Cloud Computing



Cloud computing technology is a very popular technology nowadays. Lots of people and companies use this technology to make easy their work. Some people use this technology even without knowing that they use this technology. Let’s understand clearly what this technology is and how it makes computing easy/beneficial.


Let assume you have an organization and there are bunch of computers. When you need to install same software for a number of computers then there may be many constraints. Sometime there are legal policies that ask you to pay them a large amount of money to install for a bunch of computers also sometimes it may be very time consuming task to install individually. 

The most important/considerable fact is that the computers may not be compatible with the software that you are going to install (hardware, operating system may not support / ram, video card, processor is not enough).  If you still need to install under these conditions definitely you need to upgrade your computers for the installation of new software. In this case cloud computing come for your rescue.



In cloud computing technology, the software/application that you need to use is not installed into your computer. So where is it   ???  It is installed into the cloud computing server. What you have to do is just logging into the server and use it.  In this technology your pc does not need to have high performance hardware or any specific operating system for the application. You just need an internet connection and a normal pc to log into the server. All the processing parts of the software are executed in the server. When you give an input from the keyboard or mouse that command directly sent to the server and that command is executed on the cloud server. so you can use software in the servers as they are in your PC.



Advantages of cloud computing

  •  Do not need to waste a large amount of money for hardware
  •  Operating system independent
  •  Easy to handle : The total software is stored in servers therefore space of your computer, memory usage and processor usage is saved
  •  some PC based applications can be used even from a mobile phone

Disadvantages of cloud computing

  •  Information security and protection                                                                                                                                                    When some very private and important data are stored in servers sometimes it can be stolen or  corrupted data (but nowadays these things are happened rarely)

  •  Servers do not support lots of software                                                                                        Cloud servers support only for popular and mostly used software so sometimes they will not provide service for some software

 Popular applications which use cloud computing technology

  •  Facebook

Cloud Gaming




            Cloud gaming is one of the most popular technology in the world for game playing. The words “cloud gaming” may little bit weird for the people who are not much involved in the IT sector. But the simple meaning of “cloud gaming” is that you can play complex modern games without having expensive hardware parts. (Simply, even though system requirements are not satisfied you can play games from your own pc) 



          Think for a while, nowadays when someone needs to play a modern game definitely he should have a high performance pc.  Many people do not have high performance pcs due to their cost.  Therefore this new technology helps gamers to play modern new games by their own ordinary pc without fitting new hardware components.  (Amazing isn’t it :) )



Ok now let’s learn a bit about how this method works. 

This is like video streaming. As an example when you are watching a video on YouTube it is called video streaming. So the game is also played like a video streaming method.   When you play the game it is actually executed on “cloud gaming servers” not on your pc. When you play it all the visuals of the game are streamed in to your computer. When you give instructions/commands using your input devices mouse, keyboard or joystick those commands are directly sent to the cloud gaming server and at the server they are executed. So the game is originally played on the servers and you are just watching the videos.





  Cloud gaming technology has two methods which depend on the speed of the internet connection which are  video streaming method (for speed connections) and file stream method (for low speed connections). So you can play these games from a low speed connection too.

Advantages of cloud gaming


  •       No need to pay for additional hardware to play games
The game run on cloud gaming servers, so just having basic hardware is enough to play modern games.

  •        You can play games from any operating system
Normally lots of games are restricted to a specific operating system. So people who are using other operating systems cannot play the game. But in this method you can play from any OS which support this service.

  •   You can play it instantly and can save space
When you are going to play a game in traditional/usual way first you have to download and install the game with wasting a huge amount of space in the hard disk (number of GBs). But now when you are getting the service from a cloud gaming server you can easily play a game you like.

  •    Can play it even in mobile phones
Cloud gaming technology is extended for mobile usage therefore you can play many games using your smart phone.
