2、虛擬化的新模式。首先對(duì)云計(jì)算環(huán)境下硬件的虛擬化技術(shù)進(jìn)行分析,然后對(duì)當(dāng)前儀器虛擬化技術(shù)進(jìn)行討論,結(jié)合對(duì)儀器在云計(jì)算環(huán)境中應(yīng)用場(chǎng)景的探索,確定了儀器資源服務(wù)的IAAS模式。通過分析IAAS模式下硬件設(shè)備虛擬化的特點(diǎn),并對(duì)比傳統(tǒng)的儀器虛擬化技術(shù),提出了適用于IAAS云計(jì)算模式下儀器虛擬化的方法。該方法通過推送儀器的連接信息并與儀器建立虛擬連接通道,來實(shí)現(xiàn)儀器在云計(jì)算環(huán)境中的虛擬化,如此,可最大限度地提供系統(tǒng)開發(fā)的靈活度。最后,對(duì)該虛擬化技術(shù)的實(shí)現(xiàn)給出了推薦的架構(gòu),旨在促進(jìn)儀器資源與云計(jì)算環(huán)境的集成與融
