高防服务器与高防CDN有哪些区别

随着互联网的快速发展，安全问题成为了很多企业和机构面临的大问题。因此，高防措施就应运而生了。然而，在高防领域中，高防服务器和高防CDN是两种常见的防御手段，那么它们之间究竟有什么区别呢？

高防服务器

高防服务器是一种以硬件和软件为主要手段，保护服务器安全的特殊服务器。通常情况下，高防服务器会使用高防线路，抵御大规模的网络攻击。高防服务器能够进行7层和4层的防护，对于各种攻击的拦截和过滤能力都比较强大。

对于一些大流量网站，有可能会遭受到DDoS攻击。这时候，高防服务器就可以发挥作用了。不仅能抵御各种类型的DDoS攻击，还可以根据需要提供高品质、高可靠的DASH、HLS、HTTP流媒体等服务。

高防CDN

高防CDN是一种基于云计算服务器、缓存服务器和DNS等技术实现的高防御服务。CDN是Content Delivery Network（内容分发网络）的缩写。在CDN网络中，会有多台服务器分布在不同的区域，使用户可以快速访问网站，减轻了源站压力。

通过高防CDN服务可以有效降低源站被攻击的风险，高防CDN运营商会使用DDoS防护设备来监测网络流量，一旦发现有DDoS攻击，就会通过限制IP、禁止CC等手段进行防御。

区别

高防服务器的防御能力比较全面，能够抵御各种类型的攻击，性能稳定，适合对大规模DDoS攻击等情况进行应对。而高防CDN基于云计算技术，可以快速响应和升级。当然，高防CDN的防御能力没有高防服务器全面。

除此之外，高防服务器和高防CDN的差异还在于部署位置。一般来说，高防服务器和网站源站部署在同一机房，防御能力更加强大，但价格也较为昂贵。而高防CDN则可以选择部署在全球各地的CDN节点上，可以提供更全面、更稳定的防御服务。

Differences between High Defense Server and High Defense CDN

With the rapid development of the Internet, security has become a major concern for many enterprises and organizations. Therefore, high defense measures have emerged. However, in the field of high defense, high defense servers and high defense CDN are two common defense measures. So, what are the differences between them?

High Defense Server

A high defense server is a special server that protects the security of servers mainly by hardware and software. Generally, high defense servers use high defense lines to resist large-scale network attacks. High defense servers can carry out 7-layer and 4-layer defense and have strong interception and filtering capabilities for various attacks.

For some high-traffic websites, they may be subject to DDoS attacks. At this time, high defense servers can play a role. They can not only resist various types of DDoS attacks, but also provide high-quality, reliable services such as DASH, HLS, and HTTP streaming media as needed.

High Defense CDN

High defense CDN is a high defensive service based on cloud computing servers, caching servers, and DNS technology. CDN is the abbreviation of Content Delivery Network. In the CDN network, multiple servers are distributed in different regions, allowing users to access websites quickly and reducing the pressure on the origin server.

Through high defense CDN services, the risk of the origin server being attacked can be effectively reduced. The high defense CDN operator will use DDoS defense equipment to monitor network traffic. Once a DDoS attack is detected, it will be defended by restricting IP, prohibiting CC, and other means.

Differences

The defense capability of high defense servers is relatively comprehensive, and can resist various types of attacks, with stable performance, suitable for coping with large-scale DDoS attacks and other situations. High-defense CDN is based on cloud computing technology, which can respond and upgrade quickly. Of course, the defense capability of high-defense CDN is not as comprehensive as high-defense servers’.

In addition, the difference between high defense servers and high defense CDN is also in the deployment location. Generally, high defense servers and the website origin server are deployed in the same data center, with stronger defense capabilities, but the price is also more expensive. High defense CDN can be deployed on CDN nodes around the world and can provide more comprehensive and stable defense services.
