{"product_id":"9783836488754","title":"A Framework for Sla-Aware Execution of Grid-Based Workflows","description":"Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing, as they serve as a foundation for reliable and predictable Grids. SLAs define an explicit statement of expectations and obligations in a business relationship between provider and customer. Thus, SLAs should guarantee the desired and a-priori negotiated Quality of Service (QoS), which is a mandatory prerequisite for the Next Generation Grids. The complexity of an SLA-based workflow grows significantly, as characteristics of correlated sub-jobs, the data transfer phases, the deadline constraints and possible failures have to be considered. Thus, an architect for an SLA-aware workflow implementation needs sophisticated mechanisms for specification and management, sub-job mapping, data transfer optimization and fault reaction. Therefore, this book presents a system for SLA-aware Grid workflows. The main contributions include an improved specification language for SLA-aware workflows, three mapping and optimization algorithms for sub-job assignment to Grid resources, an error recovery mechanism, and a prototype imple­mentation using standard middleware.","brand":"VDM Verlag Dr. Mueller E.K.","offers":[{"title":"Default Title","offer_id":47041459880176,"sku":"9783836488754","price":89.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783836488754_p0.jpg?v=1763688432","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783836488754","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
