“cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effor t or service provider interaction.” – NIST

NIST Service/Deployment models● Service Models:
● IaaS (e.g EC2, rackspace)● PaaS (e.g GAE, Azure)● SaaS (e.g Gapps)
● Deployment model:● Private cloud● Public cloud● Hybrid cloud (Private than can use Public)
OpenSourceDay 2012
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
