The Science of Acceleration
NetDNA splits delivery into four zone types. Pick one per workload instead of forcing everything through a single proxy.
| Zone | How files get to the edge | Best for | Guide |
|---|---|---|---|
| Pull | Fetched from origin on miss | WordPress, Magento, static sites | What is a pull zone |
| Push | You upload via FTP or API | Downloads, large libraries | What is a push zone |
| VOD | Pull or push of video objects | Catalog video, HDDN | What is a VOD zone |
| Live | Ingest + edge fan-out | Events, 24/7 streams | What is a live zone |
Create zones in the control panel. Support how-tos live under pull, push, VOD and live.
What is a CDN pull zone?
A pull zone fetches a file from your origin the first time it is requested, stores it on the edge, and serves later hits from cache. It is the default for websites.
When do I need a push zone?
When you want to upload files yourself (builds, ISOs, video mezzanines) instead of waiting for a visitor to trigger an origin fetch.
Can one account have all four zone types?
Yes. Pull, push, VOD and live are separate zone types in the NetDNA control panel.
