This video explains how cloud computing is becoming essential to be competitive, to be green, and to enable innovation. It is produced and presented by Christopher Barnatt, author of "A Brief Guide to Cloud Computing", and Associate Professor of Computing and Future Studies in Nottingham University Business School.

nice cooling towers.

[explainingcomputers]

@ndyt Yes, I spent a nice morning filming those!

your broadband must be brilliant, my internet will only run about 50% of the time!

[explainingcomputers]

@VTOLAircraftMad My broadband certainly holds up pretty well -- I think it has been down once for less than a day in the last few years. I do live close to an exchange though.

what is the security/privacy of data? they data of any organization is in the hand of some one else... no matter what they the say or Privacy Policy ... can they say no to intelligence agencies? govt? to there owners? who use data to for there own interest...  to me cloud computing is rubbish...

[explainingcomputers]

@originative Yes, security is an issue. However, the large, reputable cloud vendors have a very great interest in maintaining good security. This means that security becomes a key aspect of their business, in turn meaning that security is often improved by migrating to the cloud as many companies do not give security a high enough priority when running their own IT. I'm not saying there are not legitimate concerns. However, pragmatially most of us long ago sold our data souls to the Internet.

@satriani005 I'm running a home-built PC with a 2.8GHz Core 2 quad processor and 2GB of RAM. This is currently running Windows XP. The software used to make the video is primarily Premiere Pro 1.51, After Effects 6.5 and LightWave 9.2 for the CG. Why YouTube makes such a mess of my audio I struggle to understand . . .

I see this of being to great benefit to businesses looking to cut IT costs. For personal use, I don't believe cloud computing will catch on. What would be cool though is having a powerful home desktop double as a personal cloud server for the family's various devices. Anyone happen to do such a thing,or is that claim up for the taking. :P

@BoraxMan25 1st I would not call it meaningless example. It works the same way.

2nd, not all peoples really need multi-core PCs for highend gaming. They basically do office work and with cloud it rally could be possible to do office work at home. And that would save resources and energy a lot.

3rd, with cloud you actually can play highend games on tablet computers. So you can play your favorite DirectX 11 game, while you are waiting for plane etc.

It is not that bad at all.

[BoraxMan25]

Yet the move now is for people to install solar power panels, and generate their own electricity again. computing has nothing to do with power plants, the example is meaningless. The computing power each individual has now is equivalent to a supercomputer of a decade or two ago. There simply is no need for the cloud, other than to generate extra profits from IT business' which cannot innovate and provide the next fad for IT. BTW, cloud computing seems nothing more than transferring data.

Societies dependance on the electric, internet, telecom grids could sometime bite it in the butt big time. A wholesale move to cloud computing could really acerbate the effects of any failures. Unless some of the savings are invested contingency plans, but that isn't going to happen.

[joungerbros]

While I have seen some specialized hobbyist applications that use something like cloud computing, I really don't see it becoming used that much by the average personal computer user. Not beyond the storage of often used data file that one desires to access from any internet connection available to them anyway. For data to be used from the home monthly charge quickly outweigh the cost of external HDD or a lot of USB flash memory from WalMart..
