Load balancing

Because the CDN server is at the edge, you can have a clearer understanding of inbound traffic and the status of the source server. This enables CDN to adopt application layer load balancing to improve traffic allocation efficiency by accurately measuring the actual load of each source server.

Website security

CDN abstracts the source server by hiding the identity of the source server, thus protecting the source server from direct attacks on IP addresses and making it easy to manage traffic. Many CDN vendors offer cloud security solutions for ddos, Web application attacks, and spam / robot attacks.

Content storage

Many CDN providers allow customers to store content on the edge server, whether it is a large media file, database file, or script, which can be intelligently distributed on the edge server as needed.
