HOW CLOUD COMPUTING WORKS .. !!!

Cloud Computing   has been changing how most people use the web and how they store their files. It’s the structure that runs sites like Facebook, Amazon

and Twitter and the core that allows us to take advantage of services like Google Docs and Gmail. But how does it work?

Let’s understand what the term “cloud“ refers to.  The concept of the cloud has been around for a long time in many different incarnations in the business world. It mostly means a grid of computers serving as a service-oriented architecture to deliver software and data.What differentiates the cloud from the way those are set up is that the cloud utilizes the resources from the computers as a collective virtual computer.The cloud takes advantage of that a lot of the software that people use nowadays are completely web-based. For example, if you are hosting your website on a local server or from your PC, you must usually select a particular operating system (Windows/Linux/Mac), to determine what software you can run on that particular server. If your site is being hosted in the cloud, there is no need to do that. You can run Windows and Linux programs side by side.

How is that done?

To understand how does cloud computing work, imagine that the cloud consists of layers — mostly the back-end layers and the front-end or user-end layers. The front-end layers are the ones you see and interact with. When you access your email on Gmail for example, you are using software running on the front-end of a cloud. The same is true when you access your Facebook account. The back-end consists of the hardware and the software architecture that fuels the interface you see on the front end.

Because the computers are set up to work together, the applications can take advantage of all that computing power as if they were running on one particular machine. Cloud computing also allows for a lot of flexibility. 

Will it change the way we use computers?
Sure, most of us still use some version of Microsoft Office or Quickbooks that was installed on our computers, but even those kinds of software are now offering an online version that can be used instead. The possibility of being able to access your data and software wherever you need it makes this transition very appealing to most people.
