Cloud Computing
Five essential characteristics:
- On-demand self-service. provision computing capabilities
as needed automatically.
- Broad network access. available over the network and
accessed through standard mechanisms.
- Resource pooling. computing resources are pooled with
location independence
- Rapid elasticity. Capabilities can be rapidly and
elastically provisioned.
- Measured Service. automatically control and optimize
resource

Cloud Computing
Three service models
- Cloud Software as a Service (SaaS)
- Cloud Platform as a Service (PaaS)
- Cloud Infrastructure as a Service (IaaS)
- Data as a Service (DaaS)

U.S. 2010 budget
“The Federal technology environment requires a fundamental re-examination of investments in technology infrastructure… Pilot projects will be implemented to
- ffer an opportunity to utilize more fully and broadly
departmental and Agency architectures to identify enterprise-wide common services and solutions, with a new emphasis on cloud-computing.”

Spatial Cloud Computing
Spatial Cloud Computing refers to the computing paradigm that is driven by geospatial sciences, and
- ptimized by spatiotemporal principles for enabling
geospatial and other science discoveries within distributed computing environment.
