2. Virtualized Service Platform 22.9.08 Brussels The RESERVOIR Vision The Next Generation Infrastructure for Service Delivery –Provide revolutionary foundation for a new European infrastructure where resources and services can be transparently and dynamically managed, provisioned and relocated like utilities – virtually “without borders” –No single facility/provider can create a seemingly infinite infrastructure capable of serving massive amounts of users at all times, from all locations Federation of clouds Leverage the diversity factor to achieve economies of scale Leverage locality –Analogies exists in areas outside services: Electrical power delivery: capacity can be shifted to guarantee supply and lower costs Roaming cellular communications: Talk wherever you are Impact –Enable utility-like deployment of services, relieving the service consumer from awareness of the IT attributes while assuring QoS and security guarantees –Aim to create the basis for future service products

3. Virtualized Service Platform 22.9.08 Brussels Approach Focus on technologies that enable to build cooperating computing clouds –Connect computing clouds to create an even bigger cloud Integration of virtualization technologies with grid computing driven by new techniques for service management   The Service Oriented Infrastructure (SOI) equation: Building on this equation we will architect and implement a platform for supporting complex services, which Enables dynamic deployment of complex multi-tier services across heterogeneous administration domains Uses virtualization of servers, storage and network to allow migration without borders Supports service definition, SLA management, accounting and billing Grid-aware Virtualization Service-oriented capacity provisioning across sites Grid-aware Virtualization Service-oriented capacity provisioning across sites Virtualization- aware Grid Optimal placement of VMs on a federated cloud Virtualization- aware Grid Optimal placement of VMs on a federated cloud Business & Service Management Policy-based management of service-level agreements Business & Service Management Policy-based management of service-level agreements SOI

8. Virtualized Service Platform 22.9.08 Brussels A3: VEE Management VEE Provisioning and Supervision (UCM) –Image management –Monitoring Allocation Policy Management (Datamat) –Policy based placement and migration Federation of Management Domains (UCM) –Built atop WSRF interfaces to access remote VEE Supervisors Push new and leverage existing OGF/DMTF/OASIS standards –Interoperability between administrative domains and scheduling heuristics on federated and utility architectures.

9. Virtualized Service Platform 22.9.08 Brussels A4: Service Management Service Definition (UCL) –Design a new service description language that will allow the description of service interfaces, service lifecycle, interface bindings to implementations, service deployment, SLA requirements for a service, rules for VEEs (re)configuration and (re)organisation and service components distribution and configuration –Revisit the service lifecycle definition to accommodate the influence of virtualisation –Extend tools available for service design (for example the Eclipse Web Tools Platform) –Standardize the service description language Service Management (TID, UCL) –SLA monitoring across administrative domains and service-oriented architectures. –Integrate monitoring with resource allocation and scheduling and take explicit account of the potentially synchronous nature of service invocations. –Automatic deployment of services based on complex service definition Accounting, Billing and Payment (TID) –Accounting and billing arrangements for outsourced services are based on raw machine resource consumption (CPU-time, storage capacity etc) –RESERVOIR will pursue the definition of a framework that allows accounting and billing in terms of the services that were completed, taking into consideration the quality of service that was provided.

10. Virtualized Service Platform 22.9.08 Brussels A5: Experimentation and Validation Testbed (UniMe) –Create the necessary environment for testing and validation –Support the execution of use cases Scenario 1: eGov application (Thales) –Automatic adjustment of resources and domains cooperation. Scenario 2: SAP business application (SAP) –Business application oriented use cases and the opportunities to execute them on a flexible infrastructure. Scenario 3: Utility computing (Sun) –Deploy arbitrary operating system and application stacks on remote resources. Provide secure and seamless access to them. Adjust resource allocation on-demand without the end user noticing disruption of service Scenario 4: Telco application (TID) –Hosting web sites that deals with massive access (e.g., the Olympics games) –High degree of personalization and support for mashups
