Object Storage Service:How do I accelerate access to OSS objects?

Last Updated:Mar 19, 2026

OSS supports three methods to accelerate object access. Choose based on where your users are located and your latency requirements.

Choose a method

MethodBest forHow it works
Select a regionUsers concentrated in one geographyReduces physical distance between client and data
Transfer accelerationUsers distributed globally or cross-continent transfersRoutes requests over an optimized global network
CDNFrequently accessed static content served to end usersCaches content at edge nodes close to users

Select a region

Place your bucket in the region closest to the majority of your users. When selecting a region, weigh both cost and location of the requests to the bucket.

For guidance on choosing a region, see Choose an OSS region.

Enable transfer acceleration

Transfer acceleration routes requests to your bucket over an optimized global network path. To use it, enable transfer acceleration on your bucket, then update your application to use the acceleration endpoint instead of the default endpoint.

For setup instructions, see Transfer acceleration.

Use CDN to accelerate access

If you have Alibaba Cloud Content Delivery Network (CDN) activated, CDN caches your OSS objects at edge nodes distributed globally. Later requests for the same object are served from the nearest edge node, reducing latency.

For setup instructions, see Use CDN to accelerate access to OSS.
