'Cloud' awesome in computing

 


'Cloud' awesome in computing

Technology has not only made our lives easier but has also provided a new dimension to the development of the country and the world with improvement in living standards. In today's era, humans are completely dependent on science and technology. No area is untouched by technology. This time in the 'Technology' column we will talk about the word 'cloud' which is often heard in computing, the word cloud in computing

What is the story? 

The word was first used in 1996, but even today, the word is a puzzle to most people. A funny video from a few years ago went viral on the internet in which a journalist asked a former Income Tax Commissioner what cloud computing is. The Commissioner of Income Tax had nothing to do with the cloud, but when asked the question was bound to answer. He responded in terms of his understanding. He said that cloud computing means storing your data in 'clouds'. He also outlined the limitations of this technology, such as 'It works well in the forests but where there is a drought, there are a lot of problems.

You must be smiling The general concepts of the technology are also low in awareness level and hence there is a need to continuously discuss them. Cloud computing has nothing to do with clouds. If the Internet had to be shown as a picture, how would you show it? Would you make a web on the world map? Perhaps it would be easier to show it as a cloud covering the world. 

The same cloud that was previously shown as a picture of the Internet in the form of an image or symbol. It eventually came into being literally in 1996 when the term was used in the internal documents of computer company Compaq. So cloud does not mean thunder or rain cloud, but internet. And cloud computing means the use of resources placed on the Internet for its digital work.

You must have seen offices or educational institutions in which the computers connected are connected to each other. The systems connecting them are called networks. There are also many server computers in this network, which have more storage and processing capacity than ordinary computers. You may know that other computers connected to the network can access each other and they can also access server computers in the network. For example, if there is a printer with the server, then you can send a print command from any computer in the network which will first go to that server and from there to the printer. Even if you do not have a printer with your computer, but you are still able to take a printout. Some offices also have email servers.

The email that you enter or send to your computer goes through the same email server.

Similarly, there are some application servers. Suppose that your computer does not have software like Microsoft Word or Photoshop, but they are placed on a server. When you need it, you can access this software through the network while sitting at your computer. 

One such situation can happen when a hard disk of a very large size is placed on a server and all the people in the office are instructed that you will not store all your files in your computer but in that server computer.

You must have understood this thing of computer, network, and server. Now you can use the resources of your computer as well as the resources of the servers placed on the network in almost the same way as they are in your own computer. This is network computing which is a very profitable deal. You did not have to install a printer with every computer, did not have to install software on every computer, did not have to install a large hard disk on every computer, and just by installing it in server computers, the work of the whole office was done. Money was also saved and control was also at one place, security was also high.

Now imagine if these server computers were put on the Internet instead of your network? Because the Internet is also a very large size network and you are connected to it. Will you still be able to use the resources of these servers? So this is cloud computing. That is, you are using such resources which are not on your computer but are present on the Internet. These resources can be the complete infrastructure along with computers, servers, and software. These are not available to you in physical form but are being provided as a service available on the cloud.

Today Internet connectivity has become so good that often you download files from the Internet in the same amount of time it takes to copy files from one place to another on your own computer. That is, whether you do some work locally or through the Internet, you do not feel any special difference. The resources you are using, whether you have them or are kept on the Internet, do not matter to you as long as your work continues smoothly. You have been doing this already.

When you check and send your email to Gmail, Outlook Mail, Hotmail, Rediff Mail or Yahoo Mail, etc. do you find any shortage anywhere? Of course not, however, all these email services work via the cloud. Even today, many offices have their own private email servers and the work of receiving and sending emails is done through special software installed in the computer. But you can do the same thing with your browser equally easily. 

This means that whether the work is done through the cloud or from your computer, there is no significant difference in their quality in modern times. You are doing many more such things through the cloud, which you probably do not realize. For example, going to the search engine, doing some search, translating from one language to another, changing the font of your documents (eg Kriti to Mangal), etc.

A fun example is Google Ad-Sense. If you have a website, blog or YouTube channel, etc., you can participate in the Google Ad-Sense program and then automatically start showing ads with your content. how did this happen? Neither you booked the advertisements, nor designed them, but still, the advertisements are coming on your website and you are also earning.

In fact, all this is being conducted on the cloud. Nowadays, many people go to websites like 'Canvas and design various types of cards, letterheads, logos, book covers, and advertisements, without the presence of any graphics software on their computers. Some people are editing online videos and some are making animations. All this is also amazing for the cloud, which has made the distance between online and offline irrelevant.

The resources on the cloud can be divided into three major parts - SAS (Software Edge a Service), PAS. (Stage as a Service) and IAS (Infrastructure as a Service). Software Edge A service means that you can use Microsoft Word, Photoshop, any video editing software, or similar software through the cloud without installing it into your computer. Many people use Google documents. It became the first category of cloud services. 

If you develop software but access the platform or components (parts) used in their development through the cloud, then that platform will be called Edge a Service. Similarly, if you use a comprehensive platform (which includes hundreds of types of software, hardware, and services), it will be called Infrastructure Edge A service, such as Windows Azure, Amazon Web Services, and Google Compute Cloud. Here you will be using and managing the entire computing structure of your institute or company through the internet. Today you started the company, today took the services and from yesterday the work of the company started.
