What is Cloud Computing?

ccIn my many years in Information Technology Systems, I’ve heard many terms.  The one that many people have heard of is “Cloud Computing”.

So, what is Cloud Computing?  According to the Oxford Dictionary, Cloud Computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

If you need more of an explanation keep reading.

Let’s start with Technology.  You might think that technology is full of new things and Cloud Computing must be one of these new things.  We to be more direct Cloud Computing is a new concept and design of technology that has been around for many years.  So, Relax.

The Internet plays a big roll “Cloud Computing”.  As the internet gets faster and storage get cheaper the capabilities of “Cloud Computing” come to life.  The computer, tablet or smartphone in your possession gets all its information from the Internet or from the “Cloud”.  Complete “Cloud Computing” will hold nothing on your device’s hard drive or memory and all information and services (programs) you are running is accessed from the Cloud.

Several years ago I was working on systems that were called “Thin-Clients”.  This were early forms of Cloud Computing.  Thin Clients were desktop computers that contained the basics of operating systems (to start the system) and a networking component (to connect it to the internet).  All the application (programs) and data were stored on the server (via the internet).  The processing of data (programs were run) locally but the computer didn’t have much of a hard drive (it didn’t need it).  It was ahead of its time and really neat, but it didn’t get as far as Cloud.

Underneath all the is the internet.  The same internet that was developed in the 1960’s.

Now you know and can explain what “Cloud Computing” is.
