CDNs are not all created equal. Some are great in North America but not so much in South America. Some CDNs scream in the EU and then fall down in the Philippines.
And then there is China.
There are huge gaps in the performance between the regional CDNs and the global CDNs in places like Brazil and Russia. However, there is no greater place than China that epitomizes the importance of deploying regional CDNs. The performance differential between the regional CDNs and everyone else in China is vast.
If an enterprise is trying to have reasonable performance in China, it must utilize a regional CDN.
For today’s data-driven experiment, I chose three native Chinese CDNs. We will take a look at how they are all doing from inside the country. But first, to give you a flavor for the difference in performance of these regional CDNs with the Global CDNs, let’s look at the average latency over a 24-hour period as measured from within China. I will obfuscate the names of the Global CDNs. This is latency, so lower is better.
All of these reports are freely available in the Cedexis Radar reports section. If you do not have a account, I urge you to get one and explore these findings for yourself.
As you can see, all three of the Chinese CDNs that we evaluated here destroyed all of the Global CDNs by a huge margin with regard to latency. They do the same on throughput and availability, as well.
The global CDNs just do not cut it in China.
If you are planning on using a regional CDN in China, then what is the difference between the CDNs that are there? It is obvious that choosing a native CDN is important, but how do you choose which one? There are already some large competitors there (and more on the way)…. how to choose the best?
The three native Chinese CDNs are:
