RESERVOIR at EGEE’09


RESERVOIR is participating at EGEE’09 which is taking place in Barcelona this week. As well as an exhibition stand at the event, a session dedicated to RESERVOIR and EGEE collaboration has outlined how the two projects are working together to explore how the institutes providing computing resources to EGEE could benefit from adopting private and hybrid cloud models to provide resources.

Workshop summary and presentations available for download

EGEE’09, 21 September 2009, Barcelona, Spain

This session, chaired by Ignacio Llorente, RESERVOIR & Universidad Complutense de Madrid (UCM), and Steven Newhouse, EGEE. Llorente kicked off the sesion by presenting the progress of the three main technical activities in the collaboration between RESERVOIR and EGEE:

  1. Evaluation of scalability and reliability of a Private Cloud Deployment for dynamic provisioning of EGEE virtual Worker Nodes
  2. Evaluation of a Hybrid Cloud Model with the combination of Private Infrastructure with Cloud Resources to expand the computing capacity of a EGEE site
  3. Evaluation of a Public Cloud Model for the operation of a full virtualized EGEE site

Ruben S. Montero, UCM gave the second presentation where he discussed the capabilities provided by the OpenNebula open-source cloud toolkit and RESERVOIR technology for virtual machine management, to build cloud infrastructures.

Ulrich Schwickerath, CERN, then gave a presentation about the work CERN is doing in the context of this collaboration to complement batch services with virtualization technology. Existing grid standards, like JSDL, and minor modifications of the CREAM Computing Element will be used to enable the on-demand provisioning of Virtual Machines tailored to the jobs needs. This has major advantages for example, in the description of the batch job, requirements can be set to identify the proper Virtual Machine, with all needed software dependencies.

Schwikerath then evaluated the virtual machine orchestrater (VMO), a commercial solution by Platform computing, and the free software solution OpenNebula. For VMO, the vendor provided a first implementation of an algorithm for selecting the image to be deployed, which is driven by user requirements of pending batch jobs. For OpenNebula, an external mechanism is being developed to perform this task in the context of this collaboration effort.

An additional advantage of RESERVOIR is its implementation of the EC2 interface, which is being evaluated by CERN.
