In IaaS cloud environments, peak memory demand caused by hotspot applications in Virtual Machine (VM) often results in performance degradation within and outside of this VM. Some solutions such as host swapping and ballooning for memory consolidation and overcommitment have been proposed. These solutions, however, have no help for addressing guest swapping issues inside VM. Even though host holds...
With the increasing number of Internet businesses put in the data center, the great importance of server consolidation and hardware integration are highlighted. Among common hardware resources, the consolidation of memory is one of the classic problems, which has been widely studied. Some of the consolidation technologies, such as memory balloon driver and inter-VM page sharing, have been exploited...
As an important aspect of the hardware resource consolidation in virtualization environment, memory consolidation and over-commitment has been motivated by the increasing elastic computing cloud platform. The most popular consolidation technology, Memory Balloon, might introduce serious performance penalty with thrashing when guest memory usage changes dramatically. In order to overcome the drawback...
