Alibaba Cloud OSS: which route are you on?
Alibaba Cloud puts extra requirements on buckets in mainland China, so answer two questions first and then follow the matching guide.
A bucket outside mainland China is the simplest case: no domain, filing or certificate needed.
Step by step
-
Step 1
Where will the bucket live?
- Outside mainland China (Hong Kong, Singapore, Tokyo …) → take route 3, the simplest one.
- Mainland China → answer the next question.
-
Step 2
When was OSS activated?
Three routes
| Route | Who it is for | What you need to prepare |
|---|---|---|
| ① Mainland China, full filing | Bucket in mainland China, OSS activated on or after 20 March 2025 (or unknown) | Your own domain, an ICP filing, an HTTPS certificate |
| ② Mainland China, no filing | Bucket in mainland China, OSS activated before 20 March 2025 | Nothing extra |
| ③ Outside mainland China | Bucket in Hong Kong, Singapore, Tokyo or another overseas region | Nothing extra |
Binding your own domain to the bucket?
Three points from real testing: the domain must CNAME straight to OSS (a domain served through Alibaba Cloud CDN cannot be the endpoint), add the domain in OSS first and let it add the DNS record, and put the certificate in OSS certificate hosting. Details are under “Other cases” at the end of route 1 and route 3.
