• A distributed computing infrastructure to provide the production and analysis environments for the LHC experiments
• Managed and operated by a worldwide collaboration between the experiments and the participating computer centres
• The resources are distributed – for funding and sociological reasons
• Our task was to make use of the resources available to us – no matter where they are located
• Secure access via X509 certificates issued by network of national authorities - International Grid Trust Federation (IGTF)

WLCG – what and why?
Tier-0 (CERN):• Data recording• Initial data reconstruction• Data distribution
Tier-1 (11 centres):• Permanent storage• Re-processing• Analysis
Tier-2 (~130 centres):• Simulation• End-user analysis

• WLCG has been leveraged on both sides of the Atlantic, to benefit the wider scientific community
– Europe (EC FP7):
• Enabling Grids for E-sciencE (EGEE) 2004-2010
• European Grid Infrastructure (EGI) 2010--
– USA (NSF):
• Open Science Grid (OSG) 2006-2012 (+ extension?)
• Many scientific applications

How to evolve WLCG?
A distributed computing infrastructure to provide the production and analysis environments for the LHC experiments
• Collaboration - The resources are distributed and provided “in-kind”
• Service - Managed and operated by a worldwide collaboration between the experiments and the participating computer centres
• Implementation - Today general grid technology with high-energy physics specific higher-level services
Evolve the Implementation while preserving the collaboration & service

CERN openlab in a nutshell
• A science – industry partnership to drive R&D and innovation with over a decade of success
• Evaluate state-of-the-art technologies in a challenging environment and improve them
• Test in a research environment today what will be used in many business sectors tomorrow
• Train next generation of engineers/employees
• Disseminate results and outreach to new audiences

Looking to the future• Massive adoption of virtualisation techniques by e-Science centres
– To reduce operation costs & simplify deployment of applications using images• Federated identity system
– network of trust across public & private organisationssee paper https://cdsweb.cern.ch/record/1442597
• “Grid extensions” added to clouds (first private then public)– Federated identity system, support for virtual organisations, etc. – Use of commercial cloud services as extensions to in-house resources
• Blurring of the borders between elements of e-infrastructure (networking, grid & supercomputing)
– Because the users & funding agencies demand it• Emergence of a data e-infrastructure
– Such systems are helping to create the Digital European research Area by ensuring secure access to and preservation of research data
