Optimize your CDN population costs and leverage direct connectivity to select CDN providers.
What is CDN Interconnect?
CDN Interconnect allows select CDN providers to establish direct peering links with Google's edge network at various locations.
How do I set up CDN Interconnect?
If your CDN provider is already part of the program, you don't have to do anything. Traffic from supported Google Cloud locations to your CDN provider automatically takes advantage of the direct connection and reduced pricing.
Work with your supported CDN provider to learn what locations are supported and how to correctly configure your deployment to use intra-region egress routes.
If your CDN provider is not part of the program, contact your CDN provider and ask them to work with Google to get connected.
Typical use cases for CDN Interconnect
High-volume egress traffic
If you're populating your CDN with large data files from Google Cloud, you can automatically optimize this traffic and save money by using the CDN Interconnect links between Google Cloud and selected providers.
Frequent content updates
Cloud workloads that frequently update data stored in CDN locations benefit from using CDN Interconnect, because the direct link to the CDN provider reduces latency for these CDN destinations.
For example, if you have frequently updated data served by the CDN originally hosted on Google Cloud, you might consider using CDN Interconnect.
The special pricing for your traffic egressing from Google Cloud to a CDN provider is automatic. Google works with approved CDN partners in supported locations to whitelist provider IP addresses. This means that any data you send to your whitelisted CDN provider from Google Cloud is charged at the reduced price.
Traffic between Google Cloud Platform and pre-approved CDN Interconnect locations is billed as follows:
- Free for all regions.
The following egress rates only apply to data leaving Google Compute Engine or Google Cloud Storage.
Intra-region pricing for CDN Interconnect applies only to intra-region egress traffic that is sent to CDN providers approved by Google at specific locations approved by Google for those providers.
Consult with your CDN provider to verify that they are an approved provider and, if so, which of their CDN locations are approved for this program. They can help you set up your deployment to use intra-region egress routes when using Google Cloud as the origin source.
