CDN defense and high defense servers are two different security solutions, each with its advantages and applicable scenarios. Which solution to choose depends on your specific needs and environment. Let me briefly compare their characteristics:

　　CDN defense:

　　Distributed content delivery network: CDN is mainly used to accelerate content transmission. By distributing content to nodes from all over the world to increase user access speed and reduce delay.

　　Edge node defense: Since CDN deploys a large number of marginal nodes worldwide, they can provide a certain degree of defense, disperse and reduce DDOS attacks in specific areas.

　　Applicable to large flow: CDN is usually suitable for dealing with large -scale traffic, and provides a certain relief for unavailable problems caused by excessive traffic.

　　Content cache: CDN reduces the load of the source server by caching static content and improves the overall performance.

　　High defense server:

　　Focus on security defense: High defense server is a server specially designed to resist various network attacks, especially DDOS attacks. They are usually equipped with powerful firewalls, invasion detection systems and other safety equipment.

　　Concentrated defense: High defense servers are concentrated in data centers for defense, which can monitor and prevent attack traffic more comprehensive and in -depth, and provide stronger security.

　　Customized configuration: High -defense servers usually allow users to perform highly customized security configurations to meet specific security needs and threat situations.

　　Suitable for specific defense requirements: If your main attention is network security, especially defense DDOS attacks, high -defense servers may be a more appropriate choice.

　　If you mainly pay attention to increasing the access speed of global users, accelerate content transmission, and defense some smaller DDOS attacks to a certain extent, then CDN defense is a good choice.

　　If you need more powerful and professional network security defense, especially when facing large -scale and complex DDOS attacks, high -defense servers may be more suitable for your needs.

　　The best choice depends on your specific business needs, security risks and budgets. Sometimes, comprehensive use of CDN defense and high defense servers can also provide more comprehensive security protection.
