摘要： 云计算和互联网的兴起不仅带来了数据中心的变化,也带来了软件的开发、部署、运维和使用上的变革。随着当前云计算和网络环境的不断完善,传统软件如何更好地利用云计算平台并服务于终端用户是计算机软件领域的研究热点,具有广泛的现实意义。近年来,随着实时互联网、微服务、云端渲染、容器等技术和理念发展的不断深入,软件(Software)形态将进一步朝着云件(Cloudware)形态的方向发展。文中主要探究了在云计算和互联网环境下“云件”这一新型软件范型,并针对该软件范型提出了一种新型的云操作系统:GalaxyOS。GalaxyOS可以在不修改传统软件的情况下直接将软件部署到云端运行,并通过浏览器实时投射到终端用户,实现传统软件的新型服务模式。通过采用微服务架构设计,使得该云操作系统具有较好的可扩展、容灾性和灵活配置等特性。通过对实际的GalaxyOS原型系统的实现和交互时延及资源占用进行实验,验证了所提方法在用户体验上的有效性。
