Cloud Computing © 2008 IBM Corporation 1 Cloud Computing From 30,000 Feet Fast growth of connected mobile devices Skyrocketing costs of power, space, maintenance, etc. Advances in multi-core computer architecture Explosion of data intensive applications on the Internet The Cloud data center “It starts with the premise that the data services and architecture should be on servers. We call it cloud computing – they should be in a ‘cloud’ somewhere. And that if you have the right kind of browser or the right kind of access, it doesn’t matter whether you have a PC or a Mac or a mobile phone or a BlackBerry or what have you – or new devices still to be developed – you can get access to the cloud…” – Dr. Eric Schmidt, Google CEO, August 2006
