What is inside a cloud? An architectural map of the cloud Landscape • Presented by: • Omer Iltaf • 1st Semester • BCM
Agenda • What is inside a CLOUD • Reference Stack • Cloud computing Services. • Eco system • Cloud Federation • Conclusion
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)
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
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) Examples of BAS are: Examples of CAS are: Google docs Microsoft Office Live
Human as a Service (HuaaS) Top most layer in the cloud computing Brings creativity in the cloud computing paradigm Use 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
