What cloud computing is ?

Hello friends..!!!

You must have heard the term cloud computing many times.

So in today’s thread I am giving brief information about what cloud computing is.

(Part 1 )

The concept of cloud computing has become in the market for a long time.

In our day life we use the cloud, when we access a mail or watch videos on OTT platforms like Hotstar Netflix, list to song on Spotify, here we are using the cloud.

Structure of hardware or software through the Internet The concept of providing any service to customers with any service to multiple customers is called cloud.

In short, the cloud is a confluence of three things. 

1. Providing services such as computing or storage.

2. Many people use community resources.

 3. People reach out to these services through networking.

The foundation of cloud computing was laid almost 70 years ago i.e. between 1960s.

It was John Myakarthi who first used the term artificial intelligence in 1961 who predicted that one day computing would be sold like a computer

IBM created a computer system in 1967 that would allow multiple users to use computer resource stocks simultaneously.  Personal computers did not exist during this period so this terminal was not that smart.

This meant that it did not have a CPU or much larger memory.

They had enough memory to temporarily store user-typed data, but the data was immediately sent to the computer where it was displayed on the screen and processed there.

IBM created IBM 360 and IBN 370 making it possible for many people to work on one computer.

Within a short period of time, it was proposed to connect these terminals to the computer from a distance

The company had to acquire a personal computer separately for almost every employee, along with that computer, they had to take all the software products needed by the computer like word processing, operating system software, and create a computer network.

All this would add server to the company. Staff were required to maintain & program their hardware & network. All these used to take a lot of space and a lot of time. Software licenses and hardware also cost a lot because they cost money

In any big company, one big computer was required for each department i.e. one for purchasing, one for processing, one for accountant.

On each of these computers there are applications e.g. Purchasing, production, accounting work. Similarly, all the data required for the application was placed on a disk connected to that computer.

All people used that application through the personal computer provided to everyone in that account.

And the data required for that should be accessed as per the permission given to them

Then came the concept of data center.

In a data center, the company sets up a large data center in its own compound and can hold together all the computers required by all the accounts of that company as well as the applications and disks that run on them.

Now every user had only one personal computer and all these computers were connected to the computers of that data center.

The data center reduced the space required because all the computers, networks and software, were all three in the compound.

And the data center also reduced costs slightly but the reduced cost and space issue had not diminished that much.

All these shortcomings were filled by the concept of cloud.

The Internet, which came in the nearly 90s, soon reached its peak.

In 1991, more than one million computers were connected to each other, making the client server model used in the Dotcom and e-commerce revolutions.

In this, the customer of the website could only see the front end and the server would be somewhere far away i.e. the customer of the business would see the client side and all on the other side i.e. the remote place.

The term cloud was first coined by Professor Ramnath Chellappa in the late nineties.

In cloud computing, the term cloud is used metaphorically to refer to a customer using the services of a cloud computer just as we do not see things hidden in clouds

There is no telling what is going on behind the scenes.

The twenty-first century took a turn for this idea to become a reality.

In 2002, the first cloud in the virtual universe’s sky, Amazon Web Services (AWS), came into existence.

Companies that provide cloud services buy many large servers and connect those networks to each other.

These servers are equipped with many large and capable hard disks.

These servers and disks not only have operating systems but also software packages required by different users.

Now this company can lease cloud to many other companies.

So every user company does not have to keep all its own network, hard disk software and maintenance staff,

Instead of buying so much software and hardware, the rent required for the cloud is cheaper and the back cut is reduced.

The company’s location is also saved by cost.

Google, Facebook are the companies that use this cloud.

All the mails of everyone who are millions of users of Google are kept by Google on the cloud.

The conversations we have with each other on Twitter are also kept on the cloud

Currently leading cloud service companies are AWS, Microsoft Azure, Salesforce, Google cloud.
