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.
