Google Cloud's Media CDN (content delivery network) now has more than 100Tbps of egress capacity.

As reported by Streaming Media Blog, the company's Media CDN offering is continuing to grow and add new functionalities.

The Media CDN uses Google's Edge network, leveraging the same infrastructure that YouTube uses to serve customers with high-volume media, large file dowloads, and live streaming.

According to Google's Media CDN overview, its Edge cache is usually made up of "server infrastructure that stores content closer to end users, located within points of presence (PoPs) or partner ISPs." Using this enables customers to reduce load on its origin infrastructure.

Google adds: "You can use Media CDN with your existing origin infrastructure, whether the content is hosted within Cloud Storage, in another cloud, or within your on-premises infrastructure."

For video on demand, the cache hit ratio of Google Media CDN averages 98.5-99 percent, and for live streaming 96.5-98.5 percent.

Media Streaming Blog writer Dan Rayburn said that while Google's Edge network has more than 3,179 locations worldwide, the Media CDN is not necessarily deployed in all those locations. The Media CDN team can, according to Rayburn, add capacity across those locations depending on customer needs.

Google is set to add a new Flexible Shielding capability to its Media CDN, which enables customers to use specific shield node locations. It already offers "Cloud Armor" services for WAF and DDoS protection.

Rayburn noted that Google shared a list of client names using their Media CDN for streaming and software downloads, but he was not given permission to share them. Among those he does include are Warner Bros Discovery and Major League Baseball.

Google launched its Media CDN in April 2022.
