Swift 是一个提供RESTful HTTP 接口的对象存储系统，它是开源云计算平台Openstack 的一个重要组件。Swift 存储具有数据访问灵活、高数据持久性、极高的可拓展性、无单点故障等优势。本文从底层开发SDK分析开始，为对象存储设计构造了模拟文件系统，并对基于开源对象存储的Android 移动网盘客户端开发进行了探讨。

Swift is an object storage system that provides a RESTful HTTP interface. It is an important component of Openstack.Swift storage has the advantages of data access flexibility, high data durability, high scalability, no single point of failure and so on.This article starts with the SDK analysis, then constructs a simulation file system for object storage, and discusses on the development of Android mobile network disk client based on open source object storage.
