OSS supports three methods to accelerate object access. Choose based on where your users are located and your latency requirements.
Choose a method
| Method | Best for | How it works |
|---|---|---|
| Select a region | Users concentrated in one geography | Reduces physical distance between client and data |
| Transfer acceleration | Users distributed globally or cross-continent transfers | Routes requests over an optimized global network |
| CDN | Frequently accessed static content served to end users | Caches 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.
