cloudstack 二次开发内部培训.docx

1 Cloudstack介绍及基础 1.1什么是cloudstack官方：CloudStack is an open source cloud compute platform used to deliver Infrastructure-as-a-ServiceCloudStack is open source software written in java that is designed to deploy and manage large networks of virtual machines, as a highly available, scalable cloud computing platform. CloudStack current supports the most popular hypervisors VMware, Oracle VM, KVM, XenServer and Xen Cloud Platform1.2 Cloudstack组成部分1.2.1整体组成1.2.2官方的系统架构1.3什么是Primary StoragePrimary storage is associated with a cluster, and it stores the disk volumes for all the VMs running on hosts in that cluster. 1.4什么是Second StorageSecondary storage is associated with a zone, and it stores the following: Templates OS images that can be used to boot VMs and can include additional configuration information, such as installed applications ISO images disc images containing data or bootable media for operating systems Disk volume snapshots saved copies of VM data which can be used for data recovery or to create new templates 2架构2.1组件级架构2.2 部署架构3工程结构3.1工程依赖关系说明:util是各个工程的基础工具包，给它们提高诸如网络连接、数据库访问、日志等服务；Api 提供了接口服务；Agent 主要与物理主机交互并完成与server的通信；Server 管理端，将管理的资源持久化，提供UI管理；Core 核心业务实现；Cloud-ovm、cloud-vmware-base 分别为oracle vm及 vmware实现，agent-simulator为测试的模拟器；3.2 工程作用NoProjectPackage NamePurposeNotespriority1utilscloud-util.jarutilities methods that can be used in any projectB2apicloud-api.jarREST API, Agent API, and Java API definitionsA3corecloud-core.jarServerResource implementations.Remember that each ServerResource should be deployable in both a management server and in a remote agent container.
