6 Introduction One VRE is a time-defined distributed environment to satisfy concrete collaboration needs of distributed user communities VRE users are organized in Virtual Organizations VRE resources are organized in Infrastructures Creating a VRE 10 October 2008, Dubna (Russia)

7 Infrastructure Hardware: Storage, Computing Services & Applications: gCube External Collections & Auxiliary Resources: Data, Content, Metadata Schemas, Mappings, Transformation programs Creating a VRE 10 October 2008, Dubna (Russia) A D4Science infrastructure is composed by:

11 gCube gCube is the system developed by D4Science to create and maintain Virtual Research Environments. gCube is composed by:  Infrastructure Enabling Services  Information Retrieval Services  Information Organization Services  Presentation Services gCube components can be: Services, Libraries, and Portlets Creating a VRE 10 October 2008, Dubna (Russia)

12 gCore gCore is a framework developed by D4Science to reduce the complexity of designing and implementing gCube services. gCore is composed by:  Framework: An application framework to consolidate and develop existing/new gCube services  Container: A self-contained software container distributed to facilitate the deployment of gCube services. Based on Java WS-Core (GT4). Creating a VRE 10 October 2008, Dubna (Russia)

13 gHN The minimum environment for any gCube node of the infrastructure is the gCube Hosting Node (gHN) The gHN is composed by:  gCore Container  gCore Framework  gCube Infrastructure Enabling Services (partial) Creating a VRE 10 October 2008, Dubna (Russia)

14 gHN The gCube Hosting Node main functionality is:  Is the runtime container of gCube services  Provides access to local hardware resources,  Storage systems, instruments, CPU cycles  Grants lifetime management  Mediates service2service interactions  route requests to target service  enforce security and scope policies Creating a VRE 10 October 2008, Dubna (Russia)

15 gLite Computational intensive tasks are executed in EGEE nodes running the gLite middleware. EGEE is one the largest grid infrastructure worldwide. It is composed by more than 260 sites (85k CPUs) Several gCube services were designed to interface with the gLite middleware. These interfaces give access to the EGEE infrastructure and consequently increase significantly the computing capabilities of any gCube-based infrastructure.

19 Interfaces From the “system administrator” perspective the creation of one gCube-based infrastructure, VO, VRE is done exploiting two main types of interfaces Command Line Interface (CLI)  Used for the installation of gHNs Portal  gCube portal is based on portlets technology (JSR168)  gCube portal runs on GridSphere  Used for the creation and management of VOs and VREs Creating a VRE 10 October 2008, Dubna (Russia)

27 How to Start How can a new user community have it’s own VO/VREs ? 1.By creating a new infrastructure  Different communities can run their own infrastructure  The new community provides all resources 2.By joining an existing infrastructure  D4Science runs a production infrastructure for its two user communities (Earth Monitoring and Fisheries Management)  The new community provides part of the resources Creating a VRE 10 October 2008, Dubna (Russia)

30 Conclusions A VRE brings together different types of resources through a well defined cost-effective process The creation of a VRE is a simple and easy:  A new VO can join one infrastructure in less then 1 day  A new VRE can be deployed in less then 2 hours  Many automatic deployment & configuration operations managed via the gCube Portal Creating a VRE 10 October 2008, Dubna (Russia)
