4 The Evolution of the Compute Grid R E S E R V O I R today s commercial clouds have not been open and general purpose, but instead been mostly proprietary and specialized for the specific internal uses (e.g., large-scale data analysis) of the companies that developed them. The idea that we might want to enable interoperability between providers (as in the electric power grid) has not yet surfaced w w.smcplus.com/applications.asp?id=32 will move towards a mix of microproduction The Dulles, OR and large utilities, with increasing numbers of small-scale producers co-existing with largescale regional producers, and load being distributed among them w w.informationw eek.com/galleries/show Image.jhtml?galleryID=62&imageID=13 w w.by-star.net/techspeak/datacenter/ dynamically Make your own infrastructure Not the company s main business but a considerable competitive advantage The utility industry Efficient distribution MeteringThere s Grid in then thar Clouds Federation - Ian Foster of providers Limited reach The diversity factor Reproducible (yet costly) Economies of scale 4 7th HLRS Scalable Global File System Workshop

5 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 IT 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 5 7th HLRS Scalable Global File System Workshop

6 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 business service management The Service Oriented Infrastructure (SOI) equation: Virtualization -Aware Grid e.g., VM usage/size as the unit for metering and billing + + Grid-Aware Virtualization e.g., live migration across administrative domains BSM e.g., policy-based management of service-level agreement = SOI 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 6 7th HLRS Scalable Global File System Workshop

34 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 and extend it 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) SLA monitoring across administrative domains settings 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. 34 7th HLRS Scalable Global File System Workshop
