Dynamic Load Balancing of Virtualized Database Services Using Hints and Load Forecasting |
Abstract | ||
---|---|---|
Future database application systems will be designed as Ser- vice Oriented Architectures (SOAs), in contrast to today's monolithic architectures. The decomposition in many small services allows the us- age of hardware clusters and a flexible service-to-server allocation but also increases the complexity of administration. Thus, new adminis- tration techniques like our self-organizing infrastructure are necessary. It monitors the system, reacts automatically on exceptional situations, e.g., overload of a server, and features self-optimizing capabilities. In the context of distributed services it takes some time until the reac- tion on an exceptional situation becomes effective. During this time the server stays overloaded which leads to a poor performance of services running on this server. In this paper, we present a novel concept to improve self-organizing infrastructures to react proactively. For this pur- pose we present two techniques: Short-term load forecasting for services with periodic behavior and exploitation of hints from administrators, e.g., resource consumptions, for irregular events. With these techniques our system reacts proactively on imminent overload situations before they actually appear, thus avoiding overload situations. The quality of higher-level services, like enterprise resource planning (ERP) systems, can be improved by running on this proactive platform. We used our prototype implementation to perform comprehensive simulation studies, which demonstrate the effectiveness of our approaches. |
