The price of CDN acceleration and high-defense servers depends on multiple factors, including service provider, required bandwidth and features, etc. Generally speaking, the price of high-defense servers can be relatively high because they usually provide higher network security protection and dedicated resources. The price of CDN acceleration may be more flexible, and billing is based on the required traffic and service scope.

　　Specifically, here are some pricing factors and considerations:

　　Bandwidth cost:

　　High-defense servers usually provide higher bandwidth to cope with possible attack traffic and high load. Therefore, the bandwidth cost of high-defense servers may be higher. The bandwidth cost of CDN acceleration services depends on factors such as the amount of traffic used and traffic distribution.

　　Functions and performance:

　　High-defense servers usually provide more powerful network security protection functions, including anti-DDoS attacks, intrusion detection, and firewalls. These advanced features may result in the relatively high price of high-defense servers. CDN acceleration services mainly focus on content distribution and acceleration, and their prices may vary depending on required functions (such as caching, load balancing, etc.).

　　Service scope and global coverage:

　　CDN services usually have edge nodes with global coverage to distribute content to users around the world. This global coverage can increase the cost of CDN services. High-defense servers are usually deployed in specific data centers or regions, and their prices may vary depending on geographic location.

　　Overall, the prices of CDN acceleration and high-defense servers vary depending on factors such as service providers, required features, and performance. It is recommended to consider these factors based on your needs and budget, and compare with different service providers to choose a suitable solution.
