cloudstack二次开发内部培训

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-Service

CloudStack 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 Platform

1.2 Cloudstack组成部分

1.3什么是Primary Storage

Primary 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 Storage

Secondary 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

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；

implementations.Remember that each ServerResource should

be deployable in both a management server

and in a remote agent container.

Core is also being converted to be one project per ServerResource, as how ovm is done today.
