Preference-based Multiobjective Virtual Machine Placement: A Ceteris Paribus Approach
This work addresses efficiency in cloud resource management for data center operators, but it is incremental as it builds on existing NSGA-II methods.
The paper tackles the virtual machine placement problem in cloud data centers by incorporating Ceteris Paribus preferences into a multiobjective optimization framework, proposing an NSGA-II variant that returns preferred solutions with almost no extra time cost.
This work adopts the notion of Ceteris Paribus (CP) as an interpretation of the Decision Maker (DM) preferences and incorporates it in a constrained multiobjective problem known as virtual machine placement (VMP). VMP is an essential multiobjective problem in the design and operation of cloud data centers concerned about placing each virtual machine to a physical machine (a server) in the data center. We analyze the effectiveness of CP interpretation on VMP problems and propose an NSGA-II variant with which preferred solutions are returned at almost no extra time cost.
