Akamai

The best acceleration effect should be Akamai, a traditional CDN manufacturer, but it is expensive. AKAMAI is the world's largest CDN service provider. It's fast anywhere. Tencent also uses this. Small users can't buy it, but you can use RACKSPACE's CLOUDFILE to automatically use AKAMAI to accelerate. RACKSPACE needs to call to confirm, which is very convenient.

AMAZON CloudFront

In recent years, some Internet giants sell idle bandwidth as CDN, which represents Amazon's Cloudfront and Google's Cloudflare, and the price can be very low. However, it is said that the performance of cloudflare is mediocre, and there are serious security problems. At present, cloudfront is still the one with high performance / price ratio overseas.

In addition, there are some domestic manufacturers who use the infrastructure of cloudfront to package and sell, and the price will be cheaper than buying directly from Amazon, mainly for European and American languages, but Chinese access to CDN is often not open or very slow.

MAXCDN

It is good for Europe and America. Now there are Asian nodes, but in Singapore. Domestic visit is still slow, the parent company NETDNA is very strong, you can go to consult.

There are other brands, such as limelight, which is also a big company, which requires an advance of US $3000, otherwise it will not be used. CLOUDFILE is fast everywhere, pay attention to flow control, being attacked will cost a lot of money.
