摘要
In this letter, we propose DVFaaS , a per-core DVFS framework that utilizes control systems theory to assign just-enough frequency for the purpose of addressing the QoS requirements on serverless workflows comprising unseen functions. DVFaaS exploits the intermittent nature of serverless workflows, which enables staged control on distinguishable functions, which jointly contribute to the end-to-end latency. Our results show that DVFaaS considerably outperforms related work, reducing power consumption by up to 22%, with 2x fewer QoS violations.
