A Primer on Content Delivery Networks

Ustream has written a primer on the basics of content delivery networks (CDNs).

They write, “Video streaming and delivery is a resource intensive process.

For companies, this can result in bottlenecks from the servers hosting or unnecessary costs to scale a server infrastructure.

This piece talks about the basics of delivering content over the Internet before why it’s important to have a CDN when streaming video content.”
