NIST Service/Deployment models● Elasticity

● Expands and Shrinks as needed● E.g Elastic Load Balancing, Elastic Map Reduce

● Measured Service● Utility Pricing. You pay for what you use● E.g $0.08 for one hour of small instance

● On-demand● You get it when you ask for it● E.g One api call and you get your machine, no queue
