Object Storage Service:Acceleration management

Last Updated:Mar 07, 2025

You can use the transfer acceleration feature, Alibaba Cloud CDN, or the OSS accelerator feature to accelerate access to Object Storage Service (OSS) resources. This topic describes the features, scenarios, and advantages and disadvantages of different acceleration solutions.

Transfer acceleration

OSS uses data centers that are distributed around the world to perform transfer acceleration. When a request to access your bucket is sent, the request is parsed and routed to the data center where the bucket is located over the optimal network path and protocol. The transfer acceleration feature provides an optimized end-to-end acceleration solution for access to OSS over the Internet.

  • Accelerate remote data transfer

  • Accelerate uploads and downloads of gigabyte-size and terabyte-size objects

  • Accelerate the download of dynamic and non-hot data

  • OSS buckets are distributed across the world.

  • Transfer accelerationaccelerates the upload and download of long-distance and large objects.

  • All access requests are redirected to OSS, which consumes the bandwidth of OSS.

  • When a large number of users in the same region access resources at the same time, the transfer accelerationperformance is not as good as that of Alibaba Cloud CDN acceleration.

Alibaba Cloud CDN acceleration

Alibaba Cloud CDN caches static data stored in OSS on points of presence (POPs) that are distributed around the world. When customers access OSS data, data is served from the POPs to accelerate access.

  • Accelerate the download of static and hot data

  • Accelerate on-demand audio and video streaming

  • Accelerate the delivery of small files on websites and applications

  • Alibaba Cloud CDN POPs are distributed across the world.

  • Alibaba Cloud CDN POPs provide high bandwidth.

  • The cache hit ratio is high for resources that are frequently accessed and low for resources that are infrequently accessed. If resources are not cached on POPs, access to the resources is redirected to OSS by using back-to-origin links over the Internet.

  • The accelerationperformance is not as expected for dynamic requests, such as object upload and deletion.
