Cloud computing is currently at under 10% of the IT market. Predictions by Goldman Sachs indicate growing to about 50% by 2015 and higher by 2020 to as much as 80%.

2. What is more important control or trust?
3. Is it better to have operational expenses vs capital expenses?
4. Do you need a scalable system or is fixed going to work?

2. Access – anytime, anywhere
3. Scalability
4. Management
