Last week the first sentence of an article in the InformationWeek periodical specifically targeted at IT employees of the U.S. Government read as follows:
‘The General Services Administration has issued a Request For Quotation for cloud storage, Web hosting, and virtual machine services.’
You can read the whole post here.
The next quote i pointed here, because from my point of view this is one of the best “introductions” and “term explanation” about the cloud computing topic i read the last weeks and months.

Cloud computing is a model for enabling 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 effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three delivery models, and four deployment models.
- Essential characteristics:
- On-demand self-service
- Ubiquitous network access
- Location independent resource pooling
- Rapid elasticity
- Measured service
- Delivery models:
- Cloud Software as a Service (SaaS) – Use provider’s applications over a network
- Cloud Platform as a Service (PaaS) – Deploy customer-created applications to a cloud
- Cloud Infrastructure as a Service (IaaS) – Rent processing, storage, network capacity, and other fundamental computing resources
- Deployment models:
- Private cloud – enterprise owned or leased
- Community cloud – shared infrastructure for specific community
- Public cloud – Sold to the public, mega-scale infrastructure
- Hybrid cloud – Composition of two or more clouds
