A Multi-CDN is the combination of multiple CDNs (content delivery networks) from different providers into a single network.

Different CDN vendors allow users access to different networks of edge servers or Points of Presence (PoPs), different underlying network infrastructures, and different sets of specialized features and functions.

Therefore, different CDN vendors may deliver different performance, security, and cost benefits too depending on traffic, workload and geo location.

Multi-CDN allows organizations to use “the best CDN for the job” by directing specific traffic and workload to specific CDNs.
