploying powerful AI-powered algorithms to derive relevant insights from massive amounts of data. Hybrid cloud architecture can be divided into two categories. The primary cloud for cloud bursting is a private cloud, which stores data and houses proprietary applications in a secure environment.

However, when service demand grows, the private cloud’s infrastructure may not be able to keep up. This is where the public cloud enters the picture. The public cloud’s computing capabilities are supplemented by the private cloud in a cloud bursting model, allowing the organization to handle additional traffic without having to buy more servers or equipment.

The second hybrid cloud model keeps most applications and data in a private cloud but outsources non-critical workloads to a public cloud provider. This is a common solution for businesses that require specialized development tools (such as Adobe Creative Cloud), basic productivity software (such as Microsoft Office 365), or CRM platforms (like Salesforce). Multi-cloud architecture, which incorporates various cloud service providers to satisfy a variety of distinct business needs, is frequently used here.

Pros of a Hybrid Cloud
  • Highly flexible and scalable
  • Cost-effective
  • Enhanced security features
Cons of a Hybrid Cloud

As used in both private and public clouds, the communications at the network level may be conflicted.

A hybrid cloud is an environment with the private and public cloud allowing data and applications to be shared between them. Google Cloud is an example of a hybrid cloud.

Cloud Computing Services

Cloud computing is a broad term that refers to a collection of cloud computing services that provide businesses with cost-effective ways to expand their IT capacity and functionality by allowing them to pay only for what they use, with the maintenance and other costs incurred by the businesses that provide the service being managed by the businesses that provide it.

Businesses decide where, when, and how they employ cloud computing to ensure dependable and efficient IT solutions based on their individual requirements. In this guide, we’ll look at three different types of cloud computing services, as well as the many deployment models that can be used in these settings.

Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service are the three most popular cloud computing services (SaaS). There is a clear distinction between the three services in terms of storage and resource pooling, but they can also combine to form a single cloud computing paradigm. 

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

One of the most essential cloud computing services, Infrastructure as a Service (IaaS), provides virtual storage space, network, virtual server, connections, operating systems, and data storage devices. It necessitates overseeing everything without having to buy and install hardware in the office.

Both the company that provides the infrastructure and the company that uses it benefit from this cloud service. It provides flexibility, reliability, and scalability, as well as eliminating the need for office hardware. Small and midsize enterprises searching for cost-effective IT solutions to support business growth can benefit from the IaaS service.

IaaS is beneficial to both because it is a fully outsourced service where the user only pays for the storage space used and is not responsible for maintenance or other charges because they are handled by the company that is outsourcing the service. It is available as a public, private, or hybrid infrastructure. 

Platform as a Service (PaaS)

As a service platform (PaaS) is a type of cloud computing service that provides a platform for users to develop, run, and manage apps without the hassle of setting up and maintaining the infrastructure that comes with designing and launching an app.

The infrastructure and software foundation is provided by cloud computing providers, but enterprises can design and run their own applications. Web applications can be created quickly and easily with PaaS, and the service is more robust and adaptive to support them. For firms with multiple developers working on a single project, the system is excellent and scalable.

Furthermore, because PaaS is built on cloud computing, which was defined earlier in the study, it allows for a lot of scalability by design. If your app will succumb, a PaaS can be handy if you desire a lean operations team. The most significant disadvantage of employing a PaaS Cloud provider is that these services may impose restrictions or trade-offs that will never work with your product.

Software as a Service (SaaS)

Unlike IaaS, which involves the deployment of software over the internet to multiple businesses who pay via subscription or a pay-per-use model, SaaS cloud computing involves the deployment of software over the internet to various organizations who pay via subscription or a pay-per-use model. By having the program operate on the vendor’s computers, SaaS allows the cloud to be used for software design.

It decreases the burden of maintenance, upkeep, services, and operations. It’s a great tool for CRM and apps that require web or mobile access, like mobile sales management software, Gmail, and Salesforce. Because SaaS is managed centrally, organizations don’t have to worry about keeping it up to date, and it’s great for short-term projects. 

Why Cloud Computing with Example?

Let’s look at an example to see why cloud computing is so popular. A young entrepreneur made the decision to start an internet company. As a result, the person creates a server on his own computer and follows all of the necessary procedures to make it work. As time passes, traffic increases and his system becomes unable to handle the additional strain.

The entrepreneur now needs to buy server configuration and hardware in order to set it up. Everything was fine until the server load reached its maximum capacity, at which point the server issue became a traffic bottleneck once more. What options does he have at this point? He is compelled to purchase another server unit, but this necessitates additional room, a cooling device that allows it to operate in hot environments, and support and maintenance personnel.

He must also concentrate on adhering to the most up-to-date server protocols, maintaining the fastest server settings, and ensuring that none of his servers fail! This necessitates the presence of a support team responsible for ensuring that no servers fail. This will help entrepreneurs to get rid of the server maintenance cost, space, employee cost, service cost, etc and they can focus on their main business. 

Advantages of Using Cloud Infrastructure

In any IT environment, a cloud is strictly considered an upgrade over traditional options. Cloud storage provides the following massive advantages:


Eliminated capital expenses of maintaining and running on-site data centers, cooling, power, data center management experts, etc.


Cloud providers are usually huge and well-established companies. As such, server speeds are guaranteed and are usually much faster than any on-site solution.

Global Scale 

No matter where your business takes you, cloud services have you covered! Optimized resource allocation based on your usage allows for perfect movement across geographic locations.


Time saved on IT services for the on-site upkeep of servers can be used by the company in more productive tasks. Not just this, but IT teams are not needed to reduce hiring costs!


The largest cloud services often leverage worldwide networks of very secure data centers. They are kept updated to tackle the latest IT security threats and maintained by the best cloud architects. They have the luxury of economies of scale as well to deliver unmatched performance.


With stringent policies, strict protocols, and global teams working on the security of the cloud, it is one of the safest places you can keep your data!
