What is Cloud Computing?

You may have heard this word too many times, but do you know what is Cloud Computing, why is it getting heard so much these days. As we know that computer network technologies have grown a lot in the last 20 years.

Ever since Internet (the most popular computer network) has revealed its existence, there has been a lot of advancement in the field of computer network and there has been a lot of research in the field of technologies like Distributed Computing and Cloud Computing.

These technical terms are the concept of both Distributed Computing and Cloud Computing are often the same, there are some inequalities in both. So if you want to understand about Cloud Computing then you must also understand Distributed Computing.

Global Industry Analyst tells that this global cloud computing service market will become a business of up to $ 327 billion by 2020. Nearly all companies are using Cloud Computing service in today’s dore, be it directly or indirectly.

For example, if we talk, whenever we use the service of Amazon or Google, then we are storing all our data in the cloud. If you use Twitter, then you indirectly use cloud computing service.

Distributed Computing and Cloud Computing are both so popular because we needed better computing networks so that our data could be processed faster. So what is cloud computing today? You will know more about this in this article.

So, let’s start delaying and know what this Cloud Computing is? And why is it becoming so popular.

Talking about Cloud, it is the design of a large interconnected networks of servers that have been designed to deliver computer resourses. And there is no concept of precise location where data is coming from and where it is going.

If I say in easy language, if a user uses it, then he will feel that he is using a huge formless computing power, in which the user can do everything from his email to the mapping of mobile application according to his need. .

There is nothing like saying “The Cloud” in the language of Business. Cloud Computing is a collection of licensed service that is provided by different vendors.

Cloud service replaces them with different products in place of technology management and technology acquisition and these products are managed from elsewhere and one thing they are active only when it is needed.

What is Cloud Computing?

If someone provides a service through the Internet, it is called Cloud Computing. This service can be anything like Off-Site Storage or computing resources.

Or simply say, Cloud Computing is such a style of computing that massively scalable and flexible IT-related capabilities are provided as service with the help of Internet Technologies.

Facilities like infrastructure, platform, application and storage space are available in these services. In this, the users use the services according to their needs and pay the money for the same services that they use. For this, they do not need to build their own infrastructure.

Nowadays there is a lot of competition in the world and in this way people need service on the Internet at all times, without any delay. If an application ever freezes, then there is a lot of dissatisfaction among the people. People need the service they need 24/7.

To fulfill this requirement, we cannot emphasize on old mainframe computing, so people used Clored distributed computing technology to solve this problem. Because of which big businesses started doing all their work very easily.

For example, Facebook, which has 757 million active users and sees about 2 million photos daily, around 3 billion photos are uploaded every month, 1 million websites use Facebook to do 50 million operations per second.

In such a situation, the traditional computing system cannot solve these problems, rather we need something better that can work. Therefore to do such computing, Cloud Distributed Computing is the need of the hour.

Examples of Cloud Computing

  1. YouTube is a great example of cloud storage that hosts video files of millions of users.
  2. Picasa and Flickr which hosts digital photographs of crores of users on their server.
  3. Google Docs is another great example of cloud computing that allows users to upload their presentations, word documents, and spreadsheets to their data servers. With this, there is also an option to edit and publish those documents.

Characteristics and Benefits of Cloud Computing

If seen, Cloud Computing has many attractive benefits that are going to be very useful for businesses and people. There are 5 main benefits of cloud computing:

Self-service provisioning

End users can do any work according to their need which they need most. With this, the traditional needs are IT administrators, who used to manage and provision your compute resources earlier, and they are not needed anymore.


Companies can also increase and earn according to their computing needs. It is a benefit that as before there was a lot of investment on the local infrastructure, it has completely stopped now, it benefits the companies a lot.

Pay Per Use

Compute resources are measured at a granular level. So that users only have to pay for the resources and workloads they use.

Workload Resilience

Cloud service providers often use redundant resources so that they can get resilient storage and with it they can continue the important work of users who are famous in multi global regions.
Migration Flexibility: Organization can transfer some workload from one cloud platform to another according to their need, without any difficulty and automatically which saves money also.

History of cloud computing

If we talk about cloud computing it was born in the tens of 1960s. When the computing industry assumed computing as a service income utility based on its potential benefits. But earlier computing, connectivity, and bandwidth were both lacking due to which it was not possible to implement computing according to a utility.

This was not possible until the availability of Internet bandwidth was achieved in a large scale by 1990. After which it was possible to think of computing as a service.

In 1990, Salesforce successfully implemented commercially enterprise SaaS for the first time. After which AWS did in 2002, which provided many services like online storage, machine learning, computation.
Today there are many mega providers like Microsoft Azure, Google Cloud Platform which together with AWS are providing cloud-based service to other individuals, small business and global enterprise.

Cloud Computing vs. Distributed Computing

1) Goals

If I talk about distributed computing, it provides collaborative resource sharing by connecting with other users and resources.

Distributed Computing always tries to provide administrative scalability (number of the domain in registration), size scalability (number of processes and users), and geographical scalability (maximum distance between the nodes in the distributed system).

While speaking of Cloud Computing, it believes in delivering service in the on-demand environment so that the targeted goal can be achieved. Along with this it also believes in providing more scalability and transparency, security, monitoring, and management.

Services in Cloud Computing are delivered with transparency without physical implementation in the Cloud.

2) Types

Distributed Computing is divided into three types

Distributed Information Systems
The main purpose of these systems is to distribute this information through various communication models across different servers such as RMI and RPC.

Distributed Pervasive Systems
These systems are mainly made up of embedded computing devices such as portable ECG monitors, wireless cameras, PDA’s, and mobile devices. These systems can be identified to compare their instability to any traditional distributed systems.

Distributed Computing Systems
In these types of systems, the computers that are connected in the network are interconnected by message to track their activity.

Cloud Computing is divided into four types

  1. Private Cloud
    It is such a cloud infrastructure that dedicatedly hosts all the applications of a particular IT organization so that its complete control is over the data so that the security is unlikely to breach.
  2. Public Cloud
    This type of cloud infrastructure is hosted by other service providers and which are later made public. In such a cloud, users do not have any control nor can they see the infrastructure. For example, both Google and Microsoft own their cloud infrastructure and later give access to the public.
  3. Community Cloud
    This is a multi-tenant cloud infrastructure, in which the cloud is shared between other IT organizations.
  4. Hybrid Cloud
    These are Combination 2 or more different types of clouds (Private, Public, and Community) only then Hybrid cloud infrastructure is formed where each cloud remains as a single entity, but all the clouds combine to form multiple deployment models, which make the flow retarded. Huh.

3) Characteristics

In Distributed Computing, tasks are distributed between different computers. So that computational functions can be performed at the same time.

Cloud Computing Systems use the on-demand network model that provides access to shared pool of computing resources with the help of Remote Method Invocations.

Types of Cloud Computing | Types of cloud computing

Cloud computing can be mainly divided into three parts: IaaS, PaaS, and SaaS.

Cloud Computing Models

  1. Infrastructure as a service (IaaS): These services are self-service models that are used for monitoring, accessing, and managing the infrastructure from a remote location. Examples – Servers, Firewalls, Routers, CDN
  2. Platform as a service (PaaS): It provides a line of self-service modules for software developers to manage the computing infrastructure from centralized IT operations. Examples – Email services: Gmail, Outlook.com
  3. Software as a service (SaaS): SaaS accesses the web to deliver applications that are managed by third-party vendors and whose user interface can only be accessed from the client.

Application Building: Google App Engine, SAP Hana, Cloud Foundry

Cloud Computing has changed the entire computing industry. It has completely changed the look of businesses and the IT infrastructure as well. It provides a lot of benefits for hardware and software, which seemed impossible only a few years ago.

Now a virtual machine needs just a few minutes to run. Cloud Computing has changed the attitude of companies and businesses. It has now become the first choice of all because if someone does business properly with complete planning, strategy and budget, then he will surely get success.

And scientists are doing more and more research to make it better.

Note – The real Cloud Computing is that “You can access any of your data from anywhere in the world” eg G-Mail, Google Drive, etc
