CDN Product Description
We are discontinuing support for the Akamai provider. Creating new Akamai CDN resources is not available, existing Akamai resources will cease to function and will be deleted in May 2025. We recommend switching to a Selectel provider now to avoid website outages. To connect Selectel CDN, please use the instructions in the section Connect CDN.
A content delivery network (hereinafter CDN) consists of a set of nodes (caching servers), thanks to which the distribution of static content is accelerated. A network of caching servers allows solving problems related to the quality and speed of content delivery to geographically distributed users, including reducing the load on the main servers of web projects.
The product supports user types and roles.
How it works
At the first user request, the file is uploaded to the cache of CDN servers from the main content source server. On subsequent requests for the same file, it is retrieved from the caching CDN servers.
CDN servers do not store data permanently, but cache it for a period of time that depends on how often that data is accessed.
If there are no requests for files for a long time, files from the caching server are deleted automatically. When a new user request is made, the file is downloaded from the main server again.
The cached files are updated depending on the cache settings. By default, the cache lifetime is 24 hours: once every 24 hours, the CDN will access the source and check if the original files have changed. If the files have changed, the CDN will update them by downloading them from the primary server.
