The Infrastructure Behind of Cloud Computing

A draft about Cloud Computing. Have you heard about Cloud Computing, haven't you? I think so... But, if you do not work with Information Technology, I think you do not know many details about the structure that companies that are offering this technology has to have inside their Data Centers.

**Note: This post was translated from "Os bastidores da nuvem", writen by Gilberto Mautner and published at "Info Blogs".

Ok, let's go ahead...
To create an Internet Service Provider based on Cloud Computing, or something like this, the companies need to have many computers in their Data Centers, but these computers cannot be simple machines, I mean, these computers must be super machines. They are the Server Machines!

To be a Server Machine, the computer should hav more powerfull processors, much more memory, and much more disk space.

To see one of many models of actual Servers, Click Here.

Server Machines, not as many people think about, do not need a keyboard and a monitor to each of these one (of course, there is exceptions, in case of maintenance, for example.). Because of it, commonly they are stacked in furnitures called “Racks”, looking for to put as many machines as they can. If you want to see an example of it, Click Here.

“Racks”, how it must to be, are put in longs passageways, as we can see right here

Cloud services, as many of we know, must to stay always available, I mean, they must to stay on line 24x7. They cannot be turn off or stay unavailable across a minimal period of time, even if energy get down. Because of this too, Data Centers has in their infrastructure, for example, diesel generators, to supply energy during a period like that.
It is too important that, in many cases, there is Redundancy of Generators in most of companies, in other words, if one of these generators get down, the other start to work immediately.

Another thing, related to energy and generators; Data Centers must to keep diesel reserves to garantee the energy during a long periods of time, supplying power to generators. Problems like blackout can happen, as well as we saw in november of 2009. We can see an Underground Tank here, like an exemple. This tank has 30.000 liters of capacity. A tank like that can provide energy by 7 days, without us charge it again.

Another important components are the “No-breaks”. As well as we can see, these components are responsible to keep the energy up in the machines, even during a short period of time to the generators to get started to work, what happen commonly after a few seconds, in case of energy problems or somethings like that.

There is some equipments with removable batteries, which is really sofisticated, that allow us to change one or another battery, in the case of problems, but without to have to stop all the equipment, I mean, some no-breaks use the hot swap system.

To increase much more the services quality, looking for to keep the enviroment always up, the most of Servers have two or more independent outlets and each outlet is plugged on independent circuits, in other words, it is plugged on in diferent no-breaks.

Untill now, we have just talked about how is important to keep the energy working up among the Servers. But it is not everything!

The processors, the CPUs, I mean, the “mind” of the machines, installed inside the Servers get too hot.
Why does it happen? When you do a request executing a software, a lot of informations are send through the system. These informations are transformed in eletric energy, running up inside to the CPU core. To solve this question, which we can see like a problem, there is many ways, many techinics.

Dangerous problems or Disasters, if you do prefer, can happen at any moment inside the Data Centers. The most normal situation, about this issue, are wildfires. Its because of the high level of eletric energy running over the place. The companies must have a professional infrastructure (and tools!) to eliminate something like this.

Well, as well as we can see a little bit through at this post (and this! ;-P), the enviromental behind of Cloud Computing must be really well prepared. It seems like an industrial infrastructure. About the software, this enviroment is beyond of Operational System, network and things like these. Thermodinamic, chimical reactions against wildfires and so on.

Some phrases with new words. (ESL)

I feel that I need to increase my english vocabulary. And it's right because I study this language and I want to have a fluent english. Ok. But how to do it? If you are an English Student as me, I must know that this part is one of de most difficult thing: Really learn, I mean, record in our mind some new words to thinking in use those naturaly. Some teachers say, and I believe in them, that you need read a lot and write double that you actualy do! When you do it, read, you know new words. When you write, you record those new words. It's like our brain works. So, to practice this part of my studys, I'll write some new words that I always listen to in news a read in books and magazines and after this, I'll write some short phrases with these words. If you want to do it too, feel free! It's really really. Ok, so, let's get started! The words that I chose for now: - Deep; - Overwhelm; - Overwhelming; - Struggle; - Threat; - Harsh; - I feel...

We have to understand before to be understood!

Image
Everybody have their own reasons to make some things, to complain about some things, but we don't understand those attitudes everytime. We see people talking a lot bad things, sometimes bad words,,, It's normal, We do this! We complain a lot and in the most of the time we do it because of silly things. But what we do not do is; Stop ourselves and look inside of each other, inside of the heart of each other and try to understand the root reasons of those things, to main reason of those attitudes! It's really hard, i know! But I think that we can change! I think that we can do everything better! I think that we can treat everyone better! I ain't a perfect person, of course not! I make many mistakes, many, many mistakes... But I have in my mind that what I have to do, I mean, I always trying to think before take some actions, and I guess that in the most of the time I'm doing right things... Well, I got the inspiration to write this post because I receiv...

The world is upside down, but we must keep going!

I decided to post a picture of me smiling just because I want to be positive, but the truth is that the entire world is upside down nowadays, literally! Maybe you're aware of it, but if you don't for any reason, keep reading, I'll try to explain a little bit of what is going on... First, because it's the real deal now: There is a freaking pandemic going on here in our world called COVID-19 , or commonly called as Coronavirus. That freaking disease already not just infected millions of people around the world, but it killed more than a million people globally and it is still killing dozens, hundreds, sometimes and in some places thousands per day!! Crazy stuff... It is a very, very contagious disease, it is a very dangerous situation.. The World Health Organization  along with some of the biggest companies in the world is trying to understand and resolve the root cause of that disease, but it's not just all new to the world, but as I said, it's dangerou...
