What is inside a cloud? An architectural map of the cloud Landscape Presented by: Omer Iltaf 1 st Semester BCM
What is inside a CLOUD Reference Stack Cloud computing Services. Eco system Cloud Federation Conclusion 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)
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)
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
