Why is CDN of advanced anti DDoS the most cost-effective anti DDOS solution? For ddos attacks, people who have worked on websites should be familiar with them. Everyone who has been attacked by ddos will have lingering fear, because this attack is essentially unprepared, or there is no low-cost solution. The full English name of ddos attack is translated into distributed denial of service. Many controlled broilers (computers controlled by trojans) send access requests to websites at the same time, resulting in the exhaustion of bandwidth resources and the inability of servers to access.
According to the current technology development in the industry, there are several ways to defend against ddos.
First, rent extra bandwidth. Generally speaking, ddos attacks can easily reach the level of 10g or so. We know that even the cheapest 10m bandwidth at present costs 100 yuan a month, and renting 10g bandwidth costs 100000 yuan a month. Not to mention, sometimes attacks can reach the 100g level, that is, a monthly bandwidth fee of 1 million yuan. Few enterprises can bear such high costs.
Second, hardware defense. The hardware firewall is used to clear the abnormal traffic of ddos attacks. However, this method can only be used for traffic ddos attacks, such as sYn/AcK attacks, tcp full connection attacks, and script brushing attacks. If the d [Korean server hard defense] dos attack rises to the application layer, the defense capability of the hardware firewall will be weak.
Third, distributed cluster defense technology. In essence, this defense is to distribute the website system in different places and different IP servers [Vietnam VM], so as to disperse the attack traffic of attackers. For example, today's Internet giants have servers deployed all over the country. There are large-scale server clusters in every place, and each cluster has a defense capability of more than 10g. This is why the websites of Internet giants have never been attacked. But only a few Internet giants can afford this approach.
Finally, advanced anti DDoS CDN. The full english name of cdn is content distribution network. By deploying edge node servers at different locations on the network, users can obtain the required content in the shortest distance and time, thus avoiding network congestion and information delay caused by a single node. Because cdn can arrange nodes in the whole network and hide the function of the original server IP address, cdn can not only be used to accelerate network services, but also be used as a server for advanced anti DDoS. Compared with temporarily renting advanced anti DDoS bandwidth, the price of advanced anti DDoS CDN is extremely cheap. For example, the starting price of the company's global advanced defense CDN, 50g defense, is only 2999 yuan per month. Advanced anti DDoS can guarantee 900g at most, only 9999 yuan per month. The cost is less than 1/10 of leased bandwidth defense.
Why is CDN of advanced anti DDoS the most cost-effective anti DDOS solution? What should I pay attention to when renting cabinets in Hong Kong? With the growth trend of Internet servers and sales market, many companies are also looking for better hosting service platforms for Internet servers. Among them, the port network server cabinet rental hosting service platform with free archive space and international network bandwidth is favored by customers.
Frequently asked questions about renting and hosting network server cabinets in Hong Kong:
1. Whether the big data center is safe When choosing Hong Kong cabinet leasing, the first thing to consider is whether the service platform you are hosting has a safe big data center, whether the hardware configuration is complete, and how about the network space. Because a secure big data center is related to the maintenance and operation reliability of the network in the middle and later stages of the server, it should be carefully considered.
2. From the opening speed level of overseas terminals, check whether the terminal rental management center has international network bandwidth, which is rich in network bandwidth and flexible in multiple routes. This will also determine which network space your network server will operate in.
3. Anti attack capability When renting cabinets in Hong Kong, it is also necessary to fully consider whether the big data center has a strong anti attack capability to prevent the network server from being attacked afterwards.
4. In terms of price, when choosing Hong Kong cabinet tenants, we went out to consider the hardware configuration and Internet access level, and price was the key factor. As some service providers make arbitrary pricing, they must shop around before renting Hong Kong counters [focus on the rich and poor roots of game companies], and choose hosting only when they find higher cost performance.
