Everything has two sides, with pros and cons. In this article, we will briefly talk about the characteristics of content distribution networks. We will also briefly talk about the advantages and disadvantages of content distribution networks.
Main features of Content Delivery Network ( CDN):
1. Local Cache acceleration improves the access speed of corporate sites, especially sites containing a large number of pictures and static pages, and greatly improves the stability of sites of the nature mentioned above.
2. Achieve cross-operator network acceleration, ensure that users in different networks can get good access quality, and eliminate the impact of interconnection bottlenecks between different operators.
3. Based on DNS load balancing technology, the Cache server is intelligently and automatically selected, which can be accelerated remotely. Remote access users can choose the fastest server to speed up remote access.
4. Automatically generate a remote Mirror (mirror) cache server for the server, which can reduce the bandwidth of remote access, share network traffic, and reduce the load on the original site server.
5. Cluster anti-attack. The widely distributed CDN nodes and the intelligent redundancy mechanism between nodes can effectively prevent hacker intrusions and reduce the impact of various DDoS attacks on the website, while ensuring good service quality.
Disadvantages of Content Delivery Network ( CDN):
The worst part is that it may cost you money, but it adds some complexity to your deployment process.
Advantages of Content Delivery Network ( CDN):
First let’s talk about, when to use CDN? A Content Delivery Network ( CDN) will be most effective when you have a popular public website with some kind of static content (images, scripts, CSS, etc.) .
Secondly, is CDN a performance enhancer? Overall, yes. When a user makes a specific request, the server closest to the user is dynamically determined based on the minimum number of nodes between the server and the user. This optimizes the speed of delivery of content to that user.
Another thing to consider (which has been thrust upon us recently): clients may block the CDN! Some customers use network filter blocking that results in having to manually whitelist them.
In traditional dynamic system access, the user’s request process to the network generally needs to be transmitted through multiple routers in the network, and finally the request is handed over to the dynamic system for processing. However, due to the “best effort” of the IP network itself, “Principle”, the complex environment in network links and the unreliability of hardware do exist, resulting in the current situation of users sending repeated requests, and the user’s requests appear to wait during the submission process, and the data loading time is too long. The ubiquity of CDN distribution solutions solves the performance and reliability issues associated with static websites and the unique challenges associated with delivering static and dynamic elements and applications in today’s online business experience. SpeedNet’s dynamic websites Speed up to solve it. It can effectively prevent the slowness of these online submission systems from directly affecting the work efficiency of office workers. This is also the most common problem that restricts the information construction of many large enterprises in collaborative office OA, ERP, SAP and other information construction.
The times are constantly developing and moving forward. In the future, our science and technology will become more and more advanced. Just like what we have seen in the principles of Marxism, everything is spiraling, twists and turns, and everything has contradictions. sex. While we enjoy the dividends of the content distribution network, we must also be good at accepting its shortcomings. After all, nothing is perfect in this world.
