Shared pool of configurable computing resources
On-demand network access
Provisioned by the Service Provider
Cloud computing is an information
technology paradigm that enables
ubiquitous access to shared pools of
configurable system resources and higher-
level services that can be rapidly
provisioned with minimal management
effort, often over the Internet.

Adopted from: Effectively and Securely Using the Cloud Computing Paradigm by peter Mell, Tim
Grance
◦ (^) Remotely hosted : Services or data are hosted
on remote infrastructure.
◦ Ubiquitous : Services or data are available from
anywhere.
◦ (^) Commodified : The result is a utility computing
model similar to traditional that of traditional
utilities, like gas and electricity - you pay for
what you would want!
Pay per use: Compute resources are measured at a granular
level, enabling users to pay only for the resources and
workloads they use.
Workload resilience: Cloud service providers often
implement redundant resources to ensure resilient storage
and to keep users' important workloads running -- often
across multiple global regions.
Migration flexibility: Organizations can move certain
workloads to or from the cloud -- or to different cloud
platforms -- as desired or automatically for better cost
savings or to use new services as they emerge.
