Configuring CDN with IBM Cloud Object Storage

{: #configure-cdn-with-ibm-cloud-object-storage}

You can use {{site.data.keyword.cloud}} Content Delivery Network (CDN) to quickly and securely deliver the website assets (images, videos, documents) hosted and served on the IBM Cloud Object Storage to users around the world.

Before you begin

{: #cos-before-you-begin}

Before you begin using CDN with IBM Cloud Object Storage (ICOS), you'll first need to store objects with public access in {{site.data.keyword.cloud_notm}} Object Storage.

Create a CDN instance with ICOS

{: #create-a-cdn-instance-with-icos}

  1. Follow the guidelines to create a CDN instance with Object Storage type of origin to configure your S3 Endpoint and Bucket name with public access objects stored in the ICOS.
  2. Follow the guidelines to get your CDN instance into RUNNING status.
  3. Access your ICOS objects with CDN URL: http://<hostname>/<path>/index.html.

FAQs for CDN with ICOS

{: #faqs-for-cdn-with-icos} {: faq}

Can I use ICOS private endpoints for CDN?

{: #use-objects-stored-in-icos}

No. The CDN edge servers can only access the ICOS public endpoints, so objects in the ICOS buckets should provide public access.

Will traffic sent from ICOS to CDN be charged?

{: #traffic-from-icos-to-cdn-charge}

Yes. The CDN and ICOS don't have a way of measuring each other's traffic, so both traffic from ICOS and CDN are charged.

How does the CDN edge server retrieve content from the ICOS objects?

{: #cdn-edge-server-retrieve-content}

The CDN uses the S3 endpoint to access the ICOS objects, and replaces the path in the url to the bucket name. For example, if your ICOS S3 endpoint s3.us-south.cloud-object-storage.appdomain.cloud with bucket name xyz-bucket-name is added in path /example-cos/*, when you open the CDN URL www.example.com/example-cos/*, the CDN edge server retrieves the content from s3.us-south.cloud-object-storage.appdomain.cloud/xyz-bucket-name/*.

How do I use the ICOS default index page with CDN?

{: #using-icos-default-index-with-cdn}

The CDN does not support the default index page for the ICOS objects because the ICOS S3 endpoint does not have the default index. You must specify the complete request path in the browser's address bar (for example, www.example.com/index.html). If you want the CDN to automatically access the default index page of the ICOS, create a CDN with Server type of origin instead of an Object Storage type. For example, if you have a ICOS with static website hosting endpoint xyz-bucket-name.s3-web.us-south.cloud-object-storage.appdomain.cloud, you can create a CDN www.example.com with server type of origin xyz-bucket-name.s3-web.us-south.cloud-object-storage.appdomain.cloud in path /*, when a user opens the CDN URL www.example.com, the CDN edge server retrieves the content from xyz-bucket-name.s3-web.us-south.cloud-object-storage.appdomain.cloud/, and ICOS will return your default index page.
