Description

As Grids and service-oriented architectures evolved to a common infrastructure for providing and consuming services in research and commercial environments, mechanisms are needed to agree on the objectives and the quality of such service provision. There is a clear trend to use electronic contracts between service consumers and one or more service providers, in order to achieve the necessary reliability and commitment on both sides. Service Level Agreements (SLAs) are the means to model and manage such contracts in a unified way.

This workshop will provide a forum to present current research and up-to-date solutions from research and business communities. The workshop considers Grids but also generic models for SLA management. That is, market-economic strategies, negotation, or monitoring are also of interest.

Topics of Interest

Topics of interest for the Usage of Service Level Agreement in Grids workshop include but are not limited to:

• Areas benefiting from SLAs
• Languages to express SLAs (e.g. SLOs, BLOs, QoS, Guarantees, Penalties)
• Protocols to conclude and negotiate SLAs
• Technologies for management and observation of SLAs
• Static vs. Dynamic SLAs
• Business models & Grid economy
• Negotiation and agreement protocols and strategies
• Validation techniques for SLA parameters
• Comparison and matchmaking of SLA and policy descriptions
• Managing user expectations via SLAs
• Multi-party SLAs and SLA chaining
• SLA-based resource discovery, co-scheduling and resource reservation
• Registry Services and repositories for SLA
• SLA-based trust management including VOs
• Monitoring, provisioning, enforcement of SLAs

Proceedings

It is planned to publish accepted papers in the CoreGRID Springer Series. More information regarding paper format and style will be provided as soon as possible.
 

Paper Submissions

Authors are invited to submit manuscripts reporting original unpublished research and recent developments on the topics of interest. Submitted papers should be formatted according to the CoreGRID Springer style format and should not exceed 10 pages including figures and references. Papers should be submitted electronically in PDF format by sending it as an e-mail attachment to sla-workshop2008@scai.fraunhofer.de.
