Binding a custom domain allows your end users to download objects from a specific Object Storage bucket using the domain you specify. If you do not need a custom service domain, you can skip this step. Object Storage provides an endpoint domain (supporting S3), which end users can use directly to download objects.
The main functions and benefits of binding a domain are as follows:
Binding a domain is optional and depends on your actual use case. Below, you will find scenarios for accessing Object Storage. If you are using the CDN + Object Storage solution, you usually need to complete domain binding.
The customer wishes to leverage CDNetworks’ global acceleration network to significantly improve end-users’ download speed, reliability, and concurrency, while offloading pressure from the origin bucket.
1. Bind CDNW CDN acceleration domain to bucket.
2. In the CDN configuration, set the bucket as the origin.
The customer already uses or prefers another CDN service provider and wishes to accelerate access to Object Storage content through this third-party CDN.
1. Bind third-party CDN domain to bucket.
2. In third-party CDN configuration, set the bucket as the origin.
The customer does not require or is unsuitable for CDN acceleration, or wishes to use their own branded, memorable domain.
1. Bind customer’s own domain to the bucket.
2. Set up a CNAME record pointing to the bucket. Object Storage provides two types of domain names for CNAME configuration: the Endpoint domain (supports S3) and an assembled origin domain (CNAME Domain) provided by CDNetworks. You can choose either one for your CNAME setup.
For information on how to obtain relevant domain names, please refer to Obtain Domains.
Using Object Storage’s default Endpoint Domain meets the requirements.
1. User can download object by using the Endpoint domain of the specific bucket
2. Integrate the Endpoint domain into your API or web portal as required.
