[2026/09/18] Hyeongbin's paper has been published in Journal of Cloud Computing
Hyeongbin Kang, a Ph.D. student at DCLab, has published a paper titled “Asymmetric virtual machine replacement: a multi-objective optimization approach for energy efficiency in cloud data centers” in the Journal of Cloud Computing, an SCIE-indexed journal with an impact factor of 5.5. His paper introduces AVMrP, a multi-objective evolutionary optimization framework for cloud data centers that employs an asymmetric VM replacement strategy — leveraging real-time resource usage observations across heterogeneous servers — to simultaneously minimize power consumption and migration cost while explicitly controlling overcommitment ratios to prevent SLA violations. Congratulations, Hyeongbin! [Paper Link]
