The following brings you what is the polling and consistency hash of application load balancing, hoping to give you some help in practical application. There are many things involved in load balancing, there are not many theories, and there are many books on the Internet. Today, we will use the accumulated experience in the industry to do an answer.

1. Polling:

Advantages: requests to backend applications are more uniform, making each CVM basically balanced: with the increase of backend application servers, the cache hit rate decreases. This approach will not cause one of the servers to be overloaded because of hot issues.

2. Consistent hash

Advantages: the same request will be forwarded to the same server, and the hit rate will not decrease due to the increase of the server: because the same request will be forwarded to the same server, it may cause some server to be overloaded or even cause service problems.

3. Summary

In the case of low load, it is recommended that the consistent hash hotspot request is degraded, and polling is recommended. If the request data is regular, you can consider the weighted consistent hash.

After reading the above polling and consistency hash about application load balancing, if you have anything else you need to know, you can find out what you are interested in in the industry information or find our professional and technical engineer to answer it. Technical engineers have more than ten years of experience in the industry.
