Cloud Computing. Concept behind it - (Azure - Part 3)

How many times you have deleted older files and folders, just to make space for new files and apps? What if you don’t have to do it from today onwards?

The concept of cloud computing is very simple. Imagine you are working with a very low end PC. For example, let’s say there’s no sufficient hard disk space. Even the processor, RAM and every other aspect of configuration is too basic. But you want to host your application that requires high memory, disk-space and bandwidth.

Here, the solution would be to connect your PC to internet. Connect to a super-computer, and host your application. Very simple. Isn’t it?

Taking it forward, this discussed, so called supercomputer, is nothing, but a vast network of machines, providing combined storage, memory and infrastructure. Lets see if this diagram will be able to explain it at high level.


It also takes its own backups at regular intervals and if one machine fails, another is swapped-in, without user knowing anything about it at all.

We’ll dive in more details in next post. Till that time watch dilbert on ‘Cloud Security’.
