Hierarchical Cloud Service Workflow Scheduling Optimization Schema Using Heuristic Generic Algorithmg

The rapid growth of visualization technologies and Cloud computing have opened a new paradigm for utilizing the existing resource pools for on-demand and scalable computing, which enables the workflow management system to meet quality-of-service (QoS) requirements of the applications. It becomes crucial for cloud customers to choose the best Cloud services in order to minimize the running costs, and how to match and select the optimum cloud service will be a challenge problem. In this paper, we present an efficient Cloud services workflow scheduling and optimization schema using heuristic generic algorithm, and focus on the hierarchical Cloud service workflow scheduling, Cloud workflow tasks parallel split, syntax and semantic based Cloud workflow tasks matching algorithm, and multiple QoS constraints based Cloud workflow scheduling and optimization, and also presents the experiment conducted to evaluate the efficiency of our algorithm. Streszczenie. Rozwoj technik wizualizacji I wykorzystanie chmury w obliczeniach komputerowych otworzylo problem jak wykorzystac zasoby danych do obliczen skalowalnych i na zyczenie. Dla klientow chmury jest bardzo wazne wybor jak najlepszego serwisu dla minimalizacji kosztow. W artykule zaprezentowano skuteczne planowanie przeplywu serwisow w chmurze przy uzyciu algorytmu genetycznego. (Optymalizacja planowania przeplywu hierarchicznego serwisow w chmurze przy wykorzystaniu algorytmu genetycznego).
