A 5 minute presentation about cloud computing. Simple and easily understandable.

2. What is the ?
ALICE: It’s a visible mass of condensed watery vapor floating in the
atmosphere.
BOB: I don’t think this presentation is about that cloud.
ALICE: Oh, then what is it about?
BOB: I don’t know. Let us find out.

3. Imagine that you have a dog named “Max”.

4. But you’ve only got one photo of Max.
And because you love your dog so much you’re
worried you might lose this photo.

5. So you upload the photo to one of your favorite photo websites
like Picassa or Facebook.

6. And without realizing you just started using the cloud.

7. Now the photo of Max lives up on the cloud
until you need to look at it again.

8. You log on to Picassa or Facebook, and there’s Max.

9. You can see Max from where ever you want.
From home, from work, or even on your phone.

10. But is the photo of Max floating around in the sky?
No, it is stored in a secret warehouse which is full of computers.
These warehouses are called data centers or server farms.
And these data centers are present all over the world.

11. It is difficult to know where exactly the photo of Max may be
once it’s in the cloud.

12. Because it may be present in several warehouses, all at once.

13. Why do we do this?
You only have one photo of Max, which is saved on your laptop.

14. What happens when your laptop breaks? Or you lose your data?

15. You lose the only photo of your lovely dog.

16. But when Max is in the cloud, he’s stored not just at one place,
but all over the place.

17. So you are less likely to lose him.

18. What is the ?
The cloud is the internet, or a network of servers.

23. Computing as a Utility
Availability of power, water and electricity as utilities provided the industries
with the privilege of what it needed and when it was needed. It also allowed
the industries to pay for the consumed amount of utilities only.
Now with power, water and electricity, computing has also emerged as a utility.
And this has been made possible by the cloud.

24. Computing became a resource that could be switched on and off.
Users consume and pay for as much as is needed, when it is needed.
This is the essence of cloud computing.

scalability and reliability of systems…

27. ALICE: Oh…, so that’s what the cloud is.
BOB: Yeah!

Damn!
