5 5 Computer Utilities Vision: Implications of the Internet 1969 Leonard Kleinrock, ARPANET project As of now, computer networks are still in their infancy, but as they grow up and become sophisticated, we will probably see the spread of Computer Utilities, which, like present electric and telephone utilities, will service individual homes and offices across the country. During the last 40 years, several advances have taken place in both computing and communications areas that are turning the vision of Computer Utilities in to a reality.

10 Defining Clouds: There are many views for what is cloud computing? Over 20 definitions: Renting remote storage backup Renting remote server hosting Web server Renting remote more servers to manage large workload Buyya s Scientific definition of Cloud Computing 10 Cloud is a market-oriented distributed computing system consisting of a collection of inter-connected and virtualised computers that are dynamically provisioned and presented as one or more unified computing resources based on servicelevel agreements (SLAs) established through negotiation between the service provider and consumers. SLA = {negotiated and agreed QoS parameters + rewards + penalties for violation of agreement...}

11 Subscription-Oriented Cloud Services: X{compute, apps, data,..} as a Service (..aas) Public Clouds Applications Cloud Manager Development and Runtime Platform Storage Compute Clients Private Cloud Other Cloud Services Govt. Cloud Services 11

12 Cloud Services Infrastructure as a Service (IaaS) CPU, Storage: Amazon.com, Nirvanix, GoGrid. Platform as a Service (PaaS) Google App Engine, Microsoft Azure, Aneka..
