Cloud Computing is the next stage in the Internet's evolution, providing the means
through which everything — from computing power to computing
infrastructure, applications, business processes to personal collaboration — can be delivered to you as a service wherever
and whenever you need.

Infrastructure as a Service (Iaas)
Iaas is the lowest level of service being provisioned by the cloud.
Iaas enables abstracted view hardware such as servers, storage and network devices.
The items offered in the resource set are:
Physical Resource Set (PRS) Virtual Resource Set (VRS)

Examples of the PRS are:
Examples of VRS are

Platform as a Service (PaaS)
PaaS is the middle level of service being provisioned by the cloud.
Programming Environment
Execution Environment

Software as a Service (SaaS)
Saas is the upper most level of service being provisioned by the cloud.
Saas enable to directly built software's on PaaS or only use IaaS plateform
SaaS can be distinguished in two categories:
Basic Application Service( BAS) Composite Application (CAS)

Examples of BAS are:
Examples of CAS are:

Human as a Service (HuaaS)
Top most layer in the cloud computing
Brings creativity in the cloud computing paradigmUse of human intelligence
Examples of HuaaS are:Crowdsourcing

Supporting Management & Service
Some services in the cloud need to have access to all layers in the stack to present a coordinated view to its users i.e.
For debugging storage
Monitoring
Billing purposes
