OpenStack 是一个美国国家航空航天局和 Rackspace 合作研发的，以 Apache 许可证授权，并且是一个自由软件和开放源代码项目。
OpenStack 是一个云平台管理的项目，它不是一个软件。这个项目由几个主要的组件组合起来完成一些具体的工作。
OpenStack 是一个旨在为公共及私有云的建设与管理提供软件的开源项目。它的社区拥有超过 130 家企业及 1350 位开发者，这些机构与个人都将 OpenStack 作为基础设施即服务（简称 IaaS）资源的通用前端。
OpenStack 项目的首要任务是简化云的部署过程并为其带来良好的可扩展性。本文希望通过提供必要的指导信息，帮助大家利用 OpenStack 前端来设置及管理自己的公共云或私有云。
OpenStack 是由 Rackspace 和 NASA 共同开发的云计算平台，帮助服务商和企业内部实现类似于 Amazon EC2 和 S3 的云基础架构服务 (Infrastructure as a Service, IaaS)。OpenStack 包含两个主要模块：Nova 和 Swift，前者是 NASA 开发的虚拟服务器部署和业务计算模块；后者是 Rackspace 开发的分布式云存储模块，两者可以一起用，也可以分开单独用。OpenStack 是开源项目，除了有 Rackspace 和 NASA 的大力支持外，后面还有包括 Dell、Citrix、Cisco、Canonical 这些重量级公司的贡献和支持，发展速度非常快，有取代另一个业界领先开源云平台 Eucalyptus 的态势。
