　　OpenStack服务的名词解释如下

　　Service
服务Project name项目名Description
描述Dashboard
仪表盘HorizonProvides 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。Compute
计算NovaManages 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。Networking
网络NeutronEnables 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 andtechnologies.

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。StorageObject Storage
对象存储SwiftStores 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。Block Storage
块存储CinderProvides 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 servicesIdentity Service
身份识别KeystoneProvides 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。Image Service
镜像服务GlanceStores 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。Telemetry
计量CeilometerMonitors 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 servicesOrchestration
混合云接入HeatOrchestrates 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？？
