software similar to Nginx/lvs/haproxy, which is implemented at the software level, so it's very inexpensive.At present, the structure of the Web site architecture is generally more reasonable: the Web front-end uses nginx/haproxy+keepalived as the load balancer, and the backend uses the MySQL database as a master and read-write separation, using the lvs+keepalived architecture. Of course, according to the specific needs of the project plan.The following is the respective characteristics and app

Apache in the processing of dynamic has

sample cardinality (up to 200), and some combine two sub models to handle both fast and slow updates. In fact, the selection of replaced samples to update the background model, in essence, is the sample life problem, the traditional way to use the first out of the replacement strategy. The probability of each sample being selected as a replacement sample is equal in the vibe background model, which is independent of the length of the sample's existence time, which guarantees that the sample lif

Only when the last element of the data is inserted and deleted. It's quicker than that. The list simply needs to change the node information within the node that is necessary to change it. There is no need to change the memory address of the
