Motivation • The amount of resources and the variety of applications is steadily increasing, manpower unfortunately is not • It is becoming almost mandatory to consolidate such resources to achieve scalability and economies-of-scale – Separate application management from infrastructure management – Our Data Centers need to become providers of computing and storage resources, not (only) of high level services • The Cloud approach (Iaa. S) might help to better provision resources to the different scientific computing applications – Grid Sites, small or medium computing farms, single users, … – Admit dynamic resource relocation to increase CPU power for a Grid and reduce some other that are not using resources or having less priority • Several cloud computing projects are starting at national and European level – From definition of best practices and reference configurations to deployment of large-scale distributed infrastructures – A local working cloud infrastructure will also allow to take immediately part in such activities
Cloud Computing • On-demand self-service. – A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. • Broad network access. – Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client. • Resource pooling. – Computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. • Rapid elasticity. – Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. • Measured service. – Cloud systems automatically control and optimize resource use by leveraging a metering capability at a level of abstraction appropriate to the type of service.
