Foundations of IBM Cloud Computing Architecture V4

Fixed pricing:lowering fixed/variable costs and offering known pricing schemes. Planning: driving better data center planning for building more private data centers. Virtualization:abstracting physical resources away from their underlying hardware resources in order to improve IT control. Pervasiveness:improving customer experience by enabling services to be accessed fromanywhere, anytime, and on any device. Virtualization:providing more efficient utilization of IT resources and reducing hardware cost through resource consolidations and economies-of-scale.

It can be a consumer of multiple cloud services for their own use. ✘ It consumes other cloud services by leveraging and enhancing functionality exposed by the cloud service provider. ✘ It is the individual, organization, or system which consumes service instances deliveredby a particular cloud service. ✘ It is responsible for the design, testing, implementation, and maintenance of management artifacts specific to a cloud service. ✔

Dynamic, flexible chargeback model. Faster access to data stored on the cloud. Secure access to data stored on the cloud. Reduction in total cost of ownership and better return on investment. Facilitates applying policies across many independent filers in an enterprise.
