10 ways to avoid cdn problems in rush hour in guangzhou? In video streaming media, it is good to have problems due to the popularity of the platform. Maybe you use a world-class cdn. However, during large-scale competitions, when the cdn server and peer traffic reached saturation, some users still could not enjoy a smooth experience. Because each cdn has limited capacity, it has its limitations. Every cdn is a black box, which can hardly provide available capacity information at any specific time. Therefore, the actual performance of cdn in large events is unpredictable, especially when different content providers play live video of events. You will find that you are actually competing with other content providers to share the scarce resource of cdn.
Cdn providers are not perfect. They often return Http errors, and some give priority to important or aggressive customers. Contact your cdn provider, prepare the data (mentioned in the first method), and ask them to provide better performance for your large-scale activities. If your cdn provider fails to solve the problem and meet your expectations, please consider using cdn instead! Now it is not a big trouble to change the CDN. Usually only a few company centers are needed, and sometimes they cooperate with commercial CDNs. If you run your own cdn, be careful to add some additional servers just in case. Start more instances before it is too late. A more interesting approach is the ability to remove the highest format standards in an emergency (capacity issues). [Korean Physical Server] The ABR algorithm is very greedy, which means that every player will try to grab as much bandwidth from the cdn as possible to obtain the highest possible video quality. Each player is independent and will not "know whether the [US Cloud VPS]" server is under too much pressure, or how many other users are currently requesting video clips. It is very likely that all players are competing for the same highest format standard, but no one can do it in the end (considering the prisoner's dilemma). Similarly, this is not an ideal scenario, but when something bad starts to happen, it may be very useful to have a failsafe measure that can eliminate replication.
10 ways to avoid cdn problems in rush hour in guangzhou? Understand the limit of -, and carry out stress test in advance. Unfortunately, there is no perfect solution for global stress testing. Comprehensive solutions like LoadRunner will create thousands of requests and send them to your cdn, but these requests usually come from several servers in the same data center, and they have good connections with your cdn. You can't really test your cdn in very large scale or difficult areas, which will be very expensive and time-consuming. The best solution we found is to use the real data of previous large-scale events to carefully study the weak points identified in the first method. What factors will affect the stability of servers in Hong Kong? The stability of rented servers will directly affect the stability of websites, thus affecting the ranking of websites. The instability of the leased port server [the ECS solution for digital marketing] will directly lead to the interruption of website services, which will lead to the decline of website ranking. If it is serious, it will directly lead to the website [What are the advantages for foreign trade companies to rent Hong Kong VPS] being handled by K station. What factors affect the stability of Hong Kong servers?
1. Data center environment
The server needs to be stored in the data center. The environment of the data center will directly affect the stability of the server. Generally, the data center has a perfect system to ensure the long-term continuous operation of the server. Generally, the data center will be equipped with various hardware equipment, such as generator sets, constant temperature swing, automatic fire extinguishing devices, etc., to avoid some factors that cause the server to fail to operate normally.
2. Line
Different lines will affect the stability of the network to a certain extent. If it is due to insufficient bandwidth or line problems. It will directly affect the stable operation of the server because Hong Kong has many international line resources, most of which are international BGP lines. Therefore, when Hong Kong and servers are selected, the stability of BGP lines is relatively good.
3. Network attack
Network attack is also a factor that affects the stability of the server. Once a network attack occurs, especially a DDOS attack, even if the server has enough bandwidth, it will also affect its stability to a certain extent. Therefore, in the face of industries vulnerable to network attacks, when choosing servers, we can try to choose Hong Kong and servers, and choose advanced defense royal. In this way, even if there is an attack, it will not have a great impact on our own business.
