WHAT IS CLOUD COMPUTING?!
"Clouds are hardware-based services, offering
compute, network and storage capacity where:
1.Hardware management is highly abstracted from the buyer
2.Buyers incur infrastructure costs as variable OPEX
3.Infrastructure capacity is highly elastic (up or down)"
What do the NIST Guys tell us:
• Broad network access
• Resource pooling On demand self-service
• Rapid elasticity
• Measured service
• On demand self-service

LETS TAKE A CLOSER LOOK
On demand self-service:
"A consumer can unilaterally provision computing
capabilities such as server time and network storage,
as needed automatically without requiring
