提出兼顾性能、碳排放与废水的FaaS云调度框架
A Framework for SLO, Carbon, and Wastewater-Aware Sustainable FaaS Cloud Platform Management
- 三目标联合优化：服务等级、碳排放、废水
- 发现性能优先调度会加剧碳排与耗水
- 适合关注绿色计算的云平台管理者
函数即服务（FaaS）是一种快速发展的云计算范式，有望降低用户成本。然而，其环境影响尚未受到足够重视。本文从可持续性角度研究FaaS的调度与伸缩问题，发现服务等级目标（SLOs）与碳排放存在冲突，且以SLO为导向的调度可能加剧数据中心的用水量。为此，我们提出一种新型可持续性导向的FaaS调度与伸缩框架，旨在协同优化SLO性能、碳排放和废水生成。该框架可为绿色云平台管理提供理论支持与实践工具。
原文摘要 · Abstract (English)
Function-as-a-Service (FaaS) is a growing cloud computing paradigm that is expected to reduce the user cost of service over traditional serverful approaches. However, the environmental impact of FaaS has not received much attention. We investigate FaaS scheduling and scaling from a sustainability perspective in this work. We find that the service-level objectives (SLOs) of FaaS and carbon emissions conflict with each other. We also find that SLO-focused FaaS scheduling can exacerbate water use in a datacenter. We propose a novel sustainability-focused FaaS scheduling and scaling framework to co-optimize SLO performance, carbon emissions, and wastewater generation.
