基于Brownout的云应用组件节能调度

Energy Efficient Scheduling of Cloud Application Components with Brownout

Minxian Xu, Amir Vahid Dastjerdi, Rajkumar Buyya

摘要:

云数据中心经常会遇到突发请求等意外负载,这可能会导致过载和性能下降。动态电压频率调整和VM合并已被证明是有效的管理过载。但是,当整个数据中心过载时,它们无法正常工作。Brownout提供了一个有希望的方向,通过配置应用程序暂时降低用户体验来避免过载。此外,还可以应用掉电来降低数据中心的能耗。作为动态电压频率调节和虚拟机整合的补充选项,我们的组合式限电方法通过选择性和动态地停用应用程序可选组件来降低能耗,这也可以应用于自包含的微服务。结果表明,我们的方法可以节省20%以上的能源消耗,并有节能和折扣提供给用户之间的权衡。

英文摘要:

It is common for cloud data centers meeting unexpected loads like request bursts, which may lead to overloaded situation and performance degradation. Dynamic Voltage Frequency Scaling and VM consolidation have been proved effective to manage overloads. However, they cannot function when the whole data center is overloaded. Brownout provides a promising direction to avoid overloads through configuring applications to temporarily degrade user experience. Additionally, brownout can also be applied to reduce data center energy consumption. As a complementary option for Dynamic Voltage Frequency Scaling and VM consolidation, our combined brownout approach reduces energy consumption through selectively and dynamically deactivating application optional components, which can also be applied to self-contained microservices. The results show that our approach can save more than 20% energy consumption and there are trade-offs between energy saving and discount offered to users.
