This document discusses cloud computing and its advantages. It defines cloud computing's five essential characteristics as on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It outlines three service models (software as a service, platform as a service, infrastructure as a service) and four deployment models (private cloud, community cloud, public cloud, hybrid cloud). The document argues that cloud computing provides advantages like lower upfront costs, scalability, and flexibility, but also discusses risks and challenges that need to be addressed like security, compliance, and vendor lock-in.

2. Whostartedallthis?“What's interesting [now] is that there is an emergent new model, and you all are here because you are part of that new model. I don't think people have really understood how big this opportunity really is. 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.”Mr. Eric Schmidt, Chairman & CEO GoogleSearch Engine Strategies Conference,9th of August 2006http://www.google.com/press/podium/ses2006.html 5 August 2011 – Virtual Seminar and Tradeshow
