While much research is dedicated to the technical aspects of cloud computing, many authors neglect the IT provisioning, i.e., the business perspective of cloud computing. In this regard cloud computing has the potential to revolutionize the mode of computing resource and application deployment, breaking up traditional value chains and making room for new business models. Many providers like Amazon, Google, IBM, Microsoft, Salesforce, or Sun positioned themselves as platform and infrastructure providers in the cloud computing market. Beside them there emerge more and more providers, who build their own applications or consulting services upon infrastructure services offered by other market players.

6. Eg Measured Service: Utility Computing
• “Computing may someday be organized as a public
utility” – John McCarthy, MIT,1961
• “Packaging of computing resources, such as
computation and storage, as a metered service
similar to a traditional public utility, such as
electricity”
– A break in the clouds: towards a cloud
definition, ACM SIGCOMM, 2009
• Hugh computational and storage capabilities
available from utilities
• Metered billing “Pay-As-You-Go”

3 Cloud Service Models
• Cloud Software as a Service (SaaS)
– Use provider’s applications over a network
• Cloud Platform as a Service (PaaS)
– Deploy customer-created applications to a cloud
• Cloud Infrastructure as a Service (IaaS)
– Rent processing, storage, network capacity, and other
fundamental computing resources
• To be considered “cloud” they must be deployed on
top of cloud infrastructure that has the key
characteristics
