Cloud Computing: What Is It?

Cloud Computing is the technology that allows you to use applications or services that are independent of your computer or device. Both the programs and their data do not depend on your computer; they are on the Internet, in what we call The Cloud. No, it really isn’t something new. Surely for years, you have connected to your bank online or that you buy your trips on a website.

The bank provides you with a service from the Cloud years ago. But then what has changed for us to talk about Cloud Computing?

The difference is in power and the things that today can be done in the cloud.

The difference is in the programs and software. We will give some examples:

Before, to use a text editor, you had to install a program. Now you can edit text or use spreadsheets directly in the cloud, and also the files remain in the cloud for you to edit from any place or device.

Before, to store files, you had to use your computer’s hard drive. Now you can use a storage service, and your files will be available from anywhere and from any device you use, your computer, your mobile or your Tablet.

But why the hell is a revolution?

There are many reasons. To begin, we have to understand that the old application consumption model had many limitations, especially for companies and professionals.

The old software model had important limitations, such as:

1.Limited capabilities. Both in storage space and in execution speed. In the end, everything was small.

2.The applications were installed one day, and in time they remained old. We had to install a new version.

3.Rigidity of the model. There was no payment for consumption as it happens with Cloud Computing. Full programs and licenses had to be paid forever.

4.Vulnerability to local problems. The breakage of the computer where the program was and its data could mean the total loss — also viruses and operating system problems.

5.Absence of ubiquity. Programs installed on a computer were only available on that device. People want to have their programs and their data accessible from anywhere.

Ok, in the end, why is it considered a revolution?

The first is because it overcomes all the limitations we have described above.

The second is that it makes available to any services that until recently were unthinkable.

Cloud computing allows you to have the power and capacity that were previously only available to large companies or institutions.

Let’s turn to an example again.

Let’s imagine that we need a translator of texts in several languages before we had to buy a program that we installed on our computer, of course, this limited us to what we had bought.

Now imagine that in Japan they have a computer the size of a bus that turns out to be the best translator in the world with Artificial Intelligence.

Of course, if you want the best translator, you will not have to buy a computer like that of Japan, which is worth several million and that does not fit in your home.

There will simply be an application in the cloud that connects to that computer, and you can do translations by paying only for the amount of translated text. That is Cloud Computing!

Where is that cloud?

Well, that cloud we talk about so much are computers that reside in places called Data Centers or Datacenters.

They are entire buildings full of computers tucked into special cabinets called Racks. Each cabinet or cabin can have more than a dozen servers. A server is a computer with a high capacity, and that is able to provide services on the network.

Datacenters like the one we show are not something new either. Large companies and governments have had them for decades. What Cloud Computing does is provide that power to the general public.
