5. 15 Typical Customer Requests  How can we provide flexible compute resources quickly to promote rapid prototyping?  How do we deploy applications that scale up to meet increasing demands over time?  How do we manage 100,000’s of machines with minimal human intervention?  How can we make the most efficient use of all the compute resources in a data center?

6. 16 What do users want?  Users do not care about how the works are done – Instead, they only concern about what they can get  Users do not care about what the provider actually did – Instead, they only concern about their quality of service  Users do not want to own the physical infrastructure – Instead, they only want to pay as many as they used  What does user really care ? – They only care about their “Services” – And how to access them

8. 20 Network-based subscriptions to applications Anytime, anywhere access to IT resources delivered dynamically as a service. Utility Computing Offering computing resources as a metered service Evolution Towards Unparalleled Scalability A “cloud” is an IT service delivered to users that has:  A user interface that makes the infrastructure transparent to the user  Reduced incremental management costs when additional IT resources are added  Services oriented management architecture  Massive Scalability Cloud Computing Softwareas a Service Grid Computing Solving large problems with parallel computing

9. 21 Monitor & Manage Services & Resources Cloud Administrator Datacenter Infrastructure Once again: What is Cloud Computing? A user experience and a business model  Cloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model. An infrastructure management and services delivery methodology  Cloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling.

10. 29 Cloud Service Models Software As A Service (SaaS) Platform As A Service (PaaS) Infrastructure As A Service (IaaS)

11. 33 Infrastructure as a Service (IaaS) NIST Definition: The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. Examples :  Amazon EC2  Rackspace Open Cloud  IBM Smart Cloud Enterprise  III Cake …

12. 34 Platform as a Service (PaaS) NIST Definition: The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. Examples :  Microsoft Windows Azure  Google App Engine  Hadoop  …

13. 35 Software as a Service (SaaS) NIST Definition: The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser. Examples :  Google Apps  SalesForce.com  EyeOS  …

15. 49 Enterprise Adoption of Cloud Computing  Enterprise adoption of cloud computing often requires a significant transformation of existing information technology (IT) systems and processes.  To justify such a change, a viable business case must be made based on the economics of transformation such as – cost of transformation, – return on investment (ROI), and – payback period analysis.  The expected return from investing in the planned transformation and the estimated time to recoup the investments made determine whether such a transformation is to be undertaken.
