一种基础设施云系统——YUN

文章设计了一个虚拟化平台层——YUN系统,介绍了YUN系统的设计目标、系统架构及主要子系统的功能。YUN系统是一种基础设施云系统。YUN系统管理和虚拟化异构、分布的物理资源(包括服务器设备、网络设备、存储设备),并以即付即用的方式将这些资源按需提供给用户使用;通过虚拟化和网络技术,将操作系统功能边界扩展到网络侧,使得终端侧和网络侧能够在一个统一的架构内进行计算和资源的配置、调度、管理,实现网络化操作系统充分、合理地使用和共享网络系统内的资源。

YUN: An Infrastructure-as-a-Service Cloud System

this paper, we design a virtualization platform and introduce the design goal, system architecture, and function of the main subsystems in YUN--an infrastructure-in-a-service cloud system. YUN virtualizes and manages heterogeneous and distributed physical resources such as server, network, and storage devices. Using a pay-as-you-go model, these are exported as on-demand services to customers. Virtualization and network technology extend the functionality of an QS to the network side, enabling both the terminal and network sides to allocate and schedule computing and other resources in a unified manner. Networking operating systems can use and share resources reasonably within the network system
