Agenda

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.

Companies inside the Cloud

Reference Stack

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)

Infrastructure as a Service (Iaas)

Infrastructure as a Service (Iaas)

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

Platform as a Service (PaaS)

Platform as a Service (PaaS)

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)

Software as a Service (SaaS)

Software as a Service (SaaS)

Examples of BAS are:

Examples of CAS are:

Google docsMicrosoft Office Live

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

Cloud Federation

Resource migration

Combination of complementary

resources

Resource redundancy
