The importance of accelerating CDN

In today's society, the emergence of each technology, are designed to solve real social problems, improve the convenience of life, social needs determine the direction of development and application of technology. Similarly, the reason why there will be accelerated CDN, are also to address the needs in the real world.
1. Because trans-regional, inter-operator of reasons caused by slow access speed.
2. The poor server performance site, the capacity is limited, the face of sudden large flow could not carry crash the server.
3. Bandwidth small, a little more website traffic will slow down even open open site.
4. often suffer DDOS ***, take up a lot of traffic to be malicious.
The website pictures can be excessive, each visit are required to load resources, leading to slow to open web pages.
Demand determines the development of technology, in this environment, CDN and Site Acceleration services came into being. TTCDN popular understanding is the site acceleration and defensive ***, CPU load balancing can solve the cross-operator, cross-regional, server load capacity is too low, the bandwidth is too small and so slow to open the site to bring other issues.
