Service environments can integrate grid services offering computational services for other participants of a service community. Grid broker services abstract out grid service selection, job submission and management functionalities. Crucial to grid brokers and grid services is their stateful nature that complicates their design (WSRF). [CD-JRA-2.3.4] [CD-JRA-2.3.2] | Grid Brokering schedules user tasks to highly dynamic resources in heterogeneous and distributed environments. This task needs unified monitoring techniques and a high level of adaptation to cope with inevitable resource failures. [Krauter et. al, 2002] [CD-JRA-2.3.4] [CD-JRA-2.3.2] | Grid Brokering may support quality assurance features in the form of Service-level agreements (SLA). SLAs are negotiated between the users and resource brokers, and contain information about the level of service agreed between the two parties, such as acceptable job start and end times. Brokers need to schedule and execute the user task according to the terms of the agreed SLA. [Sakellariou and Yarmolenko, 2008] [CD-JRA-2.3.4] [CD-JRA-2.3.2] | Grid Brokering is used to automate resource selection in grids. The role of grid brokers is to provide an interface for the users to access grids, accept and understand user jobs, discover resources, find a suitable resource for a job with scheduling, submit jobs to resources and provide the output of the jobs to the user.
