Exploring opportunities in the OGSA service model– realising Utility Computing Jeffrin J. Von Reich Chief architect Hewlett Packard Software Global Unit

page 2 The World of Utility Computing services supply demand applications resources

page 3 – Pay per unit of usage ( computing, storage,apps, services) – SLA defined for consumption – Resources are on demand from a shared pool – Less expensive than purchasing dedicated resources – Highly automated, policy driven administration – Potential distribution of resources across geographies/firewalls – Interoperability of heterogenous environments – Supports incremental building block approach of infrastructure/apps/services What makes an Utility Computing Environment

page 4 Utility Computing is one of the business/operating IT models. The construction of UC stack is constrained mainly by – the functional richness of the underlying interfaces (servers, storage, networks,,,) – the standardization of an architecture that allows interoperability Grid and UC – whats the connection Grid is a technology that seems suitable to deliver UC Therefore the standards bodies that work on grid and UC could have the same taxonomy and high level architecture ( OGSA )

page 5 Web Services Messaging, Security, Etc. Domain-Specific Services WS-Resource Framework OGSA-WG taxonomy OGSA services Infrastructure.

page 6 Infrastructure Services OGSA services + Mgmt Building blocks Manageability and SOA basis – WSRF, WSDM.. UC and grid – a possible common taxonomy ? Exchange Service Servers - e.g server pool Storage BPEL processes Network Business Services Application Services Global management ( Asset mgmt, Usage and metering ) Integration, composition and communication between management blocks - model based. Causes supply and demand automation Server pool managerExchange manager Mail manager Utility delivery automation Utility delivery
