What is object storage OSS:
Ali cloud object storage service (Object Storage Service, referred to as OSS), Ali cloud mass is provided, secure, low-cost, highly reliable cloud storage service. It has a RESTful API interfaces and platform-independent, able to provide service 99.99999999 percent of persistence. You can, any time, any place to store and access any type of data in any application. OSS for a variety of sites, development companies and developers.
You can use the API provided by Ali cloud / SDK interface or OSS migration tool easily vast amounts of data into or out of Ali cloud OSS. Data stored in the cloud OSS Ali later, you can select the standard type (Standard) Ali OSS cloud service as a mobile application, large sites, photo sharing or major audio and video storage hot spots, you can also choose a lower cost, longer storage period access type low-frequency (infrequent access) and archive types (archive) Ali cloud OSS service as infrequently accessed data backup and archiving.

Object Storage OSS advantages:
Convenient, efficient use
RESTful API provides a standard interface, a rich SDK package, client tools, console. You can easily upload the same file as the use, download, retrieve, manage massive amounts of data for Web sites or mobile applications.
Any number and size of the file. You can expand storage space as unlimited amount of storage needed to solve the traditional hardware store expansion problem.
It supports streaming writing and reading. Especially for large video and other files on write business scenarios.
Support data lifecycle management. You can customize the batch delete or transferred to lower-cost archiving service expiration data.
Powerful, flexible security mechanism
Flexible authentication, authorization mechanisms. STS URL provides authentication and authorization mechanisms, as well as whitelists and anti-hotlinking function master account.
Provide user-level resource isolation mechanisms and multi-cluster synchronization mechanism (optional).
Rich, powerful value-added services
Picture: support for multiple image formats conversion jpg, png, bmp, gif, webp, tiff, etc., and a variety of operating a thumbnail, crop, watermark, zoom and so on.
Audio and video transcoding: provide high-quality, high-speed parallel audio and video transcoding capabilities, so your audio and video files easily cope with a variety of terminal equipment.
Accelerate content distribution: OSS as the source station, with CDN to accelerate distribution, with a stable, no bandwidth limits back to the source, cost-effective, a key feature of configuration.

使用场景：
OSS主要应用于以下场景：
图片和音视频等应用的海量存储
OSS可用于图片、音视频、日志等海量文件的存储。各种终端设备、Web网站程序、移动应用可以直接向OSS写入或读取数据。OSS支持流式写入和文件写入两种方式，如下图所示：
网页或者移动应用的静态和动态资源分离
利用BGP带宽，OSS可以实现超低延时的数据直接下载。也可以配合阿里云CDN加速服务，为图片、音视频、移动应用的更新分发提供最佳体验，如下图所示：
云端数据处理
上传文件到OSS后，可以配合媒体转码服务(MTS)和图片处理服务（IMG）进行云端的数据处理，如下图所示：
