1. Introduction to Cloud Computing 1
2. Session Agenda 2 Agenda ¨  Cloud Computing ¨  Definition ¨  Service Models ¨  Classification ¨  Homework Assignment ¨  Discussion on the topic
3. Cloud Computing 3 Definition ¨  Model to enable on demand access to shared pool of computing resources ¤  On demand self-service ¤  Resource pooling ¤  Rapid elasticity ¤  Measured service ¤  Broad network access
4. Cloud Computing 4 Industry trend driven by: •  Virtualization •  Grid computing •  Self service •  Policy based scaling •  Pay per use Key Service Models: •  Software as a Service (SaaS) •  Platform as a Service (PaaS) •  Infrastructure as a Service (IaaS)
5. Software as a Service 5 SaaS ¨  Software delivered as a service ¨  Delivered to the end users ¨  Over the internet ¤  via web browser or ¤  via web apps
6. Platform as a Service 6 PaaS ¨  Application development platform ¨  Delivered to developers as a service ¨  Over the internet ¤  Used via programming/dev tools
7. Infrastructure as a Service 7 IaaS ¨  Computing resources (servers, storage, networking hardware, and related software) delivered as a service ¨  Delivered to the application developers ¨  Over the internet ¤  Used via resource management tools
8. Layers of Service 8 Infrastructure served Platform served Application served
9. Cloud Classification 9 Types ¨  Public Cloud ¨  Private Cloud ¨  Hybrid Cloud
10. Public Cloud 10 Public ¨  Resources available to the public ¨  Offered by a service provider ¨  Lower upfront costs ¨  Easier to manage ¨  Can be difficult to integrate with other assets ¨  Offer less control This is like renting a taxi
11. Private Cloud 11 Private ¨  Resources available to the owners ¨  Managed by owner or proxy ¨  Lower total costs over the long run ¨  Greater control over ¤  Security ¤  Quality of service ¤  Compliance ¨  Easier integration with existing assets This is like owning a car
12. Hybrid Cloud 12 Hybrid ¨  Single application works across both public and private clouds ¨  Bursts out to public cloud for work load peaks ¨  Requires standards based interoperability ¨  Portability across clouds ¨  Optimal solution: Finely aligned to business needs at moderate costs ¨  Balance of cost/benefits ¨  Retain control over ¤  Security ¤  Quality of service ¤  Compliance Own your car + rent taxi(s) for guests that need service
