She平台架构
She是构建在docker/k8s之上、用于软件开发调试的大数据平台，平 台本身是架构在大数据集群之上的分布式系统，包括三层：计算资源管 理层、She核心调度层、应用层，应用层集合了所有课程环境，Devfile 和Workspace是其中两个核心概念：
1.Devfile是开展某项软件类开发任务所需环境的定义，那么将这个草稿 建设起来的就是Workspace，即Workspace是物理的、而Devfile是逻辑 的、是静态的：Workspace包括了物理上运行的各容器或物理机实体、端 口、命名等一干看得见摸得着的资源，所以Devfile定义了某个实训任务 的资源需求情况，如CPU、GPU、Memory、Disk等，而运行中的Work space的则实际占有了这些资源，因此，从这个意义上看，具体的实训 任务决定了She平台的硬件配置需求。
2.Devfile是She平台的预置环境，即其对应的Workspace中已经安装了 一系列版本号确定的工具，这些工具集的选择是根据这项开发任务的通 用需求而定的，是通用的；但是我们可以根据需要卸载、升级、安装相 应工具。
HFS三节点集群拓扑结构
为了降低实训成本，我们以三节点为例搭建HFS集群，但这个集群理论上可以水平扩展到10万点的规模。
