Abstract

The emergence of Big Data has had a profound impact on how data are analyzed. Open source distributed stream processing platforms have gained popularity for analyzing streaming Big Data as they provide low latency required for streaming Big Data applications using Cloud resources. However, existing resource schedulers are still lacking the efficiency and deadline meeting that Big Data analytical applications require. Recent works have already considered streaming Big Data characteristics to improve the efficiency and the likelihood of deadline meeting for scheduling in the platforms. Nevertheless, they have not taken into account the specific attributes of analytical application, public Cloud utilization cost and delays caused by performance degradation of leasing public Cloud resources. This study, therefore, presents BCframework, an efficient deadline-aware scheduling framework used by streaming Big Data analysis applications based on public Cloud resources. BCframework proposes a scheduling model which considers public Cloud utilization cost, performance variation, deadline meeting and latency reduction requirements of streaming Big Data analytical applications. Furthermore, it introduces two operator scheduling algorithms based on both a novel partitioning algorithm and an operator replication method. BCframework is highly adaptable to the fluctuation of streaming Big Data and the performance degradation of public Cloud resources. Experiments with the benchmark and real-world queries show that BCframework can significantly reduce the latency and utilization cost and also minimize deadline violations and provisioned virtual machine instances.
