High defense IP(Anti-DDoS IP) and high defense CDN(Content Delivery Network) are both technologies used to defend against distributed denial of service (DDoS) attacks, but they have some differences in application methods and functions. Let's take a look at the main differences:
High security IP:
Directional defense: High-defense IP addresses are used to protect specified IP addresses from DDoS attacks. The IP addresses of servers are protected.
Attack traffic cleaning: High-defense IP addresses use traffic cleaning to identify and filter out malicious traffic and ensure that only legitimate traffic can reach the server.
Protected objects: High-security IP addresses are used to protect a single server, website, and application.
High defense CDN:
Global Distribution: Highly protected CDNS distribute content to servers located in different geographic locations for faster load times and a better user experience.
Caching and acceleration: A high-defense CDN caches static resources such as images, CSS, JavaScript, etc., allowing them to load more quickly from the nearest server, reducing the load on the source server.
DDoS protection: High-defense CDNS often include DDoS protection to some extent against small-scale DDoS attacks, but their primary goal is to provide content distribution and acceleration, rather than active DDoS protection.
Protected objects: High-defense CDN is suitable for distributing static and dynamic content, enabling faster delivery of content to users, while also providing a certain degree of DDoS protection.
In summary, high-defense IP focuses on protecting a single IP address from DDoS attacks, while high-defense CDN focuses on content distribution and acceleration, with a certain degree of DDoS protection. Which technology you choose to use depends on your needs and application scenarios. In cases where you need to protect your servers from DDoS attacks and provide content distribution, you might consider using both a high-defense IP and a high-defense CDN for more comprehensive protection.
