应用虚拟化技术研究进展

摘要

Application virtualization is a key technology to support the software as a service.This paper an-alyzes and gives out the definition of application virtualization,discusses the advantages and research sta-tus of applicatio virtualization,and points out that the current application virtualization research is mainly centred on implementation issues,but negligent of the service quality of application virtualization.From the angle of platform dependence and distributed architecture,the application virtualization can be divided into homogeneous or heterogeneous application virtualization and local or remote application virtualization. And the paper analyzes the different types of application virtualization implementation principles in detail as well as the corresponding typical application virtualization software and their characteristics.Subse-quently,the paper approaches the service quality evaluation method of application virtualization from the perspective of evaluation indicators and evaluation methods.Finally,aimed at the challenges faced by the service quality of application virtualization,the paper presents the research trends in application virtualiza-tion.%应用虚拟化是支撑软件即服务的关键技术。分析并给出了应用虚拟化的定义，探讨了应用虚拟化的优势及研究现状，指出当前应用虚拟化研究主要集中于实现问题，缺乏对应用虚拟化服务质量的研究。从平台依赖性和分布式架构角度将应用虚拟化分为同构或异构应用虚拟化以及本地或远程应用虚拟化，详细分析了不同类型应用虚拟化的实现原理，存在的典型应用虚拟化软件及其特点。从评测指标和评估方法角度探讨了应用虚拟化服务质量评估方法。最后，针对应用虚拟化在服务质量方面面临的挑战，提出应用虚拟化的研究趋势。
