gSLMService Delivery & Service Level Management
in Grid Infrastructures
General presentation
Background – grid services
• The evolution of grids– System for connecting and federating resources
at multiple geographical locations
– Based on sharing computers in academic organisations across Europe
– Used by a wide range of European researchers
– Based on complex net of relationships between the resource owners, grid operators and end users
– Agreements are informal
The need for grid SLM
• Before– The informal approach to service level management stopped the
need for formal legal agreements slowing grid development
• Now– Grids getting into more mission critical areas– Increasing commercial interest in grids and other e-
infrastructures (like clouds)– Lack of formal SLM has become a barrier to grid development
and uptake
• The service delivery problem in e-infrastructures
Traditional vs. e-Infrastructures
SLAs and the Service Delivery Problem in e-Infrastructures
• The role of SLAs in traditional service provider scenarios:
– SLAs align the capabilities of an IT provider with the customer/business requirements.
– SLAs build a contractual framework for mutual obligations and responsibilities.
– SLAs clearly define the services to be provided, where applicable by referencing a catalog of service specifications.
• The “Service Delivery Problem” in e-Infrastructures:• Often no single central authority with
control over service delivery, service levels and management processes
• Often no hierarchic service chain with clear distribution of responsibilities
• Service commitments and dedication of resources to the grid on a voluntary basis
• No sophisticated formal agreements on service functionality and quality
The gSLM project
• The gSLM project aims to help solve the e-Infrastructure delivery problem
• Leverage knowledge of IT service management (ITSM) community to do this
• Bring together grid and ITSM experts and formulate new approaches to SLM in grid
• Experts from both communities within the project– Grid operators, developers, policy and communication experts– Academics and accredited experts in ITSM approaches to
service level management

Minimum requirements ISO/IEC 20000 provides a roadmap / checklist of things to be done
Key processes and information artifacts ITIL defines key processes and provides an overview of best practices and supporting concepts.
Templates and Job Aids MOF helps to make processes operational.
Process and information models eTOM and SID help defining process models and understanding management information
gSLM outputs
• Workshops– Two dedicated workshops run by gSLM on service
level management in grids
• Events– Attendance at events from both ITSM and grid
communities to disseminate results and invite input
• Reports– White papers on need for SLM in Grids– Strategic roadmap on grid SLM
