CDN (Content Delivery Network) distributes website content to nodes in different regions. In this way, it shortens the distance between the visitor's host and the host that stores the website content, and also solves the problem of slow access speed caused by different operator lines. Embarrassing problems and bring a better experience to users.
High-defense CDN is a network acceleration technology used to improve website performance, accelerate access speed, and defend against DDoS attacks. It caches website content by deploying high-defense nodes to meet users' high-speed access needs. At the same time, high-defense CDN also provides the ability to defend against various network attacks such as DDoS and CC attacks, which can meet the specific needs of different websites and ensure the security and availability of the website. It can be said that today, when network security is increasingly valued, high-defense CDN has become the choice of many enterprise users.
The reason why high-defense CDN has become a safe choice for Internet companies and one of the basic security facilities of various websites is because CDN can bring the following benefits to websites:
Strengthen website security protection. High-defense CDN has the ability to defend against DDoS attacks, CC attacks, malicious crawlers, SQL injection and other network attacks. Different nodes after access to CDN distribution have different IP addresses, which will naturally hide the real IP of the source host. In this way, malicious attacks will be directed to the high-defense node of the CDN to ensure the security of the source machine and achieve security protection effects.
To improve website access speed, High Defense CDN can cache static resources of the website, such as images, etc. to the CDN node, reducing loading time and improving the speed at which users open the website.
Reduce server bandwidth pressure. Through the caching of high-defense CDN, you can reduce the bandwidth occupation of the source machine, thereby reducing the load on the server and reducing server bandwidth costs.
Improve user experience. When users visit a website that supports high-defense CDN, they can significantly improve the loading speed, making the website have better access performance and security performance. This improves the user's access experience and can increase the number of users. stickiness.
Generally speaking, high-defense CDN is a network service that integrates high-defense technology and CDN technology, and can provide efficient, stable, and reliable content distribution and security protection. It can resist various network attacks, such as DDoS attacks, CC attacks, malicious crawlers, etc. It can also improve the opening speed of the website by caching content nearby, ensuring the availability of the origin site and improving the user's access experience. It has been widely used in various Internet services and has become an important part of network security and content distribution.
