Through virtualization, multiple virtual machines (VMs) can coexist and operate on one physical machine. When virtual machines compete for memory, the performances of applications deteriorate, especially those of memory-intensive applications. In this study, we aim to optimize memory control techniques using a balloon driver for server consolidation. Our contribution is three-fold: (1) We design and...
Service downtime is inevitable in migrating ongoing virtual machine. It is obvious that service downtime impacts the quality of live virtual machine migration. In this paper, a strategy of reducing downtime by reconfiguring memory space is proposed. It employs algorithm AMP-LvMrt to predict the potential number of inconsistent frames to be duplicated at the stop-and-copy stage followed by performing...
Big data refers to data that is so large that it exceeds the processing capabilities of traditional systems. Big data can be awkward to work and the storage, processing and analysis of big data can be problematic. MapReduce is a recent programming model that can handle big data. MapReduce achieves this by distributing the storage and processing of data amongst a large number of computers (nodes)....
