Minxian Xu, Adel Nadjaran Toosi, Rajkumar Buyya

TL;DR
This paper introduces iBrownout, an integrated method for reducing energy use and managing overloads in container-based cloud data centers by selectively deactivating application components, demonstrating significant energy savings.
Contribution
The paper presents a novel integrated approach combining brownout techniques with energy management in container-based clouds, validated through real trace evaluations.
Findings
Reduces energy consumption by approximately 40% compared to no power-saving techniques.
Achieves 20% energy savings over brownout-overbooking approach.
Attains 10% energy reduction compared to auto-scaling methods.
Abstract
Energy consumption of Cloud data centers has been a major concern of many researchers, and one of the reasons for huge energy consumption of Clouds lies in the inefficient utilization of computing resources. Besides energy consumption, another challenge of data centers is the unexpected loads, which leads to the overloads and performance degradation. Compared with VM consolidation and Dynamic Voltage Frequency Scaling that cannot function well when the whole data center is overloaded, brownout has shown to be a promising technique to handle both overloads and energy consumption through dynamically deactivating application optional components, which are also identified as containers/microservices. In this work, we propose an integrated approach to manage energy consumption and brownout in container-based cloud data centers. \color{black} We also evaluate our proposed scheduling policies…
