OpenStack的架构图：
OpenStack服务的名词解释如下
| Service 服务 | Project name项目名 | Description 描述 |
|---|---|---|
| 仪表盘 | Provides a web-based self-service portal to interact with underlying OpenStack services, such as launching an instance, assigning IP addresses and configuring access controls. 提供一个web界面来操作OpenStack服务，例如：创建实例，分配IP地址，配置访问权限。 | |
| 计算 | Manages the lifecycle of compute instances in an OpenStack environment. Responsibilities include spawning, scheduling and decomissioning of machines on demand. 管理OpenStack环境下的计算资源和它们的生命周期，包括： 生产实例，调度，销毁实例回收资源。 | |
| 网络 | Enables network connectivity as a service for other OpenStack services, such as OpenStack Compute. Provides an API for users to define networks and the attachments into them. Has a pluggable architecture that supports many popular networking vendors and technologies. OpenStack的网络即服务功能，提供API给用户来定义网络和附加功能。提供一个可插入式的架构，与许多流行的网络厂商和技术标准留有接口。 | |
| Storage | ||
| 对象存储 | Stores and retrieves arbitrary unstructured data objects via a RESTful, HTTP based API. It is highly fault tolerant with its data replication and scale out architecture. Its implementation is not like a file server with mountable directories. 存储和检索非结构化的数据对象，通过REST和HTTP的API接口来调用。它有高容错性，高数据的可复制性和扩展性。它的实现不必像文件系统那样必须mount目录。 | |
| 块存储 | Provides persistent block storage to running instances. Its pluggable driver architecture facilitates the creation and management of block storage devices. 提供持久的块设备存储实例。它提供一些可插拔的架构来方便管理块存储设备。 | |
| Shared services | ||
| 身份识别 | Provides an authentication and authorization service for other OpenStack services. Provides a catalog of endpoints for all OpenStack services. 提供鉴别与授权功能，可以在所有的OpenStack服务上提供一个接入点验证。 | |
| 镜像服务 | Stores and retrieves virtual machine disk images. OpenStack Compute makes use of this during instance provisioning. 存储虚拟机磁盘镜像的功能，OpenStack计算服务需要这些镜像来实例化虚拟机。 | |
| 计量 | Monitors and meters the OpenStack cloud for billing, benchmarking, scalability, and statistical purposes. 监控和计量功能，提供OpenStack云计算的账单，性能指标，扩展性和满意度的调查表。 | |
| Higher-level services | ||
| 混合云接入 | Orchestrates multiple composite cloud applications by using either the native HOT template format or the AWS CloudFormation template format, through both an OpenStack-native REST API and a CloudFormation-compatible Query API. 混合云接入功能，提供多种云的功能调用功能，即可以通过调用OpenStack本地化的API接口实现，也可以通过AWS云接口实现？？或者 云的通用格式化的API实现？？神吹的功能？？ |
