Baidu Cloud Acceleration is Baidu's platform that provides acceleration and security protection for websites, launched in April 2014, which is free of charge with Baidu Accelerator as everyone knows beforeCDNThere is a connection and a difference, simply put: Baidu and Accelerator began dating in August 2013, and until May 2014, Baidu and Accelerator officially broke up.
In just half a year of dating with Baidu, Accelerator's CDN service has been recognized by many people, and Accelerator itself has also grown, but now Baidu has abandoned Accelerator and changed to focus on self-operated CDN services.

1. Why use Baidu Cloud Acceleration Free CDN Service?

1. Baidu Cloud accelerates through intelligent DNSParsingand other technologies to direct users visiting the website to the nearest fastest node, and utilize cache, pagesOptimizedCompression, back-to-origin merging and other technologies greatly improve the access speed of the website, while saving a lot of server and bandwidth resources of the website itself.
2. In terms of security protection, Baidu Cloud Acceleration can simultaneously protect against more than ten hacker infiltrations, including SQL injection, XSS, web server vulnerabilities, application vulnerabilities, and file access control issuesattackand SYN Flood, UDP Flood, ICMP Flood, TCP Flood, and CCDDoS attacks
3. Baidu Cloud Acceleration provides free CDN services, which can speed up website access and protect websites from attacks, these two features are claimed to have by other domestic free CDNs, and Baidu Cloud Acceleration also has the feature: support "Baidu spider DNS synchronization function".
4. The official document says: "When the cloud accelerates the cluster becausehardwareBreakdownOr the computer roomInternetWhen the fault is offline due to faults and other reasons, the faulty cluster will be automatically removed through intelligent DNS within 10s, and the DNS information will be automatically synchronized with Baidu Spider to prevent Baidu Spider from still accessing the IP of the faulty node due to DNS caching problemsSearch engineStability of weights. ”
5. If you have experience in website moving and other experiences, you must know that after the domain name is resolved to the new space, Baidu Spider still visits the old space, and generally after a week it will "realize" that the domain name has pointed to the new space, and in just a few days, it is often a very big blow to the authority of a grassroots website, in contrast, Google's spider is updated in real time.
6. Baidu Spider's "sluggish" response can be seen in a server adjustment before the tribe: the relationship between the unstable website server and Baidu in the process of building a website, in short, using Baidu Cloud acceleration is not because it is freeCDN accelerationfunction, but may be as the official document says: "Baidu Cloud Acceleration is a service launched by Baidu".


2. Baidu Cloud accelerates the use of free CDN acceleration services in China

1. Baidu Cloud Acceleration official website:

2. In addition, CDN acceleration lines can be set separately in the line types of Baidu Cloud Acceleration, such as China Telecom, China Unicom, Mobile, etc., some friends may be worried that the IP address accessed by the website after using CDN will become a shared IP, where we can set the line type as "search engine" and set a DNS resolution separately.


3. Judging from the server address returned by the ping of CNAME given by Baidu Cloud Acceleration, it seems that there is only one node in the free version of Baidu Cloud Acceleration.




4. Summary of Baidu Cloud Acceleration Free CDN Usage

At present, Baidu Cloud Acceleration is still in the public beta period, if you have not used Baidu Acceleration before, you need to use an invitation code to start using Baidu Cloud Acceleration now, friends who do not have an invitation code do not have to worry, I believe that Baidu Cloud Acceleration will soon be open for registration and use, and the effect of Baidu Free CDN remains to be seen.
2. From a functional point of view, Baidu Cloud Acceleration is a product similar to Accelerator, Security Treasure, and 360 CDN, focusing on security cards, but Baidu Cloud Acceleration has the Baidu spider DNS synchronization function, forSEOIt is still good, I believe that Baidu will take Baidu Cloud Acceleration as its main product in the future.
