Alibaba Cloud Object Storage Service (OSS) provides you with network-based data access services. OSS allows you to store and retrieve a variety of unstructured data files, including text files, images, audio files, and video files, over the network at any time.

Before you use OSS, we recommend that you familiarize with OSS usage limits. For more information, see Limits.

OSS uploads data files as objects to a bucket. You can perform the following operations in OSS:

  • Create one or multiple buckets and upload one or multiple objects to each bucket.
  • Share or download an object by using its URL assigned by OSS.
  • Configure the ACL for a bucket or object by modifying its attributes or metadata.
  • Perform basic and advanced OSS operations in the OSS console or by using various convenient tools and SDKs.

Use the OSS console

The following figure shows the steps to perform basic OSS operations in the OSS console.

Use ossbrowser

ossbrowser is a graphical object management tool for OSS. This tool supports the Windows, Linux, and Mac operating systems. You can use ossbrowser to view, upload, and download objects and folders, upload or download objects in resumable mode, or perform GUI-based policy authorization. As a desktop graphical tool, ossbrowser provides lower transmission speed and performance than ossutil. For more information, see Quick start.

Use ossutil

ossutil allows you to use command lines to manage OSS data and supports the following operating systems: Windows, Linux, and Mac. ossutil provides simple commands to efficiently manage buckets and objects and supports concurrent upload tasks. ossutil supports the upload, download, and resumable transmission of objects and folders. For more information, see Quick start.

Use APIs and SDKs

OSS provides APIs and SDKs in multiple programming languages to facilitate secondary development. For more information, see the following links:

For SDK examples in more programming languages, see OSS SDK introduction. For more information about OSS APIs, see OSS API introduction.

Subsequent operations
