Skylark:Design and Implementation of a Cloud-Terminal Integrated System

论文介绍了云端一体化系统Skylark,旨在满足用户通过异构终端,随时、随地访问应用和管理数据的需求,使得用户对操作系统平台、硬件设备、应用安装管理的依赖最小化。终端通过SkylarkAPI访问云平台的服务,基于扩展的Spice协议为显示和计算的前后端分离提供高效支持;后端云平台对计算、存储和网络等资源进行虚拟化,基于Xen-IFS文件系统分离和保护用户私有数据;SkylarkManager云管理系统整合前后端业务,对系统资源进行统一管理和调度。Skylark支持Windows、Linux和Android等多种客户端,实现了云中心和各异构终端的一体化。

The paper introduces a cloud - terminal integrated system, Skylark. It aims to meet the needs of application access and data management through heterogeneous terminals, anytime and anywhere. It makes the user dependency of operating system platforms, hardware equipments and the application installation management to the minimal. In the front, terminals access cloud services through the SkylarkAPI, the extended Spice protocol provides efficient support for the separation of the application display and computing. In the back end, the cloud platform virtualizes the resources of computing, storage, network and etc, the XenIFS file system provides separation and protection of the user＇ s private data. The cloud management system, SkylarkManager integrates the front and back ends together and provides unified management and scheduling of system resources. Skylark supports a variety of clients, including Windows, Linux, Android, and etc, which integrates the cloud center and the heterogeneous terminals.
