To activate CDN for Object Storage (COS), you typically need to follow these steps:

  1. Create a CDN Acceleration Domain: First, you need to create a CDN acceleration domain in your cloud service provider's console. This domain will be used to access your COS resources through the CDN network.

  2. Configure Source Information: After creating the CDN domain, you need to configure the source information. This usually involves specifying the COS bucket that you want to accelerate.

  3. Enable CDN Acceleration: Once the source information is configured, you can enable CDN acceleration for the domain. This will start distributing your COS content through the CDN network.

  4. Update DNS Records: After enabling CDN acceleration, you need to update your DNS records to point to the CDN domain instead of directly pointing to your COS bucket.

  5. Verify Activation: Finally, verify that the CDN acceleration is working by accessing your content through the CDN domain.

Example:
Suppose you have a website that hosts images on Tencent Cloud Object Storage (COS). To improve the loading speed of these images for users around the world, you decide to activate CDN for your COS bucket.

  • You log in to the Tencent Cloud console and navigate to the CDN service.
  • You create a new CDN acceleration domain, e.g., images.yourdomain.com.
  • You configure the source information by selecting your COS bucket as the origin server.
  • You enable CDN acceleration for images.yourdomain.com.
  • You update your DNS records to point images.yourdomain.com to the CDN domain provided by Tencent Cloud.
  • After a short propagation time, you verify that accessing images.yourdomain.com loads the images faster than before.

Recommendation:
For activating CDN for Object Storage (COS) on Tencent Cloud, you can use the Tencent Cloud CDN service. It provides a simple and efficient way to accelerate your COS content delivery, ensuring that your users experience faster access times regardless of their geographic location.
