Summary
When considering integration of business into the grid infrastructure, users (physical persons, or institutions) can be divided into two groups, according to the role that they play: (i) owners (service providers) who make their resources accessible, and (ii) clients who search for resources to commission execution of a job. Note that these roles are interchangeable, as providers of one type of services may become consumers of another. Separately, it should be pointed out that "business" computations are usually conducted in a predefined order, and within a fixed time frame (contrary to volunteer computing projects, e.g. the folding@home, where neither of these two factors plays an important role). In order to assure availability of resources, and timeliness of job execution, it is necessary to formalize the contract in the form of a service level agreement (SLA), followed by job monitoring, as well as assessing the quality of service. Therefore, grid systems that aspire to provide business solutions should also consider the SLA management as part of their functionality. Here, the SLA is defined as a contract between a user of a service and a service provider, specifying the scope of the service and co-operation conditions offered during the period of contract validity, to ensure the quality of service (QoS). The SLA can be considered as a means to provide more flexibility, scalability and optimizing resource utilization, and, consequently, increase the reliability of the grid.

In our Agents in Grid (AiG) project, software agents are to provide a meta-level grid middleware, in which (a) agents work in teams (managed by LMaster agents), (b) all meta-information is ontologically demarcated and semantically processed, and (c) an economic model is to be based on autonomic SLA negotiations, and QoS monitoring.

The aim of this chapter is to present an overview of issues concerning autonomous (possibly agent-based) \textit{Service Level Agreement} negotiations. To achieve this goal, first five European research projects are discussed that represent different approaches to the problem of integration of business and grid architectures, as well as various methods of establishing the SLA between grid users. Second, the experience gained from these projects is used as a foundation of conceptualization of the SLA negotiations in the AiG project.
